Problem Title:
--OBS--Timing Analyzer: Failed to open document when analyzing paths
Problem Description:
When analyzing paths in the Timing Analyzer, an error sometimes occurs stating: Failed to open docum
ent. This can depend on the amount of paths analyzed per timing constraint chosen in the report opti
ons.
This issue is related to the size of the file generated by T.A.
It appears to be fixed in M1.4 for all but the Windows '95 version.
Solution 1:
solution 1:
A document is saved in the windows\temp\ dir. However this is often empty.
Solution 2:
You can run T.A. and a "command line" mode by opening the Console window from the
View menu. Here you can issue an "AnalyzeAllPaths", or "AnalyzeDesignPerformance"
command etc which equates to the "All" and "Mhz" toolbar buttons etc. How does this help?
Well there is an extra option to the command line that allows you to save the timing report
to a specific file rather than view it. So you can then open the file in an editor. An example
command line is:
AnalyzeAllPaths save c:\temp\timing.twr
or abbreviated to
aap s c:\temp\timing.twr
