AOS-RISC-V

Initial Setup/Installation for FireSim

Please refer to the FireSim documentation.

Setting up the FireSim Repo

When you set up a manager instance during the initial setup process, check out a specific tag, 1.13.6.

git clone https://github.com/firesim/firesim.git
cd firesim
git checkout 1.36.6 # command to check out a specific tag
./build-setup.sh fast

Replacing the Existing "generator" Directory.

git clone https://github.com/yonghaekim/AOS-RISC-V.git
rm -rf ~/firesim/generator
cp -rf ./AOS-RISC-V/generator ~/firesim/

Building a New HW Design for AOS-RISC-V

1. In ~/firesim/deploy/config_build.ini,

• Under [afibuild], add a bucket name:

s3bucketname=firesim-aos

• Under [builds], add a build recipe name (comment out other things).

firesim-boom-singlecore-no-nic-l2-llc4mb-ddr3-aos

• Undr [agfistoshare], add a agfi name (comment out other things).

firesim-boom-singlecore-no-nic-l2-llc4mb-ddr3-aos

2. In ~/firesim/deploy/config_build_recipes.ini,

• Add a build recipe.

[firesim-boom-singlecore-no-nic-l2-llc4mb-ddr3-aos]
DESIGN=FireSim
TARGET_CONFIG=DDR3FRFCFSLLC4MB_FireSimLargeBoomConfig
PLATFORM_CONFIG=F75MHz_BaseF1Config
instancetype=f1.2xlarge
deploytriplet=None

3. Build a new HW design (This will take a long time, ~10 hours).

firesim buildafi

After completed, you will get a new agfi number for your new HW design.
Refer to the documentation for more details.

Running FireSim Simulations with AOS-RISC-V

1. In ~/firesim/deploy/config_runtime.ini,

• Change the default HW config.

defaulthwconfig=firesim-boom-singlecore-no-nic-l2-llc4mb-ddr3-aos

2. In ~/firesim/deploy/config_hwdb.ini,

• Add a new HW database.

[firesim-boom-singlecore-no-nic-l2-llc4mb-ddr3-aos]
agfi=agfi-062b20613c52a2313 # replace with your agfi after HW build completes
deploytripletoverride=None
customruntimeconfig=None

3. Launch FPGA instance(s) following the documentation.

4. Run binaries!
