The SG3525 generates high-frequency signals. If your CPU gets overloaded, navigate to System -> Set Simulation Options and increase the time steps, or minimize other active graph windows.
The SG3525 is a voltage-mode PWM controller widely used in DC-to-DC converters, switch-mode power supplies (SMPS), and high-frequency inverter topologies. While you can find basic physical packaging symbols on CAD repositories, true simulation requires an active behavior model.
A SG3525 library accurately models the oscillator, the error amplifiers, and the internal flip-flop logic.
