Generate a complete UVM testbench scaffold for a single IP from its spec documents (docx/pdf/md) and register table (xlsx/csv/md/IP-XACT). Use whenever the user asks to "generate a UVM tb", "build a verification environment", "scaffold a testbench", "create a UVC", "set up DV for this IP", or anything equivalent in Chinese ("帮我生成验证环境", "搭一个 tb", "做 UVM 环境", "做这个 IP 的验证"). Also trigger when the user points at a directory containing an IP spec and asks Claude to "verify it" / "test it" without naming UVM explicitly. Produces a runnable UVM tb (APB / AHB-Lite / AXI4-Lite as first-class buses; other single-channel buses via a generic fallback) with sanity + register-access tests passing, plus a DE-friendly `tb_api::` task BFM.
