  • Support for 8-lane Gen2 Endpoint product has been enabled for Virtex-6 HXT
  • Synplify support
  • Option added to enable Buffering optimized for Bus Mastering Applications
  • License check removed
Resolved Issues

CR 550704: License checks removed
The Virtex-6 FPGA Integrated Block for PCI Express product no longer checks for license and does not require a pre-shipped license as of the 12.1 release.

CR 522983: Gen2 operation supported with 100 MHz Reference Clock
Gen 2 operation is now also supported with 100 MHz Reference Clock.

CR 510476: VHDL example design / testbench for Root Port Configuration now supported
VHDL example design and testbench for both the Endpoint and Root Port Configurations is now supported.

CR 531976: Synplify flow now supported in the ISE 12.1 software release
Synplify flow is now supported in the ISE 12.1 software release.

CR 535127: Option added to enable Buffering optimized for Bus Mastering application
New option has been added to CORE Generator interface to enable Buffering optimized for Bus Mastering applications.

CR 538257: Added support for 6VHX380T-FF1154, 6VHX380T-FF1923 and 6VHX255T-FF1923
Support for all HXT devices has now been enabled.

CR 531975: 8-lane Gen2 product is now supported in the Virtex-6 HXT devices
Support for 8-lane Gen2 product, in Virtex-6 HXT devices is now available.

CR 538644: 8-lane Gen2 product is now supported in the Virtex-6 LX130T device, in a -2 speedgrade
8-lane Gen2 product is now supported for 6VLX130T, in a -2 speedgrade, in the 12.1 release.

CR 535128: Root Port product hardware autonomously initiates Gen1-Gen2 speed change
The Root Port product now hardware autonomously initiates Gen1 - Gen2 speed change if possible.

CR 548630, 552700, 550490, 545280: GTX Production Settings Updated
GTX settings have been updated per Production GTX settings.

CR 551143: Core Generation from ISE software fixed
Issue resolved where Coregen Generation from ISE was failing.

CR 546697: LL Replay Timer default settings have been changed in GUI
LL Replay Timer default settings have been changed in the GUI, as previous values were not accounting for internal processing delays, causing Correctable errors (replays) when there is link traffic but no link errors.

CR 538239: New GUI option added to Disable TX ASPM L0s
New GUI options has been added to Disable TX ASPM L0s action. This option is recommended to be enabled for links that interconnect Xilinx Virtex-6 FPGA to any Xilinx component.

CR 539285: Workaround added for De-emphasis Value Error known restriction, for Root Port configuration
Work-around has been implemented for the known restriction "De-emphasis Value Error", in the Root Port Configuration, by setting PLDOWNSTREAMDEEMPHSOURCE attribute to 1b. For more information on the restriction, refer to the "Known Restrictions" section in the User Guide.

CR 539545: Root Port model provided for Endpoint product now passes Memory / I/O transactions to User side
Root Port model delivered with the Endpoint product has been updated to pass Memory and I/O transactions from the Endpoint to the User side.

CR 552777: Enabled PROM file generation for programming ML605
Enabled PROM file generation for programming ML605, in the implementation scripts.

CR 548864: Upgrade capability added
Upgrade capability added to enable generation of the latest version of the product for a previously customized project (from an XCO from the previous version of the core).

CR 553769: Default value of Acceptable L0s Exit Latency changed
Default value of the Acceptable L0s Exit Latency for an Endpoint product has been updated to a "Maximum of 64 ns".

CR 531980: GT Debug Ports option removed from CORE Generator GUI
GT Debug Ports (DRP) option has been removed from the CORE Generator GUI.

CR 555118: VHDL update
The VHDL source code has been updated for latest wrapper changes and also for issues with existing code, which was causing address on Read FIFO to be incorrect.

CR 539219: Constraints added for Configurations with User Clock 250 MHz
Constraints were added to the UCF and XCF for Configurations with User Clock set to 250 MHz.

CR 537545: PLL reset input changed
PLL reset input had been changed so it does not get reset at link-down. This enables the trn_clk to not be interrupted in thsi scenario.
