I was wondering if someone could provide a comparison of what a pre extraction netlist and a post extraction netlist (with just RC extraction) in terms of the number of parasitic elements that are present in the post-netlist.
Using a certain foundry, we found that the post-netlist had several hundred parasitic elements more even for simple circuits (consisting of less than 10 transistors).
Using another foundry we found that the post-netlist had just may be less than 10-20 more parasitic elements.
I am wondering why there is such a big difference (both process have same geometry, nearly same number of mask layers )??
Thank you in advance
