Refactoring core parts of toolchain_kelvin_v2 The following changes were made to upgrade dependencies and refactor the build process. * Upgrade RISC-V GNU Toolchian to git-branch `2025.08.29` * Upgrade LLVM project to version `20.1.0` * Simplify the build by removing the separate build step for `riscv-newlib` and update submodules. * Update toolchain url and sha256 in `WORKSPACE` file to support new toolchain * Update c++ toolchain configuration to include paths for GCC 15.1.0 Change-Id: I52b5cc37d47c2d672bd6c2b0f2b280883b37ac42
Kelvin is a RISC-V32IM core with a custom instruction set.
More information on the design can be found in the overview.
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
