vcs为什么makefile中执行的结果和直接执行的结果不一样
最近在使用vcs时,有需求需要批量仿真verilog代码,但是把在terminal中运行的command复制到makefile中,执行make的时候却发现报出许多错误.
原命令:

compile:
vcs ~/Testcase/RTL/7_VMC_5gate/tb_7_VMC001.v -debug_all -R

#VCS
export PATH=$PATH:/home/lindongyi/Synopsys_EDA_Tools/vcs2016/bin
alias vcs="vcs -full64 -cpp g++-4.8 -cc gcc-4.8 -LDFLAGS -Wl,--no-as-needed"
export VCS_ARCH_OVERRIDE=linux
说明:
代码功能不做解释了,更改前后命令的区别是,新命令多出来的参数是来自于安装vcs时,添加到.bashrc中的环境变量.
将.bashrc中vcs的参数添加到makefile中就可以得到和直接在终端运行一样的结果.
原因分析:
目前分析,可能makefile运行只调用.bashrc中的路径等内容,而不调用如alias这样的别名配置参数,所以需要手动将环境变量中的配置参数添加进来,才能保证makefile正常运行.
当然,如果makefile中的功能不需要.bashrc中的环境变量配置,那么应该与直接在终端中的命令行中执行是一样的效果.
收获:
以后在使用makefile的时候,就要主义是否在.bashrc中配置了alias,因为使用Linux中的Synopsys家的工具比较多,而这些工具在安装后,许多都在.bashrc中配置了alias,所以在makefile中使用这些别名的时候,出现报错就可以去.bashrc中把alias中的内容拷贝过来.
另外可以在终端中输入命令alias来查看有哪些别名被设置了.
alias命令执行结果如下:
