1000 Threads found on edaboard.com: Run Spectre Simulation Cadence
I have a downloaded a PSpice model file (in .lib) from On Semiconductor.
I am wondering how to run spectre simulation in cadence with this file. For the same diode, there are .sp2 and .sp3 models are available as well. Am I using the right one (.lib) for spectre simulation?

If you use hspice simulator(you can choose simulator in cadence enviroment if you have such license), you can run simulation directly with hspice model. Otherwise you need spectre model, which is quite different format from hspice.

I designed a comparator in a transistor level.
I connected the comparator to a digital logic gate, like inverter or AND gate from the NCSU_Digital_Parts.
But whenever I use the logic gate, It gives me an error.
My question is,
1. Can I use digital logic gate in spectre simulation?
2. How can I fix this error message?
