When I enter dc_shell-xg-t, I found the parameters (like $link_library) is loaded as I used before.
How to clear all the parameters (like $link_library) in Design Compiler dc_shell-xg-t?
BTW, can I source .synopsys_dc.setup after I enter dc_shell-xg-t?
if you are defining link library then use remove_lib else unset link_library.
Give synopsys_dc.setup as diff name i.e. Synopsys.tcl and then source it.
