Stream Specialization CGRA Generator

As a submodule of dsa-framework, dsa-cgra-gen use JSON to describe CGRA, see example IR in IR directory.

Getting Started

Please add <ssfabric>.printIR(<your_cgra_name>) at the end of your CGRA description file.

run ss-cgra-gen from terminal

please run

sbt "runMain <your_cgra_package>.<ssfabric>"

For example:

sbt "runMain real.micro_demo"

run ss-cgra-gen from sbt

Please start sbt first

sbt

Then run ss-cgra-gen

runMain <your_cgra_package>.<ssfabric>

Generate RTL (Verilog via Chisel)

run ss-cgra-gen from terminal

please run

sbt "runMain cgra.driver.generator <your_cgra.json>"

For example:

sbt "runMain cgra.driver.generator <your_cgra.json>"

run ss-cgra-gen from sbt

Please start sbt first

sbt

Then run ss-cgra-gen

runMain cgra.driver.generator <your_cgra.json>
