Hi,
I want to do the parasitic simulations of my circuit in cadence. I used calibre PEX tool to generate the extracted view, However, as the circuit is quite big, the extracted view simulations are taking very long time. Moreover, sometime the software crashes while doing the extracted simulations. Is there any way that i can only insert the critical parasitics in the main schematic and run the simulations (rather the using calibreview file from calibre PEX). What will be the right way to insert critical parasitics. For example, in distributed model format or lumped format. i.e should i put the overall resistance of lets say vdd path as one resistance or divide it into small pieces with parasitic capacitance to ground in between.
Looking forward for your suggestions.
