本实验是VHDL的触发器实现，将基本RS触发器，同步RS触发器，集成J-K触发器，D触发器同时集成在一个CPLD芯片中模拟其功能，并研究其相互转化的方法。-This experiment is the trigger of VHDL realize, will be basically RS flip-flop, synchronous RS flip-flop, the integrated JK flip-flop, D flip-flops simultaneously integrated in a CPLD chip to simulate its functionality, and to study their mutual transformation approach.
