design

automatic

) that is, electronic design automation. EDA in the traditional sense refers to the system design of FPGA and CPLD. Broadly speaking, all electronic system designs tend to be automated. After all, technology is developing rapidly.

For the design of digital stopwatch, in university courses, it is generally to learn digital circuit and EDA first, and then to learn the course of single chip microcomputer, because it is the inheritance of digital circuit, and EDA design is the beginning, and then the design of single chip microcomputer begins.

My personal opinion:

From the cost point of view: 1, giving priority to the scheme of 5 1 single chip microcomputer+digital tube;

2. Digital gate circuit+digital tube is adopted; 3. Built by CPLD/FPGA+ digital tube. Because FPGA/CPLD is still relatively expensive, MCU chips and gate chips are relatively cheap.

In terms of system reliability and speed: 1, FPGA/CPLD；; Is the first choice;

2, digital circuit door construction;

3. Realization with single chip microcomputer; The use speed of FPGA/CPLD is very fast, which is realized by hardware, and the single chip microcomputer is realized by software.

From the perspective of system upgrade: 1, giving priority to FPGA/CPLD；; ;

2, single chip microcomputer realization;

3. Gate structure;

If the system is expanded and upgraded, the gate circuit is very difficult and can only rely on the scheme of 1+2, which is convenient, fast and easy to debug.

If you are a student, I suggest you learn everything, which is the foundation of the foundation.

If you think it is good, accept the recommendation!
