Hi, all How can i get the GDSII file of caravel, i mean my user_project_wrapper + management_wrapper?, i try with make ship but it didn't work.

@Emilio Baungarten sky130? gf180? The caravel lite repo is installed by default for sky130. 1.

export CARAVEL_LITE=0

2.

make install

Should update the delete and reinstall the full caravel repo at

CARAVEL_ROOT

. The 2 steps before

make ship

are 1.

env USER_ID=00000000 make set_user_id

where

00000000

is an 8 digit hexadecimal number. This will program the internal id and also set the metal lettering on the final chip. If you want to test reading the id, I suggest a number other than

00000000

. 2.

make gpio_defaults

this will use the information in

verilog/rtl/user_defines.v

to set the power up configuration for each gpio. If these complete, then you can run

make ship

. (This is for the digital version. Use

make truck

for the analog version). You may want to run

make compress

after that because the previous steps uncompressed several large files.

Hi David, Thanks for your answer, I followed your instructions and I got the following message when I used make ship

Is

Caravel_HLS

a clone of

caravel_user_project

? What are

PDK_ROOT

and

PDK

set to? Can you post the full output and not just the last screen?

Yes Caravel_HLS is a clone of caravel_user_project with the full version installed. PDK_ROOT and PDK are set to: declare -x PDK="sky130A" declare -x PDK_ROOT="/media/baungarten/CentOS7/LASCAS_2024/Caravel_HLS/caravel/dependencies/pdks" I Attach the output after the make ship command.

make install

deletes the caravel directory, so your pdk got deleted also. I recommend setting

export PDK_ROOT=/media/baungarten/CentOS7/LASCAS_2024/Caravel_HLS/dependencies/pdks

and then

make pdk-with-volare

I get the following error:

Failure to read entire subtree of the cell.

I/O error in writing file /media/baungarten/CentOS7/LASCAS_2024/CAravel_HLS/gds/caravel.gds.

File may be incompletely written.

make[2]: Leaving directory '/media/baungarten/CentOS7/LASCAS_2024/CAravel_HLS'

Make ship completed.

The terminal shows:

@Emilio Baungarten Let’s rearrange the order. You should probably set

PDK_ROOT

before anything. This may get deleted, give it it’s own directory.

$ git clone <https://github.com/efabless/caravel_user_project.git> Caravel_HLS
$ export PDK_ROOT=$PWD/Caravel_HLS/dependencies/pdks  
$ export PDK=sky130A
$ export CARAVEL_LITE=0
$ cd Caravel_HLS/
$ make setup
$ env USER_ID=0000000F make set_user_id 
$ make gpio_defaults  
$ ulimit -n 2024
$ make ship

Note that is will create a caravel chip based on default data. Is your design data available anywhere?

Hi David, Sorry for this series of troubles. I followed your instructions this is my history: 1997 git clone https://github.com/efabless/caravel_user_project.git Caravel_HLS 1998 export PDK_ROOT=$PWD/Caravel_HLS/dependencies/pdks 1999 export PDK=sky130A 2000 export CARAVEL_LITE=0 2001 cd Caravel_HLS/ 2002 make setup 2003 env USER_ID=0000000F make set_user_id 2004 make gpio_defaults 2005 ulimit -n 2024 2006 make ship 2007 history But at the end of the flow i get a similar result:

Ahh. That may be the development version. Sorry. How about this

git clone -b mpw-9e <https://github.com/efabless/caravel_user_project.git> Caravel_HLS

The same problem 😅

Looks like the

Terminal_output

is missing the beginning of the output. Is there a

signoff/build/make_ship.out

file? Can you share it?

Here is the file.

Looks like you’ll should update to

magic

Error:  Magic version 8.3.411 is required by this techfile, but this version of magic is 8.3.348.

Can you list the contents of

Caravel_HLS/mag

? Maybe the standard cells have been mistakenly duplicated there. Is

CARAVEL_ROOT

set to anything? (

echo $CARAVEL_ROOT

)

list of Caravel_HLS/mag: caravan_core.mag user_id_programming.mag caravel_core.mag user_id_prog_zero.mag gpio_defaults_block_0403.mag user_id_textblock.mag gpio_defaults_block_0801.mag user_project_wrapper.mag gpio_defaults_block_1803.mag user_proj_example.mag mag2gds_caravel.tcl echo $CARAVEL_ROOT shows nothing. and how can i update magic?, i use "sudo apt-get install magic" but says that i get the newest version of magic "magic is already the newest version (8.2.157+ds.1-1)"

how about the contents of

caravel/mag

? let’s worry about updating magic later.

advSeal_6um_gen.mag caravel.mag empty_macro.mag open_source.mag buff_flash_clkrst.mag caravel_motto.mag gpio_defaults_block.mag primitives caravan_core.mag caravel_openframe.mag gpio_logic_high.mag seal_ring_corner_abstract.mag caravan-eco-antenna.mag chip_io_alt.mag hexdigits simple_por.mag caravan_logo.mag chip_io_gpio_connects_horiz.mag housekeeping_alt.mag spare_logic_block.mag caravan.mag chip_io_gpio_connects.mag housekeeping.mag user_analog_project_wrapper.mag caravan_motto.mag chip_io.mag .magicrc user_id_programming.mag caravan_power_routing.mag chip_io_openframe.mag manual_power_connections.mag user_id_textblock.mag caravan_power_routing_orig.mag constant_block.mag mgmt_protect_hv.mag user_project_wrapper.mag caravan_signal_routing.mag copyright_block_a.mag mprj2_logic_high.mag xres_buf.mag caravel_clocking.mag copyright_block.mag mprj_io_buffer.mag caravel_core.mag copyright_block_of.mag mprj_logic_high.mag caravel_logo.mag empty_macro_1.mag openframe_project_wrapper.mag

looks good. Actually, this may be a magic version problem. In some other directory

which magic

to find where magic is installed. Do you have write permission on this directory? If the file is

/usr/local/bin/magic

and you have write permission, then the install directory below will be

/usr/local

. If you don’t have write permission the user

$HOME/local

as the install directory.

git clone 
cd magic
./configure --prefix=<install_directory>
make
make install

If you used

$HOME/local

as your install directory, you’ll need to modify your

PATH

.

export PATH=$HOME/local/bin:$PATH

I followed your instructions and yes the problem was magic version, the

make ship

works, and now i will try with my design. Thanks for your support and my apology for this large post.
