No time for 555

Post by diffequ »

Greetings Everyone,

I am running ISIS Release 7.04.02 SP2 (Build 6564) and I created a simple 555 timer circuit. It so happens I get the following error message when I try to run the emulation:

[SPICE] Gmin step [43 of 120] failed: GMIN=1.6156e-005
[SPICE] Gmin stepping failed
[SPICE] Source step [0 of 120] failed: source factor = 0.0000
[SPICE] Too many iterations without convergence.
Real Time Simulation failed to start.

Can anyone tell me what I am doing wrong?

Thank everyone for reading the above request.

Sincerely,

diffequ

Label the wire on the pin TR with IC=0.
