@User Thank you for the video. This is an excellent starting point for setting up the Analog design environment. I have few questions regarding the spice model. 1. How is the formula for asd/ psd is derived? (what is significance of 0.29 number in the formula?) 2. Will the same spice model applicable for post layout simulations? I believe in post layout simulations actual area and perimeters are extracted by RC tools and back annotated them into the simulation.
