Hi folks, I have a problem with the tool assura. I have setup the files with the right path. And when I try running a drc-run the following error is show: ************* *WARNING* vdba: vdbInitVDBA called but VDBA already initialized Loading tech rule set file : ~bormann/work1/ASSURA/techRuleSets Compiling rules... *WARNING* Failed to build VDB. Cannot submit DRC Run. ************* and the drc is aborted. What is wrong? Any ideas? There are any log-file more then CDS.log? best regards Stefan
