# LTspice Transient Analysis Simulation error

I am simulating a boost converter, however LTspice is telling me the transient analysis is only 13.8 % done, as seen below. Why is this?

• Why do you think it's wrong? You asked for 5 ms, and only got ~0.7 ms. 13.8% of 5 ms is 0.69 ms. – The Photon Nov 24 '19 at 0:33
• @ThePhoton the simulation is not running all the way to its steady-state. – Hector Nov 24 '19 at 1:15
• What's inside the pwm and gate driver blocks? – The Photon Nov 24 '19 at 1:42
• Try setting Rser=10m to the output capacitor, and also to the V_driver_supply. Try adding a small 1...10p cap from node c to ground. The custom models might also be to blame, as @ThePhoton mentions. – a concerned citizen Nov 24 '19 at 17:21
