Tool/software: TINA-TI or Spice Models
I got the error "Irregular circuit" when simulating in TINA a circuti based on the Spice model of LM3485.
Error and circuit can be seen in the attached screen shot.
Macro model anexed as .pdf (original model imported from TI website, erased the startup model).
Does anyone know the cause?.
Thanks.
Hi, Please go to Analysis ==> transient ==> and choose either "Zero Initial values" or "Use initial Conditions" . I simulated your circuit and it runs with no error with this modification.
