Hi everybody!
I am using Synopsys HSPICE to analyze a circuit and I have a problem with the HSPICE parser for back-annotation.
I have specified the spef file for the circuit it gives me the error "unfound instance" for each element of the HSPICE netlist. For example in my netlist I have the element:
then in the SPEF file I have the net definition:
and the error is:
I don't know how I have to write the hspice netlist in order to make it match with the parasitic information.
Is here somebody who can explain me how to do that, please?
Thanks!
