Hey all
While simulating some current-mirror circuits, I got stuck on some weird
error... I don't know if this is a bug, non-implemented or just some
stupid mistake of myselve ;)
Below I pasted the error and my circuit. I tested this on gnucap 0.33 on
a debian and a gentoo machine.
#Time I(Rl)
did not converge
0. -0.071605
very backward time step
convergence failure (itl4)
zero time step
internal error: step control (adt=1e-12,rdt=-6.10352e-13)
time0=2.2207e-12 time1=1.2207e-12 rtime=6.10352e-13
This is my circuit:
address@hidden:~/ef$ cat ef.ckt
Emitter Follower
.include ca3046.mdl
Vcc 66 0 10
Vee 0 99 10
Vs 11 0 SIN(0 1 1k 0)
Q1 66 11 13 0 CA3046
Q2 13 12 99 0 CA3046
Q3 12 12 99 0 CA3046
R1 66 12 199
Rl 13 0 100
.print tran I(Rl)
.tran 0 2e-3 1e-6 > ef.dat
