I'm Luca. I'm searching to simulate a voltage mode PWM power supply using TL494. I tryied to work with SG1525A but that model request modification into the netlist and into the .option.
I also found the way to create a PWM controller from Christophe Basso's literature but now I haven't the time to work on it. Could you inform me about the use of the spice models or provide me them.
