Items listed in the following table represent cases in which the behavior of the current release of the Quartus II software is different from a previous version.Description Version 9.1 SP1 The following Cyclone IV GX devices are not supported in the Quartus II software version 9.1 SP1 and later:
WorkaroundEP4CGX15BN11C6 EP4CGX15BN11C7 EP4CGX15BN11I7 To reserve a ASDO/DATA1 pin, use a RESERVE_DATA1_AFTER_CONFIGURATION assignment. To reserve a nCSO pin, use a RESERVE_FLASH_NCE_AFTER_CONFIGURATION assignment.For the Cyclone IV GX device family, the RESERVE_ASDO_AFTER_CONFIGURATION assignment is not available. In the Quartus II software version 9.1, you could use a RESERVE_ASDO_AFTER_CONFIGURATION assignment to reserve both ASDO/DATA1 and nCSO pins in Bank 9 as user I/O pins in user mode. In the Quartus II software version 9.1 SP1 and later, the RESERVE_ASDO_AFTER_CONFIGURATION assignment is not available for the Cyclone IV GX device family. This change enables Fast Passive Parallel (FPP) configuration for some Cyclone IV GX devices, allowing you to reserve the ASDO/DATA1 pin while keeping the nCSO pin available for general purpose I/O. In the Quartus II software version 9.1, RX PCS and TX PCS clock names reported by the TimeQuest Timing Analyzer are incorrect. For example, in the Quartus II software version 9.1, the TimeQuest Timing Analyzer might report xcvr_alt4gxb_component|receive_pcs0|clkout as xcvr_alt4gxb_component|receive_pcs0|recove redclk In the Quartus II software version 9.1 SP1 and later, the clock names reported by the TimeQuest Timing Analyzer are correct.If you are using SDC assignments written for the Quartus II software version 9.1 in the Quartus II software version 9.1 SP1 or later, verify that your RX PCS and TX PCS clock names are correct.Version 9.1 ACEX, APEX, FLEX, and HardCopy Stratix device families are not provided with the Quartus II software version 9.1 and later. Use the Quartus II software version 9.0 SP2 or earlier to support those devices. The Quartus II software version 9.0 and the associated service packs will remain available on the Altera website (). Use the Quartus II software version 9.1 SP2 or earlier, Mentor Graphics ModelSim-Altera Edition, or a third-party EDA simulator and waveform editor.The Simulator and the Waveform Editor will not be provided in future versions of the Quartus II software beginning with version 10.0.April 2010Altera CorporationQuartus II Software Version 9.1 SP2 Release NotesPage 6Changes to Software BehaviorDescription For Arria II GX, Cyclone III, Cyclone IV, HardCopy III, HardCopy IV, Stratix III, and Stratix IV devices, Analysis and Synthesis performs timing-driven synthesis by default. Changes to the default assignment settings in the Quartus II software include the following:Workaround To turn off timing-driven synthesis, turn off Timing-Driven Synthesis on the Analysis and Synthesis page of the Settings dialog box.The default value of PARALLEL_SYNTHESIS has changed to On. For Arria II GX, Cyclone III, Cyclone IV GX, HardCopy III, HardCopy IV, Stratix III, and Stratix IV devices, the default value of SYNTH_TIMING_DRIVEN_SYNTHESIS has changed to On.Changes to TimeQuest Timing Analyzer behavior in the Quartus II software version 9.1 include the following:set_max_skew now includes utsu, uth, utco, from_clock, to_clock, and clock_uncertainty. In designs that target Stratix III devices, if ENA_REGISTER_MODE of the ena port is set to DOUBLE_REGISTER, the internal register-to-register timing of the enable signal is guaranteed by design and is excluded from timing analysis. Stratix III I4 timing models have been updated in the Quartus II software versions 9.0 SP2 and 9.1. Only timing delays in Low Power mode LABs and Low Power mode MLABs in I4 industrial speed grade devices are affected. This change in the timing models may affect your static timing analysis and fitting result. Existing designs that target Stratix III I4 devices might exhibit some degradation in performance after timing analysis with the TimeQuest Timing