On the Combinatory Logic Circuit Design Based on the HDL

With the development and application of EDA technology, the electronics have experienced a revolutionary change. The desigh and implement of the mathematical and logical circuits with system class have been developed by the electronic engineers using advanced EDA tools such as VHDL and FPGA. The key points and difficulties of VHDL are explored by applied examples, different schemes of several typical composite and logical circuits compiled and validated by the software Max ＋ plusII are desighed, which can support a reference for the electronic engieers exploiting the mathmatical system.
