Vyges PDK Descriptor Standard — schema overview

The Vyges PDK Descriptor Standard is published as a JSON Schema (2020-12) that presents any PDK uniformly to the tools that consume it. The schema has 21 top-level fields, of which 6 are required. It maps a PDK's heterogeneous on-disk layout onto a uniform set of collateral keys, so a flow resolves --pdk <name> + a corner (+ cell library) to concrete file paths regardless of node, foundry, or hosting. The canonical schema URL is https://vyges.com/schema/v1/vyges-pdk.schema.json.

What the schema describes

Top-level fields are grouped by what they capture about a PDK:

• Identity & process: name, version, node, foundry, process, design_types, description
• Source & access: source, access, license, maintainers, nda
• Layout & hosting: root, ciel, upstream
• Collateral resolution: default_corner, default_library, corners, cell_libraries, collateral

Use the schema

• • Browse PDK descriptors: vyges-tools/pdk-catalog — descriptors live in 6 public PDK mirrors
• • Validate a descriptor: any JSON Schema 2020-12 validator (e.g. ajv) against the canonical schema URL
• • Resolve collateral: pdk-store reads a descriptor and resolves --pdk <name> + a corner to concrete file paths for the Vyges Loom engines
• • Browse interactively: the live, hierarchical viewer below renders the schema in-page

The interactive viewer that follows loads the canonical schema dynamically and renders sections, fields, and types in a navigable tree. The static summary above is canonical and does not require JavaScript.
