hello!
It has been almost 3 decades I am using LTSPICE, never , not even once, had I ever come across a test bench not work!
A bit of the history
- upgraded to latest w10 version of LTSPICE VII ( I think)
- it took several hrs( done over night, ??)
Then wanted to model & simulate a circuit using LT1713 ( upon search, it came up as the fast comparator)
Then selected a current feedback amplifier LT6559.
With a few other parts, got a new schematic done & ran the simulation.
zippo. Key waveforms not computed ...
Naturally, you suspect I did not follow the instructions for using the comp or the amp.
so I opened the comparator "Test Bench".
Lo & behold, the test bench does not run as expected!
So went & checked if the upgrade worked properly...well, it does.
I am not uploading the comparator test bench.
Any idea what is up with this model?
appreciate any help in figuring out what is wrong here.

PS: Helmutt Sennenlwald still here?
