用于芯片验证中的确定性事实查询和计算：daidir/FSDB debug、coverage、 SystemVerilog bit 计算、entry 解码、日志位置恢复、SVA 解释和波形渲染。 先按任务选择能力，再按环境选择 MCP 或 CLI。批量 pynpi 分析用 x-npi， 运维用 xverif-admin，持续知识用 xwiki。.
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
# xverif 这是唯一通用隐式入口。先判断用户要解决的问题，不要先猜 CLI/MCP。 > **Coverage exclusion 必须先持久化再关闭 session。** `exclude.add` 的 reason 只存在于 > 当前 xcov session；关闭 session 会永久丢失尚未导出的 reason。完成 coverage 分析后， > 必须先执行 `exclude.csv.export`，再执行 `export.exclude`，确认两类文件均成功后才能关闭。 > assert/function exclusion 先读取结构化 XOUT/JSON 的 `Axxxx`/`FCxxxx` gap；禁止使用已删除的 > exclusion selector 参数。关闭或丢失 session 后，尚未导出的 reason 无法恢复。 > Instance/covergroup/coverpoint/cross 容器使用专用 `exclude.instance.*` 与 > `exclude.functional.*` action；不支持 module selector。递归 instance 只依据 URG XML 真实层次， > remove 只依据 session 已记录的 exact ownership。 ## 任务路由 | 用户意图 | 能力参考 | | --- | --- | | 信号、scope、driver/load、波形、协议、active driver、窗口证明 | [xdebug](references/capabilities/xdebug.md) | | VDB coverage、hole、scope、源码 evidence | [xcov](references/xcov.md) | | literal、slice、mask、表达式 | [xbit](references/xbit.md) | | entry/descriptor/header fields | [xentry](references/xentry.md) | | 恢复 `L_XXXXXXXX` 源码位置 | [xloc](references/xloc.md) | | SVA temporal semantics | [xsva](references/xsva.md) | | `list.export` 后渲染 JPG/stats | [xwaveform workflow](references/workflows/waveform-render.md) | …

How to install
mdr add blank2077/xverif/xverif@sha256:77dbf8538443a322The line at the top of this page pins the label git:20260921.0262caf, 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.
