Hi <@U01819B63HP> I wants to design BGR, but getting error with pnp transistors

Please send the BGR_dc.sch, i will test here.

hi <@U01819B63HP> , like this way you were expecting?

No, I need the schematic file you are opening with xschem, it is `BGR_dc.sch`, the circuit shown in the image.

I have no idea how to share it. but i am sharing

BGR_dc.sch

Yes you have attached the BGR_dc.sch, that was what i needed. Will try to look at it.

I have run the ngspice simulation on your circuit, it ran fine without errors

Just a comment, in your .control block you are writing the BGR_dc.raw file twice, this is not needed...
```.option reltol=1e-5
+  abstol=1e-14 savecurrents
.control
  save all
  op
  write BGR_dc.raw
  remzerovec
   write BGR_dc.raw
   set appendwrite
   print v(Vref)
.endc```

yes  <@U01819B63HP> you are correct, but could you check once my pnp is correct or not? i feel it's incorrect because in your pnp name `pnp_05v5_W3p40L3p40`     and in my pnp name is `pnp_05v5` . Tell me how to write like you.

<@U01819B63HP> could you show me you pnp edit properties.

<@U04R3BH2YBA> I have simulated your circuit with no changes, so if you don't get simulation running it means that the pdk installation is not correct or too old. I assume here you installed <http://opencircuitdesign.com/open_pdks/index.html|open_pdks>, which in turn downloads skywater-pdk, adding lot of corrections including BJT models.

thanks <@U01819B63HP> I will follow this and come back to you.

<@U01819B63HP> i did this but getting same

I don't know what to say. Your example works on my system. One thing you should try is to go into the open_pdks source directory you cloned from git, do another `make` followed by `sudo make install`. In some cases I had to run `make` twice to get all files in the pdk.

<@U01819B63HP> I uninstall open pdk and install again but getting same error..  could you please check any other possibilities.

No, do not uninstall, but after make run make a second time, then sudo make install

I am following docker. its working properly. thanks for your constant support
