OrCAD is one of the most complete and best applications you can find for designing professional electronic circuits, letting you automate those circuits, and generate schematic simulations of all types.
With OrCAD you can fix the temperature and other atmospheric elements of the circuit, with the aim of making the simulation totally real. The program pack which OrCAD comes equipped with includes the following: OrCad Capture, OrCad Layout, OrCad PBC editor, OrCad Pspice, OrCad schematics, OrCad Sigxplorer and Specctra for OrCad.
With the help of OrCAD you can generate all types of designs: schematics, digital/analogue/hybrid of both simulations, FPGA, CPLD, design synthesis, printed circuits, hierarchic designs, etc. You can use variable electrical components, individually work on each part of the project and optimize certain designs to reduce costs. OrCAD can also do topological analyses, scale to any size, take personalized screenshots of project fragments, and much more.
