Synthesis
CoreBlocks synthesizes Core circuit to test how many resources it consumes as the project
grows and more functionalities are added.
In order to perform synthesis you will need to install following tools:
These tools may need manual compilation from git repository, that can take some time.
You can use docker images that have installed all required tools to perform synthesis:
To build the AmaranthSynthECP5.Dockerfile yourself use following command:
docker build --platform linux/amd64 -t "amaranth-synth:ecp5" -f ./docker/AmaranthSynthECP5.Dockerfile .
Script named synthesize is used to perform the Core synthesis.
Example usage:
./scripts/synthesize --help
./scripts/synthesize --platform ecp5 --verbose
To collect synthesis information we use script named parse_benchmark_info.
This script parses the output of the synthesis tool and extracts the following information:
- Max clock frequency
- Number of logic cells used
- Number of carry cells used
- Number of RAM cells used
- Number of DFF cells used
For each commit on master branch, CI runs the synthesis and saves the parameters collected by parse_benchmark_info script.
Graphs generated from this information are available on a dedicated subpage.
