i am getting this error in xscheme_sky130 directory when i was running xschem,can anyone resolve this error
yeah it is resolved now i set USR_conf_dir to proper location
but why is it not there by default
s
Can you post the output of 'xschem --version' and your xschemrc file in .xschem/xschem_sky130/ ?
v
it is showing v2 8.1
s
it's too old, this is the ubuntu pre-packaged version, please uninstall the xschem package and install xschem from source files, get it here: • Follow build instructions here: , the steps are also explained in this video

or on youtube ▾

if you have problems whatching the first video.
v
ok sir thanks
s
you are welcome!. If you have issues let me know
unfortunately linux distributions (ubuntu, debian, fedora) take months to get a software packaged so having updated version is a problem in a rapidly evolving environment like skywater...
v
sir here after did sudo make install,i am not able to open xschem
s
try /usr/local/bin/xschem
v
yeah when i restarted system it is opening
but now i am not getiing window to edit netlist after clicking simulation,i did as you told in video
s
if you select 'Edit netlist' and nothing happens it means that the editor xschem want to use is not installed on the system. default is gvim. Open your ~/.xschem/xschemrc and find /uncomment this line: set editor .... you need to set an editor that is available on the system. Default if not defined is: set editor {gvim -f} if you have xedit do this: set editor {xedit}
v
also i am not able to see simulation wihin xschem
i installed gvim ,now i could edit netlist,but i am not able to see simulation
s
@Varun Majji can you please give some more details? you press the 'Simulation' button and nothing happens? do you have ngspice installed? if you do 'ngspice -h' in a terminal do you get some answer from ngspice? try also 'ngspice -v' and tell me the ngspice version you have on the system 🙂
v
ok sir i will do it and update u
sir it is showing ngspice-34 ,is that what u mean by version
but even now that simulation button is not working
my bad ,i forgot to download xterm,thats why simulation terminal was not opening,luckily thanks u placed a error log option where i found it sir that i xterm is not downloaded
