Fehlinterpretation !
Die alte Version läuft mit Krücken.
Damped Pseudo ist er dazu gekommen. Gmin stepping macht teilweise Problem weil er in zu kleine Zeitbereiche abdriftet, da gehen paar Interationen nicht auf.
Hintergrund ist wohl die genauere Umsetzung von Level 3 Mosfet Modellen, welche teilweise die Simulationen ins Nirvana schickt.
Und wenn man mal in die Changelog.txt schaut ... die Fehler werden

Die letzten zwe-drei Monate und ich hab die Banalitäten und LT Modellanpassungen raus genommen.
Alternativ mal mit der original PSPice Engine (OrCad) arbeiten ... da läuft aus dem Stand kein Schaltnetzteil.
Aber gut ...
