Hi there, does anyone know why some symbols like launcher.sym, lab_pin.sym, etc are missing while opening the test schematic of gf180mcu pdk

Where did you install gf180mcu from?

From volare

ok so may be someone from efabless may answer. It's probably a configuration issue. What do you get if you run xschem from the terminal and at the xschem prompt type:

foreach i $pathlist {puts $i}

Its working if I create a softlink to xschem_library/devices in my pdk directory

Stefan Schippers

yes this is a configuration issue, there is a

/usr/local/share/xschem/xschem_library

path. This means that lab_pin.sym in a schematic will be placed with a reference name as

devices/lab_pin.sym

, since concatenating the path and

devices/lab_pin.sym

gives the true filename. However if the objects in the test schematic do not have

devices/

before the symbol name you need to change the path to

/usr/local/share/xschem/xschem_library/devices

. Creating a link does also work since the current directory will be searched. However its better to fix the path in the xschemrc.

Schematic does have devices/ prefixed in their reference name

But ig its checking only within the second directory

Stefan Schippers

then please check if `/usr/local/share/xschem/xschem_library/device`s does exists and symbols are present there...

it joins devices/ in reference name with pdk/.../gf180mcu_tests rather than pdk/.../xschem(which is in the path) to give the true filename

try to do

ls /usr/local/share/xschem/xschem_library/devices

at the xschem prompt. is the directory accessible from xschem?

z-a-p-k-i-n-g

01/21/2023, 10:34 AM

Nope its not able to access it

Stefan Schippers

01/21/2023, 10:41 AM

ok this is the reason. xschem is probably running in a sandboxed container. You need to be able to access /usr/local/share/xschem from within the container. But i am not using containers, so I hope some efabless guys kick in...

try to put the issue in #gf180mcu I think most of the people now use this pdk through volare.
