does icfb save $PWD when its launched?

hi,

i want to edit my .cdsenv so that it loads the PDK model files from my
local cadence directory rather than from the PDK folder, which is read-
only. first i tried setting the spectre.envOpts modelFiles variable to
"./file.scs" but it would still load from the default location, so I
changed it to "$PWD/file.scs" and it works. I just want to make sure
that using this way is ok because $PWD will change with any cd in
terminal. so far i have tried changing directory, closing terminal,
opening new terminals and it does not affect the $PWD inside cadence.
is there a better way to achieve what i'm doing? i don't want to put
the full path as i am also writing a tutorial for setting up the pdk
for new users and its easier to use this way than making everyone
write full paths.

thanks.

 

you might want to use any combination of these functions:

pwd()
getWorkingDir() ;;; same as pwd()
simplifyFileName()

use cdsdoc/cdsFinder for details on these functions

good luck!

 

Thanks, but can I use skill syntax in .cdsenv? I know it is possible
for .cdsinit. What I have now in my .cdsenv is the following:

spectre.envOpts modelFiles string "$PWD/file1.scs /path_to_pdk/
file2.scs /path_to_pdk/file3.scs"

/path_to_pdk/ is read-only. i need file1.scs in my local directory so
i can change the corners flag, the other two can stay where they are.
i asked my network admin and he said that although this works, it
isn't the safest way to do it because $PWD changes...

i tried setShellEnvVar("CWD=$PWD") in my .cdsinit but getShellEnvVar
("CWD") returns $PWD and not the actual path which sort of defeats the
purpose...

 

therefore use .cdsinit to do the job you want, using envSetVal() and
envGetVal() ... those two functions are the skill equivalency to
the .cdsenv syntax
