Hello, I have seen the video of prof. @Mitch Bailey and eventhough the clear explanation I would like to ask if there is any example on how to implement it. Until now we have work directly with the layout, so how can I do a LVS if I don't have the schematic? How can I do that? Should I do it with spice? Thank you

Hi @Eva, currently the easiest way is through the precheck system of Efabless’

caravel_project_wrapper

.

git clone <https://github.com/efabless/caravel_project_wrapper>
cd caravel_project_wrapper
make setup
make precheck

then create an

lvs

directory and add directories that match your cell names there. Under each cell name, create an

lvs_config.json

file. (See

$PRECHECK_ROOT/checks/be_checks/tech/$PDK

for examples.) Then just run

make lvs-<cellname>

glayout also has the ability to produce spice netlists. I don’t know the details though.

It does not exist caravel_project_wrapper

Sorry, the repo is

caravel_user_project

, the top level is

user_project_wrapper

.
