Hi,
I am generating calibre view file from calibre PEX for extracted simulations. However, my extracted and non-extracted simulation results for low noise amplifier show a huge gain loss of 15dB. After manually analyzing the layout parasitics, i think that such big loss is not possible from just layout parasitics. I assume that i am doing something wrong in layout parasitic extraction. I read somewhere about the importance of 'lpe' flag in calibre extracted view generation. It is normally used to avoid device model parasitics to become a part of extracted parasitics. Can somebody tell from where in calibre PEX i can change 'lpe' flag setting.
