LTSpice IV, curious simulation problems
Hi, I encountered some curious simulation problem when simuating this circuit:
![Capture18-12-2015-14.44.15.jpg Capture18-12-2015-14.44.15.jpg](https://www.edaboard.com/data/attachments/58/58684-815ab77042b4877871d95569ffe19df7.jpg)
View attachment Inverter_6_stability.txt
Plot file: View attachment Inverter_6_stability.plt.txt
The error during simulation is (almost always) something like this:
while there is nothing wrong with the nodes named,and also the named nodes or op-amps can differ after I changed something completely unrelated to the circuit.
Also sometimes the error "... step too small" occurs.
Anyone any suggestions?
Thanks in advance!
