Patch created on December 7 2012 Patch Case#: 87250 //**************************************************************** This patch addresses known software issues for Stratix V, Arria V and Cyclone V devices in the Quartus II software version 12.1. The device patches are cumulative. ============================================= The following issues are addressed in 0.dp1: ============================================= -------------------- Issue 1 (case 86040) -------------------- TCO reported for wide data widths in M20K blocks with registered outputs in Stratix V devices is incorrect TCO values reported by the TimeQuest Timing Analyzer for Stratix V M20K blocks that use more than 16 bits and that have registered outputs may be pessimistic. TCO values of output register bits 16 to 39 reported by TimeQuest can be pessimistic by as much as 500 ps. TCO values for bits 0 to 15 are reported correctly. For up-to-date information about Stratix V timing model issues found in the Quartus II software version 12.1, refer to solution number rd11162012_922 in the Altera Knowledge Base. -------------------- Issue 2 (case 86202) -------------------- Timing paths from Stratix V DSP input ports are not analyzed in some circumstances. In designs that target Stratix V devices, if DSP outputs are registered, but the RESULT ports are disconnected, which is common among filters, then any paths from the DSP input port to the DSP output register are not analyzed for timing. For up-to-date information about Stratix V timing model issues found in the Quartus II software version 12.1, refer to solution number rd11162012_922 in the Altera Knowledge Base. -------------------- Issue 3 (case 86732) -------------------- Timing delays reported from QCLK to SCLK for QCLKs 73 to 91 in Stratix V devices are incorrect For designs that target Stratix V devices, the timing delay from Regional Clocks (QCLKs) to Spine Clocks (SCLKs) on the right center and left center of the device (QCLKs 73 to 91) is incorrectly reported as zero. The actual delay for speed grade 3 devices at 85°C is approximately 1 ns. For up-to-date information about Stratix V timing model issues found in the Quartus II software version 12.1, refer to solution number rd11162012_922 in the Altera Knowledge Base. -------------------- Issue 4 (case 86556) -------------------- Quartus II might trigger the following internal error for Cyclone V E50 designs with HMC instantiated: Internal Error: Sub-system: ASM, File: /quartus/comp/asm/asm_dev_cyclone5.cpp, Line: 1238 ASM_MODEL::s_atom_asm_index != -1 -------------------- Issue 5 (case 59936) -------------------- This patch enables unbonded CMU for Arria V C3 device F896 package under INI control. Please contact your Altera FAE/AE if you need this support. -------------------- Issue 6 (case 83655) -------------------- External Memory Interfaces that use pins from banks 8E or 7E on the following Stratix V devices will not function correctly in hardware. 5SEE9, 5SEEB, 5SGXEA9, 5SGXEAB, 5SGXEB9, 5SGXEBB, 5SGXMA9, 5SGXMAB, 5SGXMB9, 5SGXMBB -------------------- Issue 7 (case 83710) -------------------- Arria V RX Equalizer Setting mapping in Quartus II software is incorrect. -------------------- Issue 8 (case 84782) -------------------- Can't select /64 refclk frequency for 10312.5Mbps in Stratix V Low Latency PHY IP from Mega Wizard. -------------------- Issue 9 (case 84923) -------------------- PLL code might cause errors in post-fit flow for parameters nreset, fractional_carryout, and m_cnt_prst. This patch prevents those errors and recognizes the valid parameter values. -------------------- Issue 10 (case 85969) -------------------- Quartus II software might trigger the following internal error in fitter stage for Partial Reconfiguration revisions: Internal Error: Sub-system: FITCC, File: /quartus/fitter/fitcc/fitcc_pr_bits_utility.cpp, Line: 895 pr_region == parent_region_id || parent_region_id == MSF_STATIC_REGION_ID The problem might occur for PR designs that use both reconfigurable, and non-reconfigurable LogicLock regions. The error is caused by a false positive in a post-routing verification step. This patch fixes the faulty logic in the verification step. -------------------- Issue 11 (case 81664) -------------------- Internal Error: Sub-system: ASMDB, File: /quartus/db/asmdb/asmdb_param.cpp, Line: 522 iter != m_enum_map->end() -------------------- Issue 12 (case 86164) -------------------- This patch supports junction temperature QSF settings for Cyclone V devices. -------------------- Issue 13 (case 86260) -------------------- Unexpected signal behavior on the pins within 8A and 8B IOBANK of Arria V F780 package due to one of the VREF pads not being configured correctly. -------------------- Issue 14 (case 86274) -------------------- This patch provides the following support: 1. Exposes a user-requested ZQ calibration port on UniPHY, similar to user refresh. The port is activated by setting alt_mem_if_pingpong_ctl=on, which increases the max pending read/write commands that can be handled by the controller (for efficiency reasons). 