@radhe-2022 Follow below steps:

export PDK_ROOT=<absolute path to GF180 PDK >`
export PDK=gf180mcuC
make mount

[proppy]

Alternatively:

export PDK_FAMILY=gf180mcu # set environment variable for volare
export PDK=gf180mcuC # set environment variable for the rest of the toolchain
make
make test

should allow volare to resolve and download the new GF180MCU PDK.

See also https://caravel-user-project.readthedocs.io/en/latest/ for instructions on how to set up the caravel_user_project environment to submit a project to the recently announced GF-MPW0 Open MPW shuttle: https://opensource.googleblog.com/2022/10/announcing-globalfoundries-open-mpw-shuttle-program.html

I'm a beginner I followed.. launched terminal in home directory

git clone https://github.com/The-OpenROAD-Project/OpenLane.git cd OpenLane EXPORT PDK_FAMILY=gf180mcu EXPORT PDK=gf180mcuC sudo make sudo make test

@radhe-2022 Where GF180 pdk installed in your machine? Current OpenLane master will not install gf180 pdk by default. Only through caravel flow it works: https://github.com/efabless/caravel_user_project

launched terminal in home directory

Can you paste the full command outout?

EXPORT PDK_FAMILY=gf180mcu EXPORT PDK=gf180mcuC

export should be in lowercase.

sudo make sudo make test

sudo shouldn't be strictly required.

Done..! Thankyou so much sir @proppy @vijayank88

Heading towards my first design to get tapeout
