Chimera-SDK is a bare-metal development platform for ASICs based on the Chimera architecture, a microcontroller SoC for multi-cluster, heterogeneous systems.
Chimera and Chimera-SDK are developed as part of the PULP project, a joint effort between ETH Zurich and the University of Bologna.

If you are working on an IIS system, you can use the preinstalled SEPP packages to add the correct versions of the RISC-V toolchain and questasim into your path. If you use bash, you might run
riscv bash
If you are not on an IIS system, please ensure a RISC-V toolchain and questa installation are available in your path by checking that the output of
which riscv32-unknown-elf-gcc
is not empty.
To build the SDK and all tests contained in the SDK, run
mkdir build && cd build
cmake -DTARGET_PLATFORM=[YOURTARGETPLATFORM] ../
cmake --build .
The resulting binaries will be stored in build/bin, and can be used within the chimera repo as tests.
To format all source files, run
python scripts/run_clang_format.py -ir sw/
Our CI uses llvm-12 for clang-format, so on IIS machines you may run
python scripts/run_clang_format.py -ir hal/ --clang-format-executable=/usr/pack/riscv-1.0-kgf/pulp-llvm-0.12.0/bin/clang-format
python scripts/run_clang_format.py -ir targets/ --clang-format-executable=/usr/pack/riscv-1.0-kgf/pulp-llvm-0.12.0/bin/clang-format
python scripts/run_clang_format.py -ir tests/ --clang-format-executable=/usr/pack/riscv-1.0-kgf/pulp-llvm-0.12.0/bin/clang-format
