I. Circuit board DESIGN steps In general, the basic process of designing a circuit board can be divided into three major steps. (1). circuit schematic design: circuit schematic design is mainly PROTEL099 schematic design system (advanced Schematic) to draw a schematic diagram of the circuit. In this process, to make full use of the various schematic drawing tools provided by PROTEL99, various editing functions, to achieve our goal, that is, to get a correct, beautiful circuit schematic diagram

. Next, designers can use the powerful features of Cadence PCB software in high-speed and high-density PCB design to complete their own design. If you have already done PCB layout in Protel, The script Function of Allegro can reproduce the

ibisVersion1.0 was launched for the first time in April 1993, and version1.1 was released after modification in June of the same year.Version2.0 was adopted in San Diego in, and upgradedVersion2.1 version, in December 1995 its version2.1 version became ANSI/EIA-656 standard, 1997Version3.0 was released in 62012. In of the same year, it was accepted as the IEC-1 standard and upgradedVersion3.1, the latest version of version3.2 was released in January 1999.IBIS is itself a file format that descri

Sinox, Macau, China many platform CAD graphics, PCB board, IC I know, HDL hardware description Language narrative, circuit simulation and design software, elemental analysis table, can open the eyes of the world.Recent research Sinox the implementation of Windows edition Protel,powerpcb,autucad, which is considered very cumbersome. On the other thought, Sinox the following in fact there are a lot of auxilia

High Frequency Circuit Wiring techniques in PCB Layout 1. Multi-board wiring High-frequency circuits often have a high degree of integration and a high wiring density. Using a multi-layer board is not only required for wiring, but also an effective means to reduce interference. In the PCB Layout stage, a proper select

General principles of PCB Board component layout:The general principles that designers need to follow in the layout of PCB boards are as follows.(1) Components preferably single-sided placement. If you need to place components on both sides, placing pin components on the bottom layer (Bottom layer), it is best to place the components one-sided. It is possible to

A. In accordance with the "first big after small, first difficult after easy" layout principle, that is important unit circuit, core components should be prioritized layout. B. The layout should refer to the schematic diagram, according to the main signal flow rules of the single Board to arrange the main components C. The la
