Status / Summary
------------ Momentum Simulation -----------------
Version: Momentum MomEngine 7.0 (*) 2008.500 Jan 22 2008
Simulation mode: RF
Design: transline
Simulation started on : Tue Dec 09 11:13:16 2008
Substrate calculation started
The simulation can not be conducted sucessfully. Does anybody can tell me how to resolve this problem. Thks.
