OrCAD PSpice A/D Reference Manual.pdf

OrCAD offers a total solution for your core design tasks: schematic- and VHDL-based design entry; FPGA and CPLD design synthesis; digital, analog, and mixed-signal simulation; and printed circuit board layout. What’s more, OrCAD’s products are a suite of applications built around an engineer’s design flow—not just a collection of independently developed point tools. PSpice and PSpice A/D are just one element in OrCAD’s total solution design flow.
