Hi, i am working on LM3409 and i have attached my TSC file. My simulation seems to run very slow. Is there any setting i can change to make it faster?5280.prac1.TSC

Hi Sneha,

Please try the following to speed up your simulation.

1. When I simulated the attached .TSC file on my system, it took ~10 minutes to simulate for 4ms. I tried changing simulation parameters. Increasing DC relative error from 1m to 2m changed simulation time to ~6 minutes in my system (roughly 40% reduction). You could try the same and see it it helps.

2. In case your system is multi-core, you can go to Analysis-> Options. Increasing the "Number of Threads" also increases simulation speed as system allocates more computing speed for the simulation now.

I hope it helps.

Thanks & Regards,
Abhisek