Analyzer in the Quartus II software version 9.1. However, a full recompilation of the design removes any degradation in performance. Other speed grade devices (I3 and I4L at 1.1V; I4L at 0.9V; and all commercial speed grades) are not affected. If your design works correctly in your hardware system, Altera recommends that you take no action. Otherwise, Altera recommends that you fully recompile the design.Mentor Graphics ModelSim-Altera Edition no longer includes the alt_vtl library used to simulate MAX+PLUS II designs. In designs that target Stratix IV devices, ALTGX megafunction instances created with the Use external termination option turned on in the Quartus II software version 9.0 and earlier did not disable internal termination. The Quartus II software version 9.1 disables internal termination when the Use external termination option is turned on. Starting in the Quartus II software version 9.1, an ALTGX megafunction generates only a 1-bit rateswitch port for PCIE Gen 2 x4/x8 configurations. In previous versions of the Quartus II software, an ALTGX megafunction generated 4- or 8-bit rateswitch ports, of which only bit 0 was used.Use the alt_vtl library from the Mentor Graphics ModelSim-Altera Edition version 6.4a. This change in software behavior decreases the resistance in designs that use external termination and may change measured signal characteristics compared to those measured in previous versions of the Quartus II software. This change in software behavior does not affect designs that use internal termination.Quartus II Software Version 9.1 SP2 Release NotesApril 2010 Altera CorporationKnown Issues & WorkaroundsPage 7Known Issues & WorkaroundsGeneral Quartus II Software IssuesIssue Version 9.1 SP1 Quartus II Help in the Quartus II software version 9.1 SP1 and earlier incorrectly states that the Fitter does not include set_max_skew constraints in design optimization, however, set_max_skew constraints are optimized by the Fitter. The set_max_skew command is available in the ::quartus::sdc_ext 1.0 Tcl package. If you use the Remote System Upgrade configuration scheme to create a Programmer Object File (.pof) to update a device programmed with a .pof from a previous version of the Quartus II software, the Quartus II software version 9.1 SP1 might generate an internal error similar to the following: Internal Error: Sub-system: PGMIO, File: /quartus/pgm/pgmio/pgmio_pof_diff.cpp, Line: 635 data do not match If you implement an ALTCLKCTRL megafunction and then run the Design Assistant, the Design Assistant might generate a message similar to the following: Critical Warning: (Critical) Rule C101: Gated clock should be implemented according to the Altera standard scheme. Found 1 node(s) related to this rule. You may safely ignore this message. Use the version of the Quartus II software you used to generate the original .pof to create the updated .pof. WorkaroundApril 2010Altera CorporationQuartus II Software Version 9.1 SP2 Release NotesPage 8Known Issues & WorkaroundsIssue Version 9.1 If you use variable part select with two-dimensional arrays, the Quartus II software version 9.1 SP1 generates an error similar to the following: no support for variable part select of multidimensional arrays (System Verilog) The Quartus II software version 9.1 does not correctly synthesize variable part select with two-dimensional arrays. For example, the following Verilog statements are not synthesized correctly: logic s[3:0] ; logic [0:w-1][3:0] s = m[i+1]; The Quartus II software version 9.1 does not correctly synthesize disable statements when the disable statement refers to a labeled statement. For example, the following Verilog statements are not synthesized correctly: lbl: out1 ,=r1^r2; Running Partition Merge after importing a design with empty partitions created with a previous version of the Quartus II software results in the following error:Error: Missing required database file.WorkaroundDo not use variable part select with two-dimensional arrays. Use multiple constant part selects