Discussion Topics • PSPICE Overview – Part 2: Schematic Entry in Capture • Guided Tour of Starting a Project and the Interface – Getting Started » New Project Wizard » Drawing a schematic and placing a ground » Overview of Simulation Types » Library Configuration (Symbol, Model, Include) – Common pitfalls

New Project Wizard • Most common initial pitfall • Need to select Analog or Mixed AD to get simulation option

Drawing Schematic • Project browser • Simulations and drawing templates

*. net • Netlist that describes interconnection to the simulator

*. lib • Text files holding libraries. • Every simulatable part must have a reference in a *. lib file

Part browser • Search only active for libraries highlighted in libraries window • Lower icons denote part templates available. • The PSPICE icon must be present here in order to simulate • Browse the libraries
