Simulation and design of the code-decode circuits in PI-BIU interface unit chip based on Verilog

Verilog HDL is a specialized language for the description of hardware. It has widely application in circuit designing. The design description can be supported by different tools and simulated by different devices. PI bus conveys datum among multi-parallel-job modules. It is because of better compatibility, real-time and reliability that PI bus is usually used for the interlinkage of multi-parallel-job modules in multiprocessor system. As an example, the implementation and design of the code-decode circuits in PI-BIU interface unit chip based on Verilog language in this paper. It presented some thought on the application of EDA in these circuits and the methods on Verilog HDL.