such as m[2+:1], and then choose from them.Rewrite your code so that the statement is surrounded by a begin-end block and name the block after the begin keyword. For example, the following is synthesized correctly: begin: lbl out1 &=r1^r2; Run Analysis and Synthesis before running Partition Merge.For the ALTFP_MATRIX_MULT megafunction, the maximum column and row sizes for input matrices is limited to 64. If you attempt to add the ALTFP_MATRIX_MULT megafunction to your project with the MegaWizard Plug-In Manager, the MegaWizard Plug-In Manager fails to add the altfpc_lib library to your project. If you attempt to add the ALTFP_MATRIX_INV megafunction to your project with the MegaWizard Plug-In Manager, the MegaWizard Plug-In Manager fails to add the altfpc_lib library to your project. Manually include the altfpc_lib.v or altfpc_lib.vhd file in the project.Manually include the altfpc_lib.v or altfpc_lib.vhd file in the project.Quartus II Software Version 9.1 SP2 Release NotesApril 2010 Altera CorporationKnown Issues & WorkaroundsPage 9Issue The ALTFP_CONVERT megafunction fixed-point-to-floating-point and floating-point-to-fixed-point features are supported only from a command prompt.Workaround To create an ALTFP_CONVERT megafunction that converts a single precision value to a Q16.16 fixed point value for a design that targets a Stratix III device, type the following at a command prompt: clearbox cbx_altfp_convert CBX_AUTO_BLACKBOX=ALL OPERATION=FLOAT2FIXED WIDTH_EXP_INPUT=8 WIDTH_MAN_INPUT=23 WIDTH_INT=16 WIDTH_RESULT=32 DEVICE_FAMILY=STRATIXIII clock dataa result cbx_file=float2fixed.v To create an ALTFP_CONVERT megafunction that converts a Q16.16 fixed point value to a single precision value, thy the following at a command prompt: clearbox cbx_altfp_convert CBX_AUTO_BLACKBOX=ALL OPERATION=FIXED2FLOAT WIDTH_EXP_OUTPUT=8 WIDTH_MAN_OUTPUT=23 WIDTH_INT=16 WIDTH_DATA=32 DEVICE_FAMILY=STRATIXIII clock dataa result cbx_file=fixed2float.vAt a resolution of , the MegaWizard Plug-in Manager cannot display settings for the ALTREMOTE_UPDATE, ALTPLL, and ALTGX megafunctions. When a RAM is inferred under all the following conditions, the synthesized circuit is not guaranteed to be correct:Change your display settings to a higher resolution.The read from and write to the memory occur in the same always block or process. The always block or process that reads/writes to the memory array is combinational.To solve this problem, either disable RAM inference or rewrite the HDL description of the RAM. RAM inference can be disabled by setting the auto_ram_recognition variable to Off. Alternatively, a different HDL description can be used for the RAM (refer to the &Inferring Memory Functions from HDL Code& chapter in the Quartus II Handbook). In the Device page in the Settings dialog box, click Migration Devices. In the Migration Devices dialog box, click OK to close the dialog box. In the Device page, click OK to close the page. Regenerate the ALTGX instances.The write assignment happens before the read. When you compile a project and then try to open the Assignment Editor, the Quartus II software displays an internal error if the selected devices in the Migration Devices dialog box include EP4SGX290KF40C3, EP4SGX360KF40C3, and EP4SGX530KH40C3. In projects targeting Stratix IV GT and Arria GX devices, transceivers with ALTGX instances created in the Quartus II software version 9.0 SP1 might display an internal error in versions of the Quartus II software later than 9.0 SP1: Internal Error: Sub-system: FHSSI, File: /quartus/fitter/fhssi/fhssi_cell_group.c pp, Line: 1463 aux_cell != NULLApril 2010Altera CorporationQuartus II Software Version 9.1 SP2 Release NotesPage 10Platform-Specific IssuesPlatform-Specific IssuesWindows Platforms OnlyIssue Version 9.1 If you attempt to install the Quartus II software version 9.1 to a disk drive that uses a FAT32 file system, installation fails and Windows generates an error similar to the following: File Error The following error occurred on the file &file name&.

