@REM 生成iverilog编译文件
@REM -s (topmodule) (topmodule file) 用于指定顶层模块
@REM -c (filelist) 用于指定编译文件
@REM iverilog -s %MODULE_NAME% %MODULE_NAME%.v
iverilog -o %MODULE_NAME%_%BUILD_TIME%.out -c%WORKSPACE_DIR%\filelist.icarus

@REM vvp生成仿真文件
@REM -n (source iverilog build file) 表示非交互模式启用vvp 
@REM -l (log file) 表示生成log到文件中
vvp  -l vvp_sim_%BUILD_TIME%.log -n %MODULE_NAME%_%BUILD_TIME%.out
