Reticle Stitcher

Tool for stitching a full MPW reticle using gf180mcu for delivery to a foundry.

Usage

Enable the Nix shell:

nix-shell

To run the stitcher, supply the manifest and tile map:

python3 reticle_stitcher.py G801/manifest.csv G801/tilemap.csv reticle.oas reticle_filled.oas

File Structure

The following file structure should be created for each shuttle:

G801
|-- tilemap.csv
|-- manifest.csv
|-- MOLE
|   |-- chip_top.oas
|-- KIAN
|   |-- layout.oas
|-- CAFE
|   |-- chip.oas
...

Manifest

The manifest contains a list of all projects.

The following entries are required in the CSV file:

• CODE: the project code (e.g. MOLE, KIAN, CAFE)
• PROJECT: the project name
• SLOT: one of 1x1, 1x0p5, 0p5x1, 0p5x0p5
• TOP: top-cell name
• HASH_MD5: hash in given format of the output file
• LAYOUT: relative path to the chip layout (e.g. MOLE/chip_top.oas)

These are the required entries. However, additional entries can be added for documentation purposes.

Tile Map

The tile map is the mapping from project to tile location.

• A 1x1 slot is 2x2 tiles.
• A 0.5x1 slot is 1x2 tiles.
• A 1x0.5 slot is 2x1 tiles.
• A 0.5x0.5 slot is 1x1 tiles.