You may safely ignore this message. WorkaroundVersion 9.1 The Quartus II Web Edition software version 9.1 for Linux is a beta release. This beta version allows you to experience the software before it is officially released, but it may have limited-feature functionality. If you access the TimeQuest Timing Analyzer GUI using remote access tools such as VNC, Xvnc, and Exceed, the GUI might become unresponsive. The Toolbar dialog box does not close. The Quartus II GUI cannot be resized. This issue is corrected in the Quartus II software version 9.1 SP1 For a complete listing of features available with the Quartus II Web Edition software version 9.1 for Linux, refer to the Quartus II Web Edition Software download site. Refer to the solution available at /support/kdb/solutions/rd.html Close the Customize dialog box before attempting to close the Toolbar dialog box Refer to the solution available at /support/kdb/solutions/rd4.html.Quartus II Software Version 9.1 SP2 Release NotesApril 2010 Altera CorporationDevice Family IssuesPage 11Device Family IssuesArria II GXIssue Version 9.1 SP1 In the Quartus II software, delay locked loops (DLLs) are numbered from 0 to 1. However, Chapter 7 &External Memory Interfaces in Arria II GX Devices& in Volume 1 of the Arria II GX Device Handbook numbers DLLs from 1 to 2. Use numbers 0 to 1 to refer to DLLs when you make location assignments in the Quartus II software. WorkaroundVersion 9.1 Netlists that have been exported using the Quartus II software version 9.1 cannot be imported to later versions of the Quartus II software. For designs targeting EP2AGX45 and EP2AGX65 devices, the Quartus II software version 9.1 might incorrectly generate programming files, causing functional failures in some devices. This issue can occur when you program your device with the Quartus II Programmer or when you use any of the following file formats: .pof, .rbf, .hexout, .ttf, .rpd, .jic, .jbc, and .svf. This issue is corrected in the Quartus II software version 9.1 SP1. The Memory Initialization File (.mif) Generator might not create accurate data for designs that target the Arria II GX device family. This issue is corrected in the Quartus II software version 9.1 SP1. In the Quartus II software version 9.1 and earlier, if an MLAB is configured without a clock enable and the MLAB does not share the same clock routing as its datain registers, write failures may occur in designs that target Stratix III, Stratix IV GX, or Arria II GX devices. In this configuration, the Assembler incorrectly grounds the clock enable of the MLAB and disables the write operation of the MLAB. This issue is corrected in the Quartus II software version 9.1 SP1. Compilation of a design targeting an Arria II GX device that uses LVDS without Dynamic Phase Alignment (DPA) and a data rate higher than 840Mbit/s generates a report panel entitled &Transmitter/Receiver Package Skew Compensation& to guide you to compensate for the skew on your board trace. In the &Estimated TCCS/Sampling Window Reduction& column (the last column of the report panel), the delay reduction reported may be inconsistent with the value reported in &Recommended Trace Delay Addition.& For designs that use Arria II GX transceivers, generation of HSPICE Simulation Deck files with the EDA Netlist Writer is not supported. Use the Recommended Trace Delay Addition value to compensate for the skew and ignore the Estimated TCCS/Sampling Window Reduction values. If your design compiled in the Quartus II software version 9.1 or earlier and has run successfully in hardware, no action is required. Otherwise, refer to the solution available at /support/kdb/solutions/rd 28.html. In the generated .mif, change bit numbers 6 and 7 of the second word of the MIF header (MIF address &1&) from &00& to &10&. Note that the bit counting starts at 0. Recompile your design using the Quartus II software version 9.1 SP1 or later. Refer to the solution available at /support/kdb/solutions/rd 71.html.To generate HSPICE Simulation Deck files, create a revision of your design and remove the transceiver pins from the revision.April 2010Altera CorporationQuartus II Software Version 9.1 SP2 Release NotesPage 12Device Family IssuesCyclone IIIIssue Version 9.1 SP1 The TimeQuest Timing Analyzer overestimates LVDS buffer output delays. This issue is corrected in the Quartus II software version 9.1 SP2 For designs that target Cyclone III, Cyclone IV, Stratix III, and Stratix IV devices, Design Space Explorer (DSE) selects the best result incorrectly. This issue is corrected in the Quartus II software version 9.1 SP2. Manually identify the best result by performing the following steps: 1. Specify the exploration parameters you want DSE to use. 2. On the DSE Options menu, turn on Archive All Compilations. 3. Run DSE. 4. On the DSE Processing menu, click View Last DSE Report for Project. 5.

