I received this reply from Mentor CSE after asking why the problem happend whling using metric-unit:
"The problem is that Valor expects data in inches, but when the data is in mm, the actual numbers are too large to handle, ie 99” is a lot more than 99mm"
We also use ODB++ Allegro inside for Allegro and output metric-unit ODB++ database, Valor Trilogy 5000's Netlist Analyzer performs well on this type of metric-unit database.
Now EE7.9.2 have eliminated this bug. Thanks for Mentor CSE in England, Engineering team and thank me.
