A variant description file is a TOML file describing the details of an LWC protected hardware implementation. As suggested in the "Call for Protected Hardware Implementation", a variant description file serves as an organized container of information and meta-data required for automated evaluation of an LWC hardware implementation.
The structure of a LWC variant description file is described as a JSON Schema in the file lwc.schema.json.
The schema provides a precise specification of the hierarchy as well as type, format, and description of the data fields.
Example variant description files are provided in the examples subfolder.
examples/TinyJAMBU_DOM/tinyjambu-dom1-v1.toml
