Electrical and electronic components will be put on drawings. Set the work environment is to use the menu Design / Options and Tool / Preferences for painting schematic drawings of the environment settings including size, capture grid, electrical grids, templates and other settings. Schematic design environment is to draw the preliminary work, in the schematic drawing, you should set the design environment. (1) set the schematic design environment.
The above schematic design process, SCM minimum system schematic design process is as follows: Schematic design of the most basic requirement is correct, followed by the rational layout, and finally re-layout is correct and reasonable under the premise of the aesthetics and readability sought. Usually printed circuit board design flow shown in Figure 2.įigure 2 printed circuit board design flow chartįollowing minimum system mainly to illustrate the design of the circuit design of Protel 99SE specific application. Therefore, the printed circuit board design is the most important and crucial step.
Printed circuit board design from schematic to become an important step in a specific product, printed circuit board and directly related to the actual product.
Schematic design flow shown in Figure 1.ġ.2 printed circuit board design and process Schematic design is mainly to draw a correct and perfect circuit schematics, circuit schematic drawing of the whole circuit design. At the same time, Protel provides an open database maintenance environment, users can easily modify the original device models, you can also create a new device model.ġ.1 circuit design and schematic design processĬircuit design is to achieve a real electronic product from concept design, circuit design to physical design of the entire process. Protel provides more than 20 analog and digital device simulation component library, contains a total of more than 6,000 commonly used components. Protel for each type of analysis provide a set of setup parameters, through the Settings dialog box can easily set the parameters required.
Protel circuit simulation software has the powerful ability to achieve analog / digital mixed-signal simulation analysis can provide a continuous analog signals and MF10CCN suppliers and discrete digital signal simulation, and can analyze all aspects of circuit performance, such as cross-circuit DC characteristics, temperature drift, noise, distortion, tolerance, worst case and other features. This article focuses on the Protel software in the electronic clock circuit design.ġ Protel software design characteristics and MF10CCN price and process
Protel 99SE was launched in 2000 based on Windows platform, the sixth generation of products, its main function modules include circuit design, schematic design, printed circuit board design, packaging component design, circuit simulation and MF10CCN datasheet and so on. Since 1991, Protel has become the first choice for the majority of circuit design software designers.
Protel is a set built on the PC environment EDA development tools. Electronic design automation EDA (Eleetronic Design Automation) has become an irreversible trend. With the rapid development of electronic industry, LSI applications are increasingly common.
