Hi, Someone who can help me, I'm supposed to have the latest open pdk, but I still don't get the resistor values

@Juan Andres upstream xschem-sky130 has resistor symbols showing the resistance value as calculated from W and L geometry (this is an approximate value!). If you don't see the value you are probably using a container with an older version or xschem sky130 symbols.

i updated the pdk, but now the xschem got unconfigured, I cant see skywater

create a directory (example:

mkdir testdir

) and copy the pdk xschemrc file into it:

cp ...../share/pdk/sky130A/libs.tech/xschem/xschemrc testdir

, then cd into testdir and start xschem from there...

this file it empty, why?

For some reason, it’s not finding

ngspice_get_value.sym

, but does find the other primitive devices. Can you check the path? Select a device and press

q

. See if you can see a difference between the

ngspice_get_value

and other devices that are displayed correctly.

@Juan Andres send the schematic (.sch) file, send your xschemrc file. Try to add this line at the bottom of your xschemrc file:

append XSCHEM_LIBRARY_PATH :${XSCHEM_SHAREDIR}/xschem_library/devices

If nothing changes add this:

append XSCHEM_LIBRARY_PATH :${XSCHEM_SHAREDIR}/xschem_library:${XSCHEM_SHAREDIR}/xschem_library/devices

Thanks
