ArtistIC is a framework can be used to
- Translate and insert ASIC art on top-metal layers.
- Render GDSII files at ultra-high fidelity.
ArtistIC is part of the PULP (Parallel Ultra-Low-Power) platform, where it is used render high-definition posters of our chips.
ArtistIC is in a experimental stage and might produce bad results. We are happy to receive your contributions through issues and PRs improving this framework. In a first step, the entire process has to be streamlined.
Logo Generation Only Tested for the IHP 130nm Open PDK
Prepare a temporary work directory:
mkdir -p meerkat_work
Export the top-metal layer:
python3 scripts/meerkat_interface.py \
-i ../examples/mlem/mlem_vanilla.gds.gz \
-m mlem_tm.gds.gz \
-g mlem_logo.gds \
-o mlem_chip.gds.gz \
-w meerkat_work \
-l 134
cd meerkat_work; klayout -zz -rm ../scripts/export_top_metal.py; cd ..
cd meerkat_work; gzip -d mlem_tm.gds.gz; cd ..
Transform the logo to a 1-bit b/w image:
convert examples/mlem/mlem_logo.png -remap pattern:gray50 meerkat_work/mlem_logo_mono.png
Transform the logo to GDS:
python3 scripts/meerkat.py \
-m "112,112,178,178" \
-i meerkat_work/mlem_logo_mono.png \
-g meerkat_work/mlem_tm.gds \
-l 134 \
-n mlem \
-s meerkat_work/mlem_logo.svg \
-o meerkat_work/mlem_logo.gds
Merge the logo into the chip:
cd meerkat_work; klayout -zz -rm ../scripts/merge_logo.py; cd ..
This generates the file meerkat_work/mlem_chip.gds.gz containing the generated top-metal logo.
For this example to work, ensure the previously generated GDSII is present in the work directory:
mkdir -p /dev/shm/renderics
cp meerkat_work/mlem_chip.gds.gz /dev/shm/renderics
Configuration is given through a json file. An example is provided in examples/mlem/mlem.json
The configuration can be checked using the Makefile. Make sure to point this to a large enough temporary work directory (abs path expected)!
make CFG_FILE=examples/mlem/mlem.json analyze
The black/white database can be rendered using:
make CFG_FILE=examples/mlem/mlem.json gen_raw
The resulting PNGs and PDFs can be created using:
make CFG_FILE=examples/mlem/mlem.json gen_pdfs
In this example, the generated PDF is called /dev/shm/renderics/PDF__mlem_0-0.pdf
The last step can be parallelized using the '-j' option.
Profit!
