Click the "Play" button at the bottom left to run the simulation. Power & Signal Sources:
The Simulation Log (bottom window) shows you timesteps, errors, and current usage. If a simulation runs "forever," you likely have a timing circuit (like an astable 555) intentionally oscillating—this is fine. If it says "Iteration limit reached," you have a wiring error (e.g., connecting VCC directly to GND). proteus 8 professional tutorial
Use Debug > 8051/AVR > Source Code to step through your C code line-by-line while watching the voltage levels change on the resistors. Click the "Play" button at the bottom left
