LTSpice VS. PSpice

See why engineers choose PSpice over LTSpice to get past the noise and simulate critical circuit functionality for first-pass design success.

Compare for Yourself

Don’t let software limits hold you back. Be sure you are working with state-of-the-art software capable of keeping up with your design demands. PSpice quickly evaluates, optimizes, and ensures the reliability of your designs– before prototype. The advanced simulation capabilities in PSpice enable you to solve complex design issues quickly and meet your performance goals on the first pass. 

Take your design capabilities to the next level

Free can come with a cost if you don’t have access to the capabilities you need. PSpice has simulation capabilities you just can’t get in LTSpice including:

  • Performance Analysis
  • Optimization
  • Smoke Analysis
  • Monte Carlo Analysis
  • Sensitivity Analysis
  • Electro-Mechanical Co-Simulation
