Chipscope Pro - problem exporting vcd from multiple ILAs

Hi,

I have a design where I've had to use 2 ILAs to capture the signals I require to debug an issue. On the first ILA (ILA0) , I can export a VCD file to view in an external viewer. If however, I export the trace from the second ILA (ILA1) the VCD viewer tool complains that the format is not correct. I've tried several vcd viewers. wave v1.12 says that Bad VCD file format, parse failed and it quits. GTKWave Analyzer v1.3.19 complains that there are  "no symbols in VCD file..is it malformed?  Exiting!".

 

Anyone have a solution or workaround?

 

Regards

Enrico
