At present, there are many EDA software on the market, and these softwares also contain a certain component library. Protel is currently the most convenient, fast-moving, and user-friendly interface in the EDA industry which can provide the best service for Component Graphic Parameter Analysis. It is also the most used EDA tool in China. It mainly consists of two parts: the printed circuit board schematic design system.
Protel 99 has built a library of components for many companies’ electronic components. These components are stored in different component libraries according to their company; on the other hand, in order to facilitate the pcb board designers to select common components, Protel 99 uses many common components and collect most commonly used component into a library called miscellaneous Devices.ddb, when drawing the circuit schematic diagram to find the required resistors, capacitors, inductors, diodes, transistors and integrated circuit module diagrams, you must first load the corresponding component library.
In Protel DXP, the component library consists of three types, namely the integrated library, the schematic component library and the PCB closed library. The integrated library is a component library form that closes together the schematic symbol of the component and related PCB pin distribution, SPICE simulation model, signal integrity model, etc. The file extension is InLib.
In Protel DXP, when a custom library is loaded and the schematic symbol is called, all relevant information about the component is called simultaneously. The PCB package library defines component shape and pin assignment information with a file extension with the name of PcbLib.
A schematic component library is a library of component symbols used to express design intent when drawing schematics.
Its file extension is SchLib. Protel DXP provides users with a rich library of components, including almost all component types of electronic component manufacturers, ensuring that designers can find most of the components in the component library.
