### [Go Back](./index.md#table-of-contents)

|
|
This page shows the basic setup for using OpenRAM.
|
|
|
|
# Basic Setup
|
|
|
|
## Dependencies
|
|
|
|
Please see the Dockerfile for the required versions of tools.
|
|
|
|
In general, the OpenRAM compiler has very few dependencies:
|
|
+ Docker
|
|
+ Make
|
|
+ Python 3.6 or higher
|
|
+ Various Python packages (pip install -r requirements.txt)
|
|
+ [Git]
|
|
|
|
## Docker
|
|
|
|
We have a [docker setup](./docker) to run OpenRAM. To use this, you should run:
|
|
```
|
|
cd OpenRAM/docker
|
|
make build
|
|
```
|
|
This must be run once and will take a while to build all the tools.
|
|
|
|
|
|
## Environment
|
|
|
|
You must set two environment variables:
|
|
+ OPENRAM\_HOME should point to the compiler source directory.
|
|
+ OPENERAM\_TECH should point to one or more root technology directories (colon separated).
|
|
|
|
You should also add OPENRAM\_HOME to your PYTHONPATH.
|
|
|
|
For example add this to your .bashrc:
|
|
|
|
```
|
|
export OPENRAM_HOME="$HOME/OpenRAM/compiler"
|
|
export OPENRAM_TECH="$HOME/OpenRAM/technology"
|
|
```
|
|
|
|
You should also add OPENRAM\_HOME to your PYTHONPATH:
|
|
```
|
|
export PYTHONPATH=$OPENRAM_HOME
|
|
```
|
|
|
|
Note that if you want symbols to resolve in your editor, you may also want to add the specific technology
|
|
directory that you use and any custom technology modules as well. For example:
|
|
```
|
|
export PYTHONPATH="$OPENRAM_HOME:$OPENRAM_TECH/sky130:$OPENRAM_TECH/sky130/custom"
|
|
```
|
|
|
|
We include the tech files necessary for [SCMOS] SCN4M_SUBM,
|
|
[FreePDK45]. The [SCMOS] spice models, however, are
|
|
generic and should be replaced with foundry models. You may get the
|
|
entire [FreePDK45 PDK here][FreePDK45].
|
|
|
|
|
|
### Sky130 Setup
|
|
|
|
To install [Sky130], you must have the open_pdks files installed in $PDK_ROOT.
|
|
To install this automatically, you can run:
|
|
|
|
```
|
|
cd $HOME/OpenRAM
|
|
make pdk
|
|
```
|
|
|
|
Then you must also install the [Sky130] SRAM build space and the appropriate cell views
|
|
by running:
|
|
|
|
```
|
|
cd $HOME/OpenRAM
|
|
make install
|
|
```