WorkaroundDo not use the CRC feature with a core voltage of 0.9 V.Version 9.1 SP1 For designs that target Cyclone III, Cyclone IV, Stratix III, and Stratix IV devices, Design Space Explorer (DSE) selects the best result incorrectly. This issue is corrected in the Quartus II software version 9.1 SP2. Manually identify the best result by performing the following steps: 1. Specify the exploration parameters you want DSE to use. 2. On the DSE Options menu, turn on Archive All Compilations. 3. Run DSE. 4. On the DSE Processing menu, click View Last DSE Report for Project. 5. In the DSE Report, review the Detailed Results table to correctly identify the best exploration point. The Detailed Results table is located in the Flow Summary section. If you want to open the best design revision in the Quartus II software, open the Quartus II Archive File (.qar) corresponding to the best exploration point you identified in step 5. The .qar file is located in the &design directory&/dse directory. If you configure an M144K memory block as x36 on port A or x18 on port B and data[0] is not connected, the block's other data lines might not be routed correctly.

However, Chapter 8 &External Memory Interfaces in Stratix II Devices& in Volume 1 of the Stratix III Device Handbook numbers DLLs from 1 to 4.Use numbers 0 to 3 to refer to DLLs when you make location assignments in the Quartus II software.Version 9.1 In the Quartus II software version 9.1 and earlier, if an MLAB is configured without a clock enable and the MLAB does not share the same clock routing as its datain registers, write failures may occur in designs that target Stratix III, Stratix IV GX, or Arria II GX devices. In this configuration, the Assembler incorrectly grounds the clock enable of the MLAB and disables the write operation of the MLAB. This issue is corrected in the Quartus II software version 9.1 SP1. In reconfigurable ALT2GXB instances, the PLL logical number and PLL location number must match in order to work properly in hardware. If the logical number and location number do not match, the Quartus II software generates a message similar to the following: Error: Can't place GXB CMU PLL Ensure that the PLL logical number and PLL location number match. If your design compiled in the Quartus II software version 9.1 or earlier and has run successfully in hardware, no action is required.

In this configuration, the Assembler incorrectly grounds the clock enable of the MLAB and disables the write operation of the MLAB. This issue is corrected in the Quartus II software version 9.1 SP1. With the ALTGX megafunction, if your design uses dynamic protocol reconfiguration from x4 bonding in basic mode to XAUI or PCIE x4 protocols, simulation fails. The ALTGX_RECONFIG megafunction cannot support both Tx data rate division and channel/PLL reconfiguration simultaneously.

ALTGX receivers in Basic (PMA Direct) mode may encounter a hardware hold failure in the transfer to core logic if default timing constraints are used, even after passing timing analysis with the preliminary timing model.WorkaroundTo ensure that the core registers latch the receiver's data with the same clock edge that the RX PMA launched the data with, add the following line to your SDC: set_multicycle_path -setup -from [get_registers *alt4gxb*|wire_receive_pma*_recoverdata out*] 0Stratix IV GTIssue Version 9.1 During fitting, timing analysis, or power analysis, incorrect voltage settings of the VCC, VCCA, or VCCD power rails can generate the following error message: Error: The supply voltage value &voltage& applied to the &power supply& power rail is illegal for the currently selected device. Select supply voltage values with the Voltage tab of the Settings dialog box. WorkaroundHardCopyIssue Version 9.1 SP1 Because on-chip delay variation modeling for HardCopy III and HardCopy IV is missing from the timing models in the Quartus II software version 9.1 SP1 and earlier, a design that targets a HardCopy III or HardCopy IV device might not meet timing during PrimeTime analysis although the TimeQuest Timing Analyzer reports that the design meets timing. In the Quartus II software, delay locked loops (DLLs) are numbered from 0 to 3. However, Chapter 7 &External Memory Interfaces in HardCopy IV Devices& in Volume 1 of the HardCopy IV Device Handbook and Chapter 7 &External Memory Interfaces in HardCopy III Devices& in Volume 1 of the HardCopy III Device Handbook number DLLs from 1 to 4.

