摘要
基于软硬件协同设计技术提出了基于系统的模拟仿真和调试方法 (SSED) ,其基本思想是 :在模拟和仿真时建立真实的运行环境 ;利用可重定目标编译器和汇编器生成器将 C应用程序转换成汇编语言、执行代码及模拟和仿真的输入向量 ;利用时间模型进行汇编级调试 ;对运行结果进行分析 .利用该方法设计 Jbcore16的过程说明 ,该方法可进一步加速处理器的逻辑验证 。
Based on hardware/software codesign, a new kind of system level simulation, emulation and debugging method(called SSED) is proposed, which can be conveniently used in processor design. This method can be described as follows: set up execution environment according to real world applications;translate C program into assembly program, execution code and input vector which is used in simulation and emulation; debug VHDL program with assembler program under a kind of time model; analyze the execution results. The design and implementation of Jbcore16 processor indicates that SSED can increase verification efficience and accelerate processor design and implementation speed.
