Maybe we have to use my patch with some other directives ($config and
$if for example). Indeed, following example doesn't work as expected :
.param ac=0
.options method=gear reltol=1m minbreak=200ps
.if (ac==1)
.ac dec 1000 1 1MEG
.control
run
.endc
.else
.tran 1u 100m 0 1u
.control
write results.raw
run
fourier 1k v("/VS+")
fourier 1k v("/VS-")
quit
.endc
.endif
Both .control/.endc blocks are run by ngspice. That's being said only
.tran is reached ;-)
Best regards,
JB
