Hi,
During SP analysis of LNA circuit (quite large netlist due to extracted views), the simulation is very slow. I could trace it to a file (sp.noise.sp) in psf folder, which I believe gets written after SP calculation at every frequency and hence gets very large in size(~2GB). What is the purpose of this file? Does it write noise summary of each instance in that file? If I want to simulate only noise figure and not care about noise summary, how can I avoid writing to such a file, and hence speed up my SP analysis?
SP stands for S parameter.
Thanks
