EDA technology as the development direction of electronic technology The traditional electronic technology includes analog electronic technology and digital electronic technology. In 1976, a single-chip microcomputer came out. As a very important branch of microcomputers, single-chip microcomputers have been widely used and developed rapidly. Has had a huge impact, but there are several major flaws in the microcontroller:
(1) The running speed is slow, and the single-chip microcomputer must rely on running one instruction. This serial mode is limited in speed. If multiple CPUs are used, the programming is difficult, the development system is expensive, and the software cost is high.
(2) There are many types of single-chip microcomputers, there are various general-purpose and special-purpose single-chip microcomputers, the selection is complicated, and the corresponding instruction system and language are also complicated.
(3) The reliability of the single-chip system is poor.
But designers often suspect their own design problems and do not doubt the problems of the microcontroller itself. For digital circuit design: it needs to go through several complicated processes such as Karnaugh map simplification and Boolean equation. Analog circuit design: its design is even more varied. The electronic design of the above three fields has its own regulations, and the design efficiency is low.
