OrCAD PSPICE produces too many important *.* file extensions.
Can you please describe or detail the each type file and what for it stands?
OrCAD PCB Designer with PSpice includes all of the capabilities of
OrCAD PCB Designer as well as the PSpice circuit analysis and
simulation capabilities. This sophisticated, native mixed-signal
simulator performs functional simulations of digital parts and allows
engineers to perform a broad range of PSpice analyses. Tight
integration with OrCAD Capture facilitates rapid design-and-simulate
repetitive cycles allowing engineers to explore various design
configurations before committing to specific implementation.
