Hi !
I can create model TL494 but simulation stopped in a few moments:
"Fatal error: Could not open file “ltc.lib” if delete this line:
"Fatal error: Could not open file “UniversalOpamps2.sub” - if delete this line:
Fatal error: No such subcircuit: LEVEL.2 "
Any help ?
Model TL494 from mkdynamics web:
