Why am I experiencing errors in the Compilation Summary when I run Compxlib for ISE 10.1 and ModelSim 6.3E?
There is a known issue in compxlib where it handles the keyword ERROR as a compilation error and falsely reports it in the Compilation Summary. Check the compxlib report to see if there are any warnings with the keyword error, and when you count them up it should be equivalent to the number of errors reported.
This issue is fixed in 10.1 SP1.
NOTE: There might also be other legitimate errors due to environment setup, so please review the compxlib report before ignoring any errors.
