9.1 Chipscope Pro: When I use Chipscope Pro Analyzer and XMD on a Platform USB cable, I get Corrupt data in my ILA

Description

When using Chipscope Analyzer combined with XMD 9.1 one after the other in my design the Data captured in my ILA looks like it has been corrupted. The symptom is that all "1's" appear on all channels in the trace followed by valid data. Is this an issue in my design or a Chipscope issue?

Solution

This issue results from handshaking problems between XMD and Chipscope on the Platform Cable USB. The issue is resolved in EDK 9.2. To work around this issue, use Parallel Cable IV.
