When I try to import a .twr report into PlanAhead, generated by TRCE command line, I obtain the following error:
"ERROR:importing trce results: No valid paths found for displaying."
There are errors in my report. Why is this happening?
This is a known issue with PlanAhead where it gives the errror when importing the summary report (.twr) generated by TRCE command line.
An example for the TRCE command line would be the following:
trce.exe <design_name>.ncd <design_name>.pcf
There are 2 ways to work around the issue:
1. Generate a .twr report using the Timing Analyzer GUI, and then import the results into PlanAhead.
2. Generate a .twr using the TRCE command line using the -e switch:
eg trce -e <limit> <design_name>.ncd <design_name>.pcf
For more information on TRCE command line options, please refer to the Development System Reference Guide at http://toolbox.xilinx.com/docsan/xilinx10/books/manuals.pdf
This issue will be fixed in the 11.1 release of PlanAhead.
