I have a customized electronic model for my circuit input. This model contents some resistor larger than 'rcut' which is now equals to 1e12 Ohm in my cadence setup.
I guess this limit can be changed. But I couldn't find where to change? Any body has expirences on this?
I found the rcut option in spectre reference manual. And tested with for example add something in the option for each analysis:
which should be large enough for our model. But as you said, the result has nothing changed.
