General Information
The LogiCORE Endpoint Block Plus for PCI Express is shipped with a free license. See (Xilinx Answer 33386) for more information.
The v1.12 core now includes source code for the Block Plus wrapper that instantiates the integrated block for PCI Express. The wrapper source code is contained in the directory named <project_name>/source. An ngc file is no longer delivered and the source code is synthesized as part of the user project. The synthesis scripts in the <project_name>/implement directory show examples of how to read in the source code for synthesis. Xilinx does not support any modifications made to the source code.
New Features
- ISE 11.3 software support - Source Code release - Configuration Write support (optional)
Resolved Issues
- CR 502953: Configuration Write Ability Enhancement The Endpoint Block Plus Core now optionally supports Writes to the Configuration Registers in the Integrated Block for PCI Express through the Configuration Port. Please refer to the LogiCORE IP Endpoint Block Plus for PCI Express User Guide for further information on enabling and using this feature.
- CR 513853: Virtex-6 FPGA Integrated Block for PCI Express Root Port model for simulation. The DS Port model in the simulation Testbench delivered with the Endpoint Block Plus Core has been replaced by the Virtex-6 FPGA Integrated Block for PCI Express Root Port model.
CR 510686: board.v contains incorrect work-around for 1-lane Verilog cores The issue with the board.v containing an incorrect work-around for 1-lane Verilog cores has been resolved by replacement of the DS Port Model by the Virtex-6 FPGA Integrated Block for PCI Express Root Port model.
CR 517672: Extra Start-of-frame signal generated on Receive Transaction Interface Issue resolved where the Virtex-5 FPGA Integrated Block Plus for PCI Express core generated an extra start-of-frame signal on the Transaction Receive interface (trn_rsof_n), without a corresponding end-of-frame (trn_reof_n) signal.
CR 525615: Core does not link-up when in a 2-lane configuration, on FXT / TXT devices Issue resolved where the Virtex-5 FPGA Integrated Block Plus for PCI Express core did not link-up when in the 2-lane configuration on FXT/TXT devices. See (Xilinx Answer 33421).
CR 522894: Syntax error in x1 board_dual.v causes simulation failures Issue resolved where comma missing from end of line 162 in board_dual.v.
CR 521843: MAP fails to complete due to predictable IP placement constraint issue Issue resolved where naming of module instantiation interfered with predictable IP constraints.
CR 506202: DSPORT drops completions with Byte Count field 64 or larger The v1.12 release replaces the downstream port with the new Virtex-6 FPGA Integrated Block for PCI Express Root Port model.
