An example of tool environment configuration for BWRC affiliates is given in `bwrc-env.yml`. Replace as necessary for your environment.

In this example, you will be running a SHA-3 accelerator with a dummy hard macro through the VLSI flow in the ASAP7 process. To elaborate the Sha3RocketConfig and set up all prerequisites for the build system:
## Building the design
In this example, you will be running a SHA-3 accelerator with a dummy hard macro through the VLSI flow in the ASAP7 process. To elaborate the Sha3RocketConfig (Rocketchip w/ the accelerator) and set up all prerequisites for the build system:
```shell
export MACROCOMPILER_MODE=' --mode synflops'
export CONFIG=Sha3RocketConfig
export TOP=Sha3AccelwBB
make buildfile
```
Note that because the ASAP7 process does not yet have a memory compiler, synflops are elaborated instead.
## Using HAMMER
HAMMER's configuration is driven by a JSON/YAML format. For HAMMER, JSON and YAML files are equivalent - you can use either one since HAMMER will convert them to the same representation for itself.
We start by pulling the HAMMER environment into the shell:

The configuration for the example design is contained in `example.yml` and the entry script with hooks is contained in `example-vlsi`. You may go through Hammer's readme to learn about the supported configuration options and how to write hooks.
In order to install the process, edit the keys `vlsi.technology.asap7.tarball_dir` if you already have the ASAP7 tarball downloaded and `vlsi.technology.asap7.install_dir` if you have already extracted it. If omitted, Hammer will automatically download and extract the tarballs into the `build/asap7-tech-cache` directory when you first run synthesis.
In order to install the process, download (and optionally extract) the ASAP7 PDK tarball. Then, edit the key `vlsi.technology.asap7.tarball_dir` if you want Hammer to extract for you or `vlsi.technology.asap7.install_dir` if you have already extracted it.
To synthesize a design:
To synthesize the just the SHA-3 accelerator with the hard macro we have to change the physical top module (this step is not necessary if you are pushing the entire Rocket-chip through the VLSI flow):
```shell
export TOP=Sha3AccelwBB
rm build/inputs.yml
```
Then, to run synthesis:
```shell
make syn
