This project aims to add a streaming abstraction on top of CIRCT which in itself depends on MLIR.
Apart from cmake and Ninja, this project does not come with any prerequisites.
To reduce the amount of memory required, it is beneficial to install llvm's lld, as it is much more memory efficent than ld.
This project has a pinned version of CIRCT which in turn comes with a pinned verison of LLVM. These submodules can directly be initialized when the repository is cloned:
git clone --recurse-submodules [email protected]:Dinistro/circt-stream.gitBefore the circt-stream project can be built, its dependencies need to be built.
To make things easier, one should build CIRCT together with LLVM as follows:
mkdir circt/build && cd circt/build
cmake -G Ninja ../llvm/llvm \
-DCMAKE_BUILD_TYPE=Debug \
-DLLVM_ENABLE_PROJECTS=mlir \
-DLLVM_ENABLE_ASSERTIONS=ON \
-DLLVM_EXTERNAL_PROJECTS=circt \
-DLLVM_EXTERNAL_CIRCT_SOURCE_DIR=.. \
-DLLVM_USE_LINKER=lld \ # remove if lld isn't present
-DCMAKE_C_COMPILER=clang \
-DCMAKE_CXX_COMPILER=clang++ \
-DLLVM_CCACHE_BUILD=1 # remove if CCache isn't present
ninjaAfter CIRCT has been built, one can build this project as follows:
mkdir build && cd build
cmake -G Ninja .. \
-DLLVM_DIR=$PWD/../circt/build/lib/cmake/llvm \
-DMLIR_DIR=$PWD/../circt/build/lib/cmake/mlir \
-DCIRCT_DIR=$PWD/../circt/build/lib/cmake/circt \
-DLLVM_EXTERNAL_LIT=$PWD/../circt/build/bin/llvm-lit \
-DLLVM_ENABLE_ASSERTIONS=ON \
-DCMAKE_BUILD_TYPE=DEBUG \
-DLLVM_USE_LINKER=lld \ # remove if lld isn't present
-DCMAKE_C_COMPILER=clang \
-DCMAKE_CXX_COMPILER=clang++
ninjaThere are two types of tests. FileCheck tests can be executed with the following command:
ninja check-streamTo execute the integration tests, an installation of Icarus Verilog and pythons cocotb and cocotb-test packages are required.
