postlayout extraction -mentor
I am designing a fully differential amplifier, and found it is useless to take pre-layout simulation on the characteristics such as CMRR, PSRR, off set and so on, because in the schematic the two arms of the amplifier always matched well and the simulation result is always very good. So i want to take a post-layout simulation. I am using cadence virtuso tools.
Could anyone give some instructions on how to take a post layout simulation job, such as LPE,PRE, and so on. Is there any material about this topic?
thanks in advance.
