Is there a way to get the code in open_pdks to only install Analog library and not to install the digital libraries? All analog related items in the PDK to make the installation faster?

Yes. You can do

cd sky130 ; make tools-a ; make primitive-a ; sudo make install

.

@Tim Edwards Do I need to do anything in the main folder first?

Yes, run

configure

first, then the above. The point is that there are specific targets in the sky130/Makefile that will just build specific parts of the PDK, like the primitive devices, the I/O, the digital standard cells, etc.

make tools-a

builds out the environment setup for magic that is used by the rest of the builds, so that's mandatory (but takes only a few seconds to run).

Thanks @Tim Edwards

Then

make io-a

.

inside sky130

Yes.

cd sky130 ; make tools-a ; make primitive-a ; make io-a ; sudo make install

.

Thanks @Tim Edwards Appreciate it.

In the log file, is there any indication of an error before this? There was at least one patch file that should have modified the same file that the above error claims is missing.

I'll dump the output to a file and send it on gist

All the patches are failing. Not sure why. I'm looking into it.

`./configure --prefix=

readlink -f ..

--enable-sky130-pdk`

Ah, if you do it that way, you would need to do

cd sky130 ; make prerequisites ; make tools-a ; make primitive-a ; ...

. But that will have the problem that

make prerequisites

will download the whole skywater-pdk repository, pull all of the libraries, and build them all. What you want to do is to clone the skywater-pdk separately and then just initialize the submodules you need, which is

sky130_fd_pr

for the primitives, and

sky130_fd_io

for the I/O libraries. There should be no need to do a

make timing

in the skywater-pdk repo because that only applies to digital standard cells. Then when you run

configure

for open_pdks, use

--enable-sky130-pdk=<path>

and give it the path to your skywater-pdk installation.

Let me try that.
