order of .Synopsys_dcsetup files

[asic_learner]

Hi,

In what order are .Synopsys_dcsetup files picked up and why?

 

[tdminion]

1) Synopsys root directory
2) your home directory
3) current working directory

reasons for the order should be obvious....

The below is assuming that dc has been setup properly. And dc_shell is available in the env.
