This contains a Rocket-attached suite of tests for verifying DANA's functionality based off of riscv-tests.
Tests are organized into the following categories:
- Smoke Tests -- Bare metal verification of all instructions. These are not intended to be comprehensive.
- Neural Network Tests -- Bare metal inference, learning, and simultaneously multi-processed (SMP) inference tests
Like with riscv-tests, the tests are intended to be built in varieties that use physical (-p) or virtual memory (-v). Currently, only the -p variants are built.
This requires that certain submodules in the Rocket Chip hierarchy are provided:
cd $ROCKETCHIP_DIR
git submodule update --init --recursive
Build neural networks for DANA:
cd $DANA_DIR
make
Build all tests:
cd $DANA_DIR/tests
autoconf
mkdir build
cd build
../configure
make
You can then run one of these tests if you have the emulator:
$ROCKET_CHIP/emulator/emulator-rocketchip-XFilesDanaCppPe1Epb4Config smoke/<test>-p
Due to the fact that these are bare-metal, the output is not terrifically interesting (it's either pass/fail). Running with Chisel printf commands enabled or to generate a waveform produces a more verbose output.
You can run these through spike, but these will naturally fail as spike does not have an attached accelerator.
