I apologize for the inconvenience. i am using virtuoso IC6.1.5.500.16.2 let me ask through an example: I have two signal and want to subtract them to get difference. Signal 1 is reference signal without noise signal 2 is signal with noise. Subtracting both will give only noise. I have to run transient simulation two times on same circuit. one time without noise (ref signal) second time including noise. (signal with noise) i appended the two results. but when taking the difference it says "the output xyz does not exist" (xyz is the first transient simulation result). i also tried with both schematics in: - same cell view -in different cell views -in different libraries but issue is same. I want to know how can i hold the previous simulation results? kind regards zubair![]()
