Porting to a New Technology
If you want to support a new technology, you will need to create:
- a setup script for each technology you want to use
- a technology directory for each technology with the base cells
We provide two technology examples for [SCMOS] and [FreePDK45]. Each
specific technology (e.g., [FreePDK45]) should be a subdirectory
(e.g., $OPENRAM_TECH/freepdk45) and include certain folders and files:
- gds_lib folder with all the .gds (premade) library cells:
- dff.gds
- sense_amp.gds
- write_driver.gds
- cell_1rw.gds
- replica_cell_1rw.gds
- dummy_cell_1rw.gds
- sp_lib folder with all the .sp (premade) library netlists for the above cells.
- layers.map
- A valid tech Python module (tech directory with __init__.py and tech.py) with:
- References in tech.py to spice models
- DRC/LVS rules needed for dynamic cells and routing
- Layer information
- Spice and supply information
- etc.
