I tried running inverter as my verilog file but getting this error.. also attached the pdn.log file.. can anyone say me how to change the spacing of metal layer 4??

Hello, After successfully running the

mul32

following the tutorial I was trying to run the flow for a basic verilog adder, getting the following issue: Can anyone please help? I tried changing the

PL_TARGET_DENSITY to 0.59 and 0.60

a different issue arises then. I also tried changing the CORE_HEIGHT Sorry, can't figure out what I'm missing...

I'm trying to run

openlane

on the example user_proj_mul32 from the tutorial. 1. I've cloned the

caravel_user_repo

and exported the

OPENLANE_ROOT

and

PDK_ROOT

environment variables. 2. I've copied the config files into the openlane folder. The config files are now in

json

format instead of

tcl.

Could someone please assist with following errors: 1. pdk folder is empty (image attached). When is it expected to be populated and how to do so ? ( I had no issues in hardening only the macro spm32 as the pdks were built into OpenLane/pdk but I didn't see any corresponding step for the integration into caravel: IMAGE ATTACHED) 2. The config file I see is a

json file

with the same variables as the

tcl file.

So I've edited the json file but I get an error wile running openlane using make

user_proj_mul32

. How do I get-around it?

Could someone please help ?

This was one of the earlier errors I saw when building using make setup,

volare: command not found

. Is it the reason the

pdk

directory is empty ?

@Marwan Abbas I'm seeing a

Monitor: Timeout, Test Mega-Project WB Port (RTL) Failed

message in the DV step running

make verify-wb_spm-rtl

. Could you kindly advise how to address it?
