You want to set

PDK_ROOT

and

PDK

.

export PDK_ROOT=$HOME/Desktop/ring_counter_caravel/dependencies/pdks
export PDK=sky130A

I done same

What do you get with this now?

echo $PDK_ROOT/$PDK
ls $PDK_ROOT/$PDK

it is done on above snap

seems problem with your PDK_ROOT export variable

what is next step to fix this issue?

if you're following caravel user guide. it look like: /home/vijayan/caravel_user_project/dependencies/pdks Then you've export

export PDK_ROOT=/home/vijayan/caravel_user_project/dependencies/pdks

initially i have installed in the in desktop open_pdks for rtl to gdsii openlane project

@sangamanath Instead of installing open_pdks separately, we’re suggesting that you install everything using

caravel_user_project

. I’d delete what you have now and follow the instructions here https://github.com/efabless/caravel_user_project/blob/main/docs/source/index.rst#section-quickstart

I made this setup after that can I harden my design any other steps needed

make setup

will install and pdk automatically

what is the next step ?

Yes.. harden your module with

make name

and update user_project_wrapper config.json and run

make user_project_wrapper

cd openlane cp -r user_proj_example/ring_counter cd .. cd verilog/rtl/ cp /home/sangamanath/Desktop/vlsi/OpenLane/designs/ring_counter/src/ringc.v ./

missing file path

caravel/verilog/rtl/caravel_power_routing.v

yes where i get this file?

"FP_PIN_ORDER_CFG": "dir::pin_order.cfg",

remove this line from

config.json

and try

Did you include the LEF for

user_proj_example

in the config.json file under

EXTRA_LEFS

?
