# 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

## Docker
|

|

We have a [docker setup](./docker) to run OpenRAM.
|

## Dependencies
|

|

The OpenRAM compiler has very few dependencies:
|
||||
+ [Ngspice] 26 (or later) or HSpice I-2013.12-1 (or later) or CustomSim 2017 (or later) or [Xyce] 7.2 (or later)

+ Python 3.6 or higher
|
||||
+ Various Python packages (pip install -r requirements.txt)
|
||||
+ [Git]

If you want to perform DRC and LVS, you will need either:
|
||||
+ Calibre (for [FreePDK45])
|
||||
+ [Magic] 8.3.130 or newer
|
||||
+ [Netgen] 1.5.164 or newer
|
||||
+ [Magic] 8.3.197 or newer
|
||||
+ [Netgen] 1.5.195 or newer
|
||||
|

You must set two environment variables:
|

+ OPENRAM\_HOME should point to the compiler source directory.

[SCMOS] spice models, however, are generic and should be replaced with

foundry models. If you are using [FreePDK45], you should also have

# Docker images for OpenRAM #
|
||||
|
||||
## Installing Docker ##
|
||||
|
||||
There are a number of ways to install Docker. Pick your favorite.
|
||||
|
||||
* On Mac from docker.com with .app:
|
||||
https://docs.docker.com/docker-for-mac/install/
|
||||
|
||||
* On Windows from docker.com:
|
||||
https://docs.docker.com/docker-for-windows/install/
|
||||
|
||||
* On Ubuntu:
|
||||
https://docs.docker.com/install/linux/docker-ce/ubuntu/
|
||||
|
||||
NOTE: If you plan to use a VPN, do *NOT* use the Docker Toolbox for
|
||||
Mac or the docker from [Macports](https://www.macports.org/
|
||||
"Macports") as these require a network socket that breaks when you
|
||||
install some VPN software. To understand the difference, check out [this
|
||||
page](https://docs.docker.com/docker-for-mac/docker-toolbox/).
|
||||
|
||||
## Running Docker ##
|
||||
|
||||
### Terminal only ###
|
||||
|
||||
* To run as a generic user:
|
||||
```
|
||||
make mount
|
||||
```
|
||||
|
||||
## Updating the image ##
|
||||
|
||||
If there are updates to the image, you can pull a new one from the hub with:
|
||||
```
|
||||
make pull
|
||||
```
|
||||
This is not automatically done, so if you have a problem, make sure you are up-to-date.
|
||||
|
||||
## Building your own image ##
|
||||
|
||||
You can run the build script to build a local image:
|
||||
|
||||
```
|
||||
make build
|
||||
```
|
||||
|
||||
If you want to change things, modify the openram-ubuntu/Dockerfile and let me know what should be fixed.
