Hi Everyone, I'm trying to evaluate the test cases of ngspice over an installation. Using

make installcheck

steps over all the tests doing nothing. Does it require a parameter? Where are instructions to perform the different test cases (paranoia, check.sh, etc)? I'm going to dig deeper on the repository, hoping someone would give me some clarity about this. @Tim Edwards @Stefan Schippers

@aquiles viza You’re talking about the ngspice

Makefile

, right?

make installcheck

looks like it just reruns all the install targets.

make check

may be what you want. If you are checking a ngspice installation that has been compiled and installed locally, I doubt that you’ll need to rerun the

configure

scripts. If it’s in docker or some other pre-compiled environment, I don’t know.

Yep, I want to test a compiled ngspice inside a docker container, because verifying when building the contianer might add unnecessary overhead. Mmm, Now I realize the overhead can be avoided with staged-builds, but the system still should be verified on it's final stage, or outside the building process

@Mitch Bailey regarding june 3rd tapeout how are we supposed to do pre-check. As i currently have no idea how to do that.

Run LVS on the local precheck

make precheck
make run-precheck

but skip LVS on the platform precheck.

How can i download precheck

make precheck

clones the repo. You should probably specify the newest version

MPW_TAG=mpw-9i make precheck
make run-precheck

Actually i tried but i couldn’t get it error couldn’t find remote precheck

Is this in a caravel_user_project_analog clone?

no i don't have that where can i get that, secondly is it needed for chipalooza (june 3rd challenge)?

Ok, you’re referring to a design for the chipaloosa tapeout and not a chipignite tapeout. precheck is part of the chipignite tapeout flow. This makefile, https://github.com/efabless/caravel_user_project/blob/main/Makefile, has

lvs-<blockname>

targets for all

lvs/<blockname>/lvs_config.json

file. It also has the

make precheck

target to install the local precheck. If you wanted to create a

lvs_config.json

file for your design, you could run

make lvs-<blockname>

to run LVS locally at any level you wanted to. You’ll need to setup the

lvs_config.json

file with your schematic and layout. You can find examples here. I suggest starting from

lvs_config.user_analog_project_wrapper.json

.
