通过vcs去编译该c文件: 3. 在sv中想要使用cprog.c中定义的echo函数的地方,通过DPI机制导入,然后可以直接调用: 方案2: 将写好的c文件编译成共享库,在执行simv的时候通过 -sv_root -sv_lib 参数告知simv 共享库的路径 生成共享库方法如下: gcc-fPIC -Wall -c cprog.cgcc-fPIC -shared -o cprog.so cp...
文档连接中有一个版本的库文件和张强白皮书的代码,也可以直接去官网下载最新版本的库。 自己想放在哪里都行,只要记得这个位置就好,.tar.gz的文件用命令tar –zcvf filename 即可解压到当前文件夹,example_and_uvm_source_code中有两个文件,puvm是张强书的实验代码,uvm1.1-d是库文件。 ls –a就是显示所有文件,...

import "DPI-C" function string wallclock(); module try; //int unsigned t; string t; initial begin t = wallclock(); $write("time=%0s\n", t); end endmodule 如果需要更详细的自定义的时钟,那么可以先打通C语言的获取,然后再用SV调用。注意调用的格式正确性,而EDA工具有时候并不检...

Fix it in DPI-C code before running simulation. This error happens when trying the vlsi flow as I want to simulate my design. I use the command "make sim-rtl CONFIG=TinyRocketConfig BINARY=$RISCV/riscv64-unknown-elf/share/riscv-tests/isa/rv32ui-p-simple" as in the ASAP7 example ....
