xiangshan-mpt-dut SKILL.md skillA
xiangshan-mpt-dut from openxiangshan/xiangshanlab is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Generate or update a compact Chisel/Scala DUT that isolates XiangShan MPT checking logic from the full core. Use when working on XiangShan MPT, MptChecker.scala, L2TLB MPT wiring, backend/decode mfence support, or the custom smmpt/mmpt CSR path, especially when asked to regenerate a simple DUT around MPT upstream/downstream logic for simulation or verification.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# XiangShan MPT DUT ## Workflow Use this skill to rebuild a small DUT around XiangShan's MPT checker without dragging in the whole core. 1. Inspect the local XiangShan source before editing. Prefer `rg` and targeted `sed` reads. 2. Load [references/mpt-dut-generation.md](references/mpt-dut-generation.md) before implementing the DUT. 3. Keep the DUT focused on `MptChecker` and its real upstream/downstream contract: - upstream request/response: `MptReqBundle` and `MptRespBundle` - CSR input: `TlbCsrBundle.mmpt` - flush input: `SfenceBundle`, including `mfence` when `HasMptCheck` - memory side: `L2TlbMemReqBundle` request plus XLEN response - PMP side: `PMPReqBundle` and `PMPRespBundle` 4. Preserve the XiangShan parameter gate: the DUT should be meaningful only with `HasMptCheck = true`. 5. Do not model the full backend, ROB, LSQ, PTW cluster, or complete L2TLB unless the user explicitly asks. Replace them with small drivers, arbiters, memories, or stubs that preserve handshake semantics. ## Output Shape Prefer one of these forms, matching the repository style: …

How to install
mdr add openxiangshan/xiangshanlab/xiangshan-mpt-dut@sha256:5aadaf6dc64ac302The line at the top of this page pins the label git:20260724.bb8f3f1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
