Dear guys,
I have a question about post-layout simulation. I am using a pdk in which a cap has its spectre but the resistor only has symbol. I create two simple circuit:
- circuit (1) only contains a capacitor (spectre)
- circuit (2) only contains a resistor (symbol)
I normally extract the parasitic of those circuit and run post-sim. The post-sim result of (1) is very similar with schematic sim. However, the post-sim of (2) is not.
I don't know what is different between spectre and symbol? And can I believe the post-sim of circuit (2)?
Please give me advice. Thank in advanced.
