Dear Friends, I am using assura DRC and LVS. However, Assura can not be started. The error message in CIW is: ibmPdkRunAssuraDRC() *Error* eval: undefined function - vuiDRCRun <<< Stack Trace >>> (... in ibmPdkRunAssuraDRC ...) ibmPdkRunAssuraDRC() ERROR The version of Cadence icfb and Assura are the right ones. What could be the reason of this problem? Thanks,
