The LogiCORE Endpoint Block Plus for PCI Express requires a license to generate and implement the core. There is no charge for this license.
To obtain the license, visit the product lounge at:
- ISE 10.1 SP2 design tools support
- Added FAST Functional Simulation model support for GTP
- Added a Dual Core Example Design for Virtex-5 FX70T
CR 454139: MTI Secure IP related Issue
Removed Xilinx_lib_mti.f from MTI flow as compxlib should account for compilation of unisim models for GT11 and SecureIP models for GTP/GTX and PCIe Hard Block.
CR 442552: Dual Core Example Design
Added a Dual Core Example Design to be generated for Virtex-5 FX70T only.
CR 458537: Tx Transmission Issues
Implemented a work-around for the "Tx Transmission Issues due to lack of Data Credits" Virtex-5 PCIe Block Restriction.
CR 469909: Update GTP wrapper
Update the GTP wrapper to remove TXBUFFERBYPASS mode.
CR 466714: Transfer of CORE Generator speedgrade option into delivered UCF
Issue resolved where the CORE Generator speedgrade selected was not being passed into the UCF.
CR 466393: PIO Example Design State Transition
Issue resolved where the PIO Example Design had an incorrect state transition in the TX state machine.
CR 467806: Added Fast Functional Simulation model support for GTP
Added Fast Functional Simulation model support for GTP.
CR 472100: Updated OOB_THRESHOLD values for GTX
Updated the OOB_THRESHOLD values for GTX as per latest recommendation for PCI Express Specification Compliance.
CR 472721: 8 lane product support for Virtex-5 LX30T
Issue resolved where support for the 8 lane product on Virtex-5 LX30T had been removed.
CR 472588: Receipt of Back to Back ACKs causing TX Lockup - 8 lane only
Issue resolved where receipt of Back-to-Back ACK DLLPs could cause the Integrated Hard Block to Lock-up in the transmit direction. This issue only affected the 8 lane product.
