Hi everyone! I have a bit of a confusion. I have cloned the repository at https://github.com/efabless/caravel-gf180mcu for the upcoming shuttle. The PDK variant that the makefile uses is gf180mcuD, but I've been using the tag gf180mcuC. Can someone clarify which of these tags am I supposed to use?

The pdk version for gfmpw-1 is

gf180mcuD

. It has a thicker top metal layer. I think you use the

-force

option to load the

gf180mcuC

layout in magic and then rewrite everything with

gf180mcuD

.

Hi mitch i have layout design with gf180mcuc how can i translate to gf180mcuD

I’ve never done it myself, but I’ve seen Tim Edwards mention it on the #magic channel, I think. Can you try searching for

magic force

?

Thanks i will try.

Use

load <top_cell> -force

and then write everything out with

writeall force

.

Thanks but how can i install gf180mcuD because currently i have gf180mcuC installed on ubuntu using volare

I don't know; I don't use volare.

@Atif Khan Get the latest

Makefile

curl <https://raw.githubusercontent.com/efabless/caravel_user_project/gf180mcu/Makefile> > Makefile
export PDK=gf180mcuD
make setup

@Mitch Bailey hi i get only libs.tech not other files

It should be set in the Makefile, but you can override it with local settings. Try

env | grep PDK

If

PDK

is set, you can

unset PDK

and then

make setup
