A machine-readable Sail golden model for RISC‑V Vector (RVV) is implemented with configurable vector register widths, read/write helpers, CSR functions and instruction encodings; backbone and instruction phases are complete and verification is ongoing using Spike as the reference. A Python Talon random generator emits assembly via YAML constraints, integrates with RISCOF, and produces test suites; prototype release targets end of September, full RVV test suite by end of October and Talon RVV support within the year, with remaining work on coverage and ambiguous spec behaviors.
