The PSpice Workshop

Course Description:

The purpose of this course is to introduce PSpice (aka Allegro AMS/Design Entry) to first-time users and to refresh seasoned PSpice users to the wide variety of analysis capabilities in the PSpice (Allegro AMS) simulator.

This 3-day course assumes the student has no prior knowledge of the PSpice circuit simulator and Capture schematic capture program. Everything necessary to fully build, run, analyze, design, and test circuits is presented.

Students should leave the course with a good understanding of how to apply PSpice to typical design and analysis problems.
