[调查] dc_shell-t initialization error

[复制链接]
发表于 6 天前 | 显示全部楼层 |阅读模式
When I ran the "dc_shell-t" in local directory after copy "synopsys_dc.setup" to local directory, I got the following messages:

I found these errors were caused by two commands in .synopsys_dc.setup:
source $synopsys_root/auxx/syn/.dc_common_procs.tcl
source $synopsys_root/auxx/syn/.dc_procs.tcl

But the .synopsys_dc.setup file in my working direcory is the original one which synopsys provided. How can I avoid these error messages?
