I want to see the efect cgsoverlap and cgdoverlap capacitances have on a design I'm working on. I don't know how to go about changing model parameters for a schematic netlist or a extracted netlist and resimulate the design. When I look at a spectre netlist I only see the following parameters:
M10 (ONB GATE_B OUTB AGND) nch3 l=350.0n w=420.0n m=1 nf=1 sd=540.0n \
ad=2.016e-13 as=2.016e-13 pd=1.8u ps=1.8u nrd=0.642857 \
nrs=0.642857 sa=480.0n sb=480.0n sca=0 scb=0 scc=0
But I can see from here http://www.seas.upenn.edu/~jan/spice/spice.MOSparamlist.html that CGSO and CGDO are in fact mos parameters. Why aren't they editable here?
At this point I wonder if CGSO and CGDO are editable for an extracted specre netlist from Assura QRC?
If I delete/edit the parasitic capacitor on this netlist, would that achieve what I'm trying to do?
c65 (GATE, SOURCE );
