CGRA Test

This repo tests every operators that Halide-CGRA uses and will be mapped to CGRA. This is an end-to-end test, aiming to discover any bugs in the downstream tools, such as CGRAMapper, PnR, Bitstream Builder, and PE implementations.

Install

THe entire suite depends on several repos in Stanford AHA projects. As a result, there will be some particular requirements on some of the components, namely:

1. csh will be used internally, as used in CGRAGenerator
2. Python3 has to be used, as used in TestBenchGenerator
3. verilator will be used to verify the end result

$ sudo apt-get install csh
$ sudo apt-get install verilator

Run the tests

First we need to set the environment for testing.

$ source ./scripts/set_env.sh

We also need to generate cgra_info.txt file and download PnR tools.

(cgra) $ ./scripts/cgra_gen.sh
(cgra) $ ./scripts/pnr_setup.sh

Then we run the tests

(cgra) $ ./scripts/run_tests.sh

Finally, clean up the test environment.

(cgra) $ deactivate_cgra

• abs
• ucomp
• arith
• uminmax
• bool
