Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. If you have many questions of PCB Design, please come here!

Simulation is an essential link in the process of PCB design. PSpice is a simulator provided by OrCAD PCB design software. Coupled with work flow of OrCAD Capture, PSpice provides a fast trailer prior to board design in order to increase PCB manufacturing efficiency and ensure the final performance of PCBs. Cooperation between OrCAD Capture and PSpice is displayed in Figure 1 below.

BTW, four elements have to be known prior to design simulation, which are listed in the following figure.

Analysis types PSpice can be applied to perform include DC analysis, AC analysis, transient analysis and advanced analysis. Each type of analysis contains their own analysis types that are shown in the following table.
