SPI-4.2 v9.3 - SrcTriStateEn does not tri-state TDClk

Description

Known Issue: v7.x, v8.x, v9.1, v9.2, v9.3

The SPI-4.2 core User Guide indicates the SrcTriStateEn input to the Source core should tri-state TDClk, TDat[15:0] and TCtl. However, when this signal is asserted, TDClk is not tri-stated.

Solution

A patch for this issue is available to install for both the v9.3 (available in ISE 11.3 and 11.4) as well as for v9.3 Rev1 of the Core, available in ISE 11.5.

Important Note: There are two distinct v9.3 Rev1 Cores available. Please see (Xilinx Answer 33313) for more information on this. Only install Rev1 from the AR if you have ISE 11.3 or 11.4. Only install Rev2 from this AR if you have ISE 11.5.
