SPI-3 Link Layer v7.2 - TSX missing for first address out of TDAT on Virtex-6 and Spartan-6 Devices

描述

When targeting Spartan-6 and Virtex-6 devices using  the SPI-3 Link Layer Core v7.2 and earlier, TSX is missing for first address out of TDAT.  This error appears in Spartan-6 and Virtex-6 FPGA functional simulation where the first address sent out on TDAT should be accompanied by TSX. This TSX pulse is missing. This shows up in simulation as a single RDAT/TDAT mismatch when the first Tx packet is received on SPI-3. No other mismatches occur. 

解决方案

This issue has been fixed in v7.2 rev1 of the core available as a patch for download, see (Xilinx Answer 35141).
