Hello everyone, I going through this flow for an counter example: https://caravel-user-project.readthedocs.io/en/latest/ And now at the run full chip simulation step I am getting this error, Can anyone give me some hint on how can resolve?

@User For one, your

PDK_ROOT

doesn't appear to be set. Also running as

sudo

may be causing problems with the userid setting. Can you try this?

export PDK_ROOT=$OPENLANE_ROOT/pdks
make verify-io_ports

Ya sure. Will try this out.

Apart from PDK_ROOT, look like there docker image installation issue .. Do you see efabless/dv_setup:latest in your docker image list ?

Yes PDK_ROOT is correct. there is some issue with volume permissions. Yes I see efabless/dv_setup:latest

@User You might try this If you have

CARAVEL_ROOT

set,

unset CARAVEL_ROOT

If you're executing in

caravel_user_project

, the

Makefile

will automatically set

CARAVEL_ROOT=$PWD/caravel

which is the default destination when you execute

make install

. The screen copy you sent seems to indicate that you've set

CARAVEL_ROOT=/caravel

. Is that what you intended?

Yes so I am inside caravel_user_project and running the RTL simulation. that is why I used this to go to caravel location that is pwd/caravel.

I may be misunderstanding you, but

/caravel

is not the same as

$PWD/caravel

. What do you get when you execute the following in

/home/lifam/Documents/shivani/caravel_user_project

?

echo $CARAVEL_ROOT
ls $CARAVEL_ROOT
ls caravel

Looks good! (But I see you set

CARAVEL_ROOT

before executing) Try this

unset CARAVEL_ROOT
make verify-io_ports

and let me know what you get.

So, I am following this

export PDK_ROOT=<pdk-installation-path>
export CARAVEL_ROOT=$(pwd)/caravel
# specify simulation mode: RTL/GL
export SIM=RTL
# Run RTL simulation on IO ports testbench, make verify-io_ports
make verify-<testbench-name>

So, now without setting the 3 variables directly should I run make command?

You need to set

PDK_ROOT

and

SIM

but you need to replace

<pdk-installation-path>

with the path to your pdk installation. If you have

OPENLANE_ROOT

set correctly and the pdks are installed in the default location, you should be able to

export PDK_ROOT=$OPENLANE_ROOT/pdks

You can set

CARAVEL_ROOT

if you want, but the default will be set correctly in your case.

I don't see the

OPENLANE_ROOT

shoud be set in my case bcoz after running RTL simulation openlane comes in that document.

@User Ok, your setup is a bit different than what I've been using. Sorry for any misleading advice. The document you're referencing says you can either build native

make pdk

or non-native

make pdk-nonnative

, but I couldn't find the target for

pdk

in the

Makefile

. So you might try something like this

export PDK_ROOT=/home/lifam/Documents/shivani/pdks
make pdk-nonnative
make verify-io_ports

The docker image you're using has openlane pre-installed, it seems.

yes it worked, thank you for your help.
