Just for fun, this simple inverter oamp circuit:
*prueba del ADA4898
.load ./dio.so
.include ada4898.cir
v2 1 0 sin(0 0.1 1k 0 0 )
r1 1 3 1k
r2 3 4 20k
v3 6 0 dc 5
v4 7 0 dc -5
r6 4 0 1000
x1 0 3 6 7 4 ada4898
.print tran v(1) v(4)
.tran 0.01m 25m
.end
On gnucap: 0.719 seconds
Same circuit on QUCS: 65 seconds.
I do not understand why there is such tremendous time difference. Same
stop time, same step size. Gnucap goodness or Qucs badness....
Thanks,
Ramiro
