Hi Philippe

I have pasted below the log file I get when (a) the 2SC6144SG subcircuit Spice directive is not made a comment and (b) I ¡°OK¡± through the errors rather than cancelling the run.

Thanks for the correction to the .subckt. ?I got this from the On Semi website. Could this be a Spice D vs LTspice translation issue or just error?


Note I also found I had to alter their pin order in the line beginning Q1. They had:

Q1 2 1 3 ?C6144SG

But I¡¯m not sure why this should give me the issue I encountered when the Spice directive wasn¡¯t even being called upon¡­

Regards

Steve

Have you still the .log file you got when you tried to run the earlier schematic ?