The Quartus II software uses the Tcl version 8.5 API. Some Tcl syntax, such as regular expressions, may behave differently in your component's hw.tcl folder and in the Quartus II Tcl Interpreter. The Vectored Interrupt controller does not support VHDL simulation models. The output port reset value of a parallel input/output (PIO) module may be invalid if the Enable individual bit set/clear output register option is turned on for the output register and the multi-bit output port reset value is not zero. When adding components to your system, SOPC Builder might generate messages similar to the following: Warning: set_module_property on deprecated property class_name, please use name instead Warning: set_module_property on deprecated property preview_elaboration_callback, please use elaboration_callback instead Warning: set_module_property on deprecated property preview_validation_callback, please use validation_callback instead In the System Console, if you set DC gain to 4, the transceiver_reconfig_analog_get_rx_dcgain and transceiver_reconfig_analog_set_rx_dcgain Tcl commands generate the following error: Invalid DC Gain value In designs that target Arria II GX or Stratix IV devices, if you set DC gain to 2 with the ALTGX MegaWizard, the effective DC gain of the receiver is incorrectly set to 1. In the System Console, if you call design_load twice on the same project, you lose plugin services. After you configure your ALTGX megafunction instance, use the ALTGX_RECONFIG megafunction to set the DC gain to 2. Call design_load only once per design, per System Console session. If you need to reload the design, start a new System Console. Select a DC gain value between 0 and 3. On the Basic Settings page of the MegaWizard interface for the PIO core, turn off Enable individual bit set/clear output register. You may safely ignore these messages. Use the Tcl version 8.0 API command set.

WorkaroundQueue uses an element data type that is not currently supported.On Linux computers, attempting to run the Mentor Graphics ModelSim-Altera or Mentor Graphics ModelSim-Altera Starter Edition vsim command from the &path to ModelSim&/bin directory generates an error similar to the following: Error: cannot find /apps/altera/quartusII/9.1.linux.cb/mod elsim_ase/bin/linux/vsim Run the vsim command from the &path to ModelSim&/linuxaloem directory.Memory Interface IssuesIssue Version 9.1 If a UNIPHY instance is generated in slave mode, the timing constraints are incorrect. In slave mode, the PLL is not instantiated inside the PHY, but is assumed to be external to the PHY. This issue is corrected in the Quartus II software version 9.1 SP1.WorkaroundManually edit the following two files:&core&/constraints/&core&_parameters.tcl. In this file, PLL output ports are identified by their names. If the PLL is external to the PHY, replace the names of the PLL output ports with the names of the PLL ports you intend to use. &core&/constraints/&core&.sdc. In this file, PLL output ports are referenced by prepending the UNIPHY hierarchy. If the PLL is external to the PHY, remove &${inst}|& from each PLL port reference. &core&_report_timing.tcl &core&.sdcIn the RLDRAMII GUI of the UNIPHY megafunction, the tQKH parameter is defined as a &percentage of half of a clock period.& However, in the generated timing constraints, the tQKH parameter is used as a &percentage of a full clock period.& As a result, the read hold margin, as defined in the timing constraints, is too optimistic. This issue is corrected in the Quartus II software version 9.1 SP1.Manually edit the following two files: to apply the tCKH corrective factor to the equations where tQKH is used. For example, change [ expr $tQKH * $tCK ] to [ expr $tQKH * $tCK * 0.45 ] where `0.45' is an example value of the tCKH parameter. (the tCKH parameter for your memory device can be obtained from the RLDRAMII data sheet).Quartus II Software Version 9.1 SP2 Release NotesApril 2010 Altera CorporationIssue If you use the ALTMEMPHY megafunction for DDR2 or DDR3 on discrete devices with dynamic parallel on-chip termination (OCT) and read or write operations occur close to each other, data written to the RAM might be corrupted.
