Question

Hi I am trying to use sky130 pdk with openlane tools I followed the steps in github but i had a problem to install the docker version needed as I am using VM centos6 So I Continued with the docker version I have 1 5 I ran flow tcl design spm as a test An error appeared regarding package require json in all tcl script So how I could install or get this package to avoid this error

Hi < sarah> can you list the commands you used here and did you mount the docker eventually with 1 5 version or did the docker build mounting fail eventually Because the error you re getting means you ran ` flow tcl` outside of the `openlane rc3` docker container Also since you re using a centos6 VM it would be very easy for you to run OpenLANE natively by untaring the files inside `docker build tar ` and pointing to the binaries build locations in your ` bash profile` Although this is kind of hectic

The commands I used git clone git github com efabless openlane branch rc3 cd openlane docker build make merge cd docker run it v $ pwd openLANE flow v $PDK ROOT $PDK ROOT e PDK ROOT=$PDK ROOT u $ id u $USER $ id g $USER openlane rc3 then flow tcl design spm in openlane directory

And this runs without showing any error messages up to flow design spm which breaks i e did the docker build and mounting succeed the bash changed Also bear in mind that you ll have to update the pdk to the commit hashes mentioned in rc3 to get the best of the flow But this is unrelated to this issue for now

No errors but the return values of make merge

So it returns with the 1 5 docker version is that ok

sarah · Answer

Regarding the bash profile I didn t change it but linked all inside the docker build build inside usr bin

Amr Gouhar · Answer

I m afraid this means the docker version you have won t build the docker file we made

Amr Gouhar · Answer

As for running natively you ll have to figure it out I only did it once for two of the tools only under the guidance of < Ahmed Ghazy> months ago But the general guideline is untar the files into some directory and point to them using the same names environment variables defined in this in your bash profile file And of course install all dependencies mentioned in that same docker file Then theoretically you ll be able to run openlane natively

Thanks Amr json package is now found after install dependencies in dockerfile
