Welcome to RISCV-BOOM's documentation!

The Berkeley Out-of-Order Machine (BOOM) is a synthesizable and parameterizable open-source RISC-V out-of-order core written in the Chisel hardware construction language. The goal of this document is to describe the design and implementation of the core as well as provide other helpful information to use the core.

Useful Links

The BOOM source code can be found here: https://github.com/riscv-boom/riscv-boom.

The main supported mechanism to use the core is to use the Chipyard framework: https://github.com/ucb-bar/chipyard.

The BOOM website can be found here: https://boom-core.org.

The BOOM mailing list can be found here: https://groups.google.com/forum/#!forum/riscv-boom.

Quick-start

The best way to get started with the BOOM core is to use the Chipyard project template. There you will find the main steps to setup your environment, build, and run the BOOM core on a C++ emulator. Chipyard also provides supported flows for pushing a BOOM-based SoC through both the FireSim FPGA simulation flow and the HAMMER ASIC flow. Here is a selected set of steps from Chipyard's documentation:

Note

:numref:`quick-start-code` assumes you don't have riscv-tools toolchain installed. It will pull and build the toolchain for you.
