spice command
Hi,
how to calculate circuit DC point with spice?
usually i use tricky method - like this:
Here i start variation of mock dc source (VV_VAR) in order to get value of interm voltage and power consumption.
Any suggestions?
(i feel this method is not very good from the point of performance)[/code]
Added after 53 minutes:
it seems like using
.OP
directive instead of
.DC
will help. can't test it since my spice simulator do not provide saving operation points... searching for alternative simulator.

.lib ./lib/L130E_HS12_V241.lib TT
MM1 VDD VDD interm VDD P_12_HSL130E L=0.120U W=1.000U
MM2 interm VDD VSS VDD P_12_HSL130E L=0.120U W=0.820U
VVDD VDD 0 1.2V
VVSS VSS 0 0V
VV_VAR VAR 0 1.2V
.measure DC I avg i(VVDD)
.measure DC V avg v(interm)
.DC VV_VAR 0 1.2 1
.end
