RapidChiplet

Setup Guide

Clone the RapidChiplet repository:

git clone https://github.com/spcl/rapid_chiplet.git

Install all requirements using pip:

cd rapid_chiplet
pip install -r requirements.txt

Build the BookSim2 [1,2] simulator:

cd booksim2/src
make

Reproducing results from the RapidChiplet paper [3]

python3 reproduce_results_from_paper.py

The resulting plots will be stored in the ./plots/ directory. Note that this script runs for multiple hours. The results might slightly differ from the paper due to different system specifications.

Usage

Inputs

Configure your chip design using the seven different input files. Check out the example files in ./inputs/ and the input description in the paper [3] to get started.

Visualization

Visualizations of chiplets and chip designs will be stored in the ./visualizations/ directory.

Visualize a chiplet:

python3 chiplet_visualizer.py -cf <chiplet-file> -cn <chiplet-name>

Example:

python3 chiplet_visualizer.py -cf inputs/chiplets/example_chiplets.json -cn compute_chiplet_4phys

Visualize a chip design:

python3 design_visualizer.py -df <design-file> 

Example:

python3 design_visualizer.py -df inputs/designs/example_design.json

Computation of Target Metrics

Each of the seven metrics can be toggled ON using a command line flag. For a summary of flags, run:

python3 rapid_chiplet.py -h

To compute all seven metrics, run:

python3 rapid_chiplet.py -df <design-file> -rf <results-file> -as -ps -ls -c -T -l -t

Example:

python3 rapid_chiplet.py -df inputs/designs/example_design.json -rf example_results -as -ps -ls -c -T -l -t

All results are stored in the ./results/ directory.

Cycle-Accurate Simulations using BookSim2 [1,2]

python3 run_booksim_simulation.py -df <design-file> -rf <results_file>

Example:

python3 run_booksim_simulation.py -df inputs/designs/example_design.json -rf example_simulation_results

All simulation results are stored in the ./results/ directory.
