@Stefan Schippers How do I manage to modify my schematics so I'm able to share it between computers and they go with correct symbol path. Every time I place my schematics on another PC I need to alter the path. I'm using all the tools in a local installation , with GF180mcuD (latest) and my

.xschemrc

is attached. All tools are updated to the last version

Make sure that your symbol directory is in your

XSCHEM_LIBRARY_PATH

path. For example, if all your symbols are in

~/xschem/symbol

directory, add this line to your

xschemrc

. (If there is a

xschemrc

file (no leading

.

) in the current directory, it is used instead of

~/.xschemrc

. This makes things a bit more portable).

append XSCHEM_LIBRARY_PATH :$env(HOME)/xschem

and then update all your schematic files

find ~ -name '*.sch' -exec sed -i.bak "s,$HOME/xschem/symbol,symbol," {} ¥;

This will change all your absolute references to relative references and should make the data portable.

Thank you very much!

If you have a schematic with absolute paths, after setting up the xschemrc with the list of paths in

XSCHEM_LIBRARY_PATH

as @Mitch Bailey wrote you can simply open the schematic and force-save it again (ctrl-save-s), it will be saved with relative paths, and should be portable. See this man page. You should add to

XSCHEM_LIBRARY_PATH

all directories used for schematics/symbols in your design, so no element is saved in the schematic file with full (unportable) path. The syntax of

XSCHEM_LIBRARY_PATH

is a list of (absolute) paths separated by :. Usually when you start a project you create a directory and place an xschemrc file into that directory and start xschem from that directory. This allows you to have different projects that use the same or different pdk data. If an xschemrc file is found in the directory where xschem is started xschem will not read any

~/.xschem/xschemrc

file that contains the "per user" configuration.

# clear any existing definition if any
set XSCHEM_LIBRARY_PATH {}
# xschem base symbols (pins, ideal components, labels, ...) 
append XSCHEM_LIBRARY_PATH :${XSCHEM_SHAREDIR}/xschem_library
# add current directory
append XSCHEM_LIBRARY_PATH :[pwd]
# pdk models
append XSCHEM_LIBRARY_PATH :${PDK_ROOT}/gf180mcuD/libs.tech/xschem
