Simplify compiler bug workaround To prevent the compiler from combining the vset instructions, we could simply clobber the vtype. This workaround has been tested with gcc and clang. Change-Id: Id1b62efe5941f2508d6d99a2020329013f0dd0b4

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
