PSpice is the de facto standard for analog and mixed-signal simulation. Engineers rely on PSpice for accurate and robust analysis of their designs. Universities use PSpice as part of their electrical engineering curricula. Semiconductor vendors around the world provide PSpice models for their devices. Numerous books have been published on PSpice that span 10 languages! PSpice includes a powerful and robust simulation engine and works with Orcad Capture, Concept HDL, or PSpice schematics in an integrated environment where engineers create designs, set up and run simulations, and analyze simulation results.
