Hurry, how to use the netlist-based/spice-based spectrerf simulation.
Feb 26^th, 2020, 7:14am

Hi,

We are spoiled too much by Cadence, now I have no idea how to use the netlist-based/spice-based solution to simulation VCO by using SpectreRF. All of the tutorials from internet is graphic solution, I wonder who can give me an example with the netlist simulation, or any tutorial of the SpectreRF syntax in the netlist?
Appreciate very much.

Reply #1 - Feb 27^th, 2020, 12:34am See listing 1 in Simulating Switched-Capacitor Circuits with Spectre-RF. Or, if you are into Python and what to see an example of the whole process from generating the netlist, through simulating, to extracting and plotting the waveforms, see Flicker Noise -Ken

Reply #2 - Feb 28^th, 2020, 3:16am Hi Ken, I'm not sure why you changed the name of the voltage source from Vin to Vmod in runPnoise, but it breaks the simulation unless you also change the oprobe statements. Regards, Frank

I think I found the problem myself after a day or so and fixed it. Thanks for reporting it. -Ken
