基于FPGA的CPU仿真测试技术

CPU Simulation Test Technology Based on FPGA

随着计算机技术的飞速发展,在面向计算机系统结构教学实验的CPU设计中,软硬件的仿真测试十分重要。本文介绍了一种基于FPGA的16位CPU仿真测试技术,它利用FPGA内部的嵌入式阵列块单元构成指令存储器和数据存储器,将CPU的数据通路,控制通路单元集成在一起,提供一个完全的软件仿真环境。设计人员可以通过仿真软件结合FPGA器件直接进行整个CPU的功能仿真和时序仿真,最后结合泰克公司的TLA逻辑分析仪,对CPU进行全面的硬件仿真测试。

As the development of computer technology,CPU simulation test is very important experiment in computer system architecture courses. This paper introduces a new 16 bit CPU simulation test technology which based on FPGA device and logic analyzer. It provides a complete software simulation environment through building memory in the embedded array block , then integrate it with the CPUs data path and control path. Designer could make whole CPU function and timing test with the simulation software, then make hardware test and verification with Tektronix TLA logic analyzer.
