Kelvin

Kelvin is a RISC-V32IM core with a custom instruction set.

Kelvin block diagram

More information on the design can be found in the overview.

Getting Started

  • If you are hardware engineer looking to integrate Kelvin into your design, check out our integration guide.
  • If you are a software engineer looking to write code for Kelvin, start with this tutorial.

Building

Kelvin uses bazel as it's build system. The Verilated simulator for Kelvin can be generated using:

bazel build //tests/verilator_sim:core_sim

The verilog source for the Kelvin core can be generated using:

bazel build //hdl/chisel/src/kelvin:core_cc_library_emit_verilog

Verilog source for the Matcha SoC can be generated using:

bazel clean --expunge  # To generate the ToT sha
bazel build //hdl/chisel:matcha_kelvin_verilog
