Design of Pulse Tester Based on Eda Technology

Abstract

To apply Electronic Design Automation (EDA) technology in pulse measurement to promote the development of clinical diagnosis, the hardware platform construction and software design simulation of the pulse measurement system were mainly completed. For the design of the system, whether it was hardware or software, the modular design idea was adopted. The signal collection was mainly completed by HK-2000A integrated pulse sensor. After the signal was collected, it entered the system, and then it was analyzed by the main control chip, which also controlled the drive of peripheral circuits. The system software design was written in Very-High-Speed-Integrated-Circuits Hardware Description Language (VHDL), with a top-down design method. Firstly, the system was divided into the following six modules: frequency divider module, timer module, counter module, comparator module, dot matrix display module, count display module. Then, according to the functions implemented by each module, VHDL was used for design programming. Finally, each module was connected. The simulation results showed that the system design met the basic requirements. Therefore, the pulse diagnosis based on EDA technology is more intuitive and objective to collect and display human pulse information. The development and wide application of this technology will play an increasingly important role in promoting the development of medicine.