2. Exposes a set of ports for the refresh controller component. These ports consist of the tbp_empty, cmd_gen_busy, and sideband_in_refresh signals. These signals are connected to the refresh controller by the customer when INI alt_mem_if_enable_refctrl=on is set. -------------------- Issue 15 (case 86377) -------------------- This patch adds support for Arria V 5AGXFB3H4F35C4ES under dev_password control. Please contact your Altera FAE/AE if you need this device support. -------------------- Issue 16 (case 86494) -------------------- Quartus II software requires a developer license when RBCGEN_ERROR_TO_CRITICAL_WARNING INI is used. -------------------- Issue 17 (case 86375) -------------------- Analog reconfig IP: Preemphasis - pre-tap and 2nd post-tap mappings are not correct in Quartus II version 12.1. -------------------- Issue 18 (case 86651) -------------------- Any Arria V part based on C3 die that uses the right side Levelling Delay Chains will not function as expected. Root Cause: Connections from DLL to the Levelling Delay Chains on the right side were using the wrong DLL output ports. -------------------- Issue 19 (case 83680) -------------------- Internal Error: Sub-system: ASMDB, File: /quartus/db/asmdb/asmdb_offset_cache.cpp, Line: 860 Illegal setting -------------------- Issue 20 (case 84482) -------------------- This patch enhances the UniPHY calibration algorithm for all V-series families. The enhancement adds an extra read calibration after write calibration, which provides better centering of the read strobe/clock within the read data window. This enhancement improves robustness at the highest supported frequencies such as 933MHz DDR3 on Stratix V C2 devices and 800MHz DDR3 on Stratix V 800MHz C3 devices. ============================================= The following issues are addressed in 0.dp2: ============================================= -------------------- Issue 21 (case 87286) -------------------- Internal Error: Sub-system: ASM, File: /quartus/comp/asm/asm_caddy_base.cpp, Line: 273 block_index != static_cast(-1) This patch fixes the internal error in Quartus II Assembler for Stratix V 5SGXA9, 5SGXAB, 5SGXB9, and 5SGXBB devices. -------------------- Issue 22 (case 87417) -------------------- This patch enables POF support for Stratix V 5SGSD8 and 5SGSD6 devices. -------------------- Issue 23 (case 86258) -------------------- Certain systems are not able to successfully load the USB Blaster II device driver. If the system error message is 'The parameter is incorrect', use this updated driver package when re-installing the USB Blaster II device driver. -------------------- Issue 24 (case 86633) -------------------- This patch adds a new stage called "Read Calibration - VFIFO After Writes" to External Memory Interface debug toolkit. -------------------- Issue 25 (case 87328) -------------------- The patch fixes a fatal error in the Quartus II Assembler when user leaves stratixv_output_alignment.enaoutputcycledelay and stratixv_output_alignment.enaphasetransferreg ports floated in non-scan chain mode operation in ALTDQ_DQS2 MegaCore for Stratix V devices. *** Fatal Error: Access Violation at 0X00000000015E2DD0 Module: quartus_asm.exe Lock in use: 9 Stack Trace: 0x22dcf: CDB_SIGNALPROBE_INFO::reset_from_file + 0x123f (db_cdb) 0x3ab56: ASMIO_MODULAR_IO_PIN_MODEL::~ASMIO_MODULAR_IO_PIN_MODEL + 0x11676 (comp_asmio) -------------------- Issue 26 (case 87329) -------------------- This patch enables the bus hold circuitry for differential I/O for Arria V GT devices under INI control. Please contact your Altera FAE/AE if you need this support. -------------------- Issue 27 (case 87239) -------------------- This patch presents the correct sets of fPLLs in floorplans for Stratix V 5SGXEAB, 5SGXEA9, 5SGXMAB, 5SGXMA9, 5SEE9, and 5SEEB devices.
