Dear all,
I got a problem while doing the parasitic ext for an op amp.
The complete amplifier layout was DRC clean and passed the LVS check.
I also did RCX extracation for all the sub-blocks of the op amp. The
extraction mode was set to "RC". Everything's fine. However, when I
tried to run RCX for the complete layout, I got the following errror:
*FATAL* at "rex": res command file error - imcomplete. (the last part
of the log file which shows this error was attached below). But if I
changed the extraction mode to parasitic capacitor only, I can
successfully get the ext done. Could anyone point where the problem
is? I'm running Cadence 5.0.33 with Assura 3.1. Thanks much!
Jay
