以前在学校里的课程设计，使用verilog编写的一个CPU程序，可以下板子-Ago in the school curriculum design, the use of Verilog CPU prepare a procedure under the board

说明：  VHDL语言100例详解。详细讲解了用VHDL语言进行数字电路和数字系统设计的知识。用100个实例，不仅进行基础的门电路设计，而且还有较为复杂的数字系统设计。这些实例可以直接被调用。(VHDL Elaborates on 100 cases. Detailed account of VHDL for digital circuits and digital systems design knowledge. With 100 examples, not only for infrastructure gate design, but also more complex digital system design. These examples can be called.)
