What it does
Vivado Constraints Authoring is an agent skill from mapleleavessssssss-wq/vivado-mcp. 为 Vivado 工程建立或审查 XDC 时钟、I/O 延迟和时序例外，依据板级与接口参数验证对象和约束覆盖；不猜引脚、频率或外设时序，不用例外掩盖违例。
Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. It works with Model Context Protocol. The repository describes itself as: Vivado MCP server — 让 Claude Code / Cursor / Codex 驱动本地 FPGA 全流程。30 个精选工具、8 个证据驱动 Prompt、doctor 环境自检、GUI/Tcl/attach 会话，以及时序和 CRITICAL WARNING 中文诊断。 The licence is Apache-2.0.
When your agent uses it
- Agent Workflows work in your project
Example prompts
- “/vivado-constraints-authoring”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- primary clock 绑定真实输入对象，周期与波形来自已确认规格。generated clock 绑定实际 source/target，记录分频、倍频、相位；核对 IP 自动生成时钟，避免重复约束或把相关时钟定义成独立 primary clock。
- 分别推导 I/O 的 -min 和 -max，明确参考边沿、外设参数及板级差分延迟的符号。输出 hold 可能对应负 output delay，不能取绝对值“修正”。DDR/双边沿接口分别覆盖边沿并核对 -add_delay，不套单边沿模板。
- 写入前用 get_ports / get_pins / get_clocks 核对目标对象与数量；处理空集合、通配符误匹配和重复时钟。参数经 safe_tcl 传递；“命令没报错”不代表对象都正确。
- 例外逐条绑定功能证据。异步 clock group 与 false path 会覆盖重叠路径的 max delay；multicycle 同时影响 setup/hold，须按真实协议预算核对二者，不能只放宽 setup。总线 skew 独立验证。
- 修订写入工程实际 XDC，确认属于已启用的目标 fileset；只设置会话属性不构成可重建交付。运行受影响阶段后重读报告。
What it can do on your machine
Read from SKILL.md and the folder at commit 41745b2. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are python).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Vivado Constraints Authoring loads about 518 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 97 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- 为 Vivado 工程建立或审查 XDC 时钟、I/O 延迟和时序例外，依据板级与接口参数验证对象和约束覆盖；不猜引脚、频率或外设时序，不用例外掩盖违例。
Vivado XDC 编写与覆盖核对
可用入口：get_project_info、xdc_lint、get_timing_report、get_cdc_report、run_tcl、safe_tcl。
用户要求编写或修复时，在已有授权范围内编辑工程约束；只要求检查时交付审查结果。保留原有接口、器件和时序意图。没有板级资料时可以分析时钟与对象，不能猜 PACKAGE_PIN、IOSTANDARD 或外设延迟。
补齐建立约束的信息
核对工程 top、器件、已启用 XDC/fileset、处理顺序、IP 自带约束，以及接口参考时钟和同步关系。输入包括：primary clock 周期/波形、generated clock 源与变换、外设 clock-to-out/setup/hold、板级数据/时钟延迟差、引脚与电气标准。
缺参数时列出受影响路径与最小缺失输入，继续检查其他部分。不能把未知 -min/-max 写成 0，也不能把内部时钟频率当成外部接口的完整预算。
get_project_info(session_id="design")
xdc_lint(session_id="design")
run_tcl(command="report_clocks -return_string", session_id="design")xdc_lint 是静态预检；报告没有打开设计是阶段限制。对象、时钟关系与时序覆盖须在合适的已展开/综合设计上核对，不能只凭静态 lint 通过作结论。
编写与验证
- primary clock 绑定真实输入对象，周期与波形来自已确认规格。generated clock 绑定实际 source/target，记录分频、倍频、相位；核对 IP 自动生成时钟，避免重复约束或把相关时钟定义成独立 primary clock。
- 分别推导 I/O 的
-min和-max，明确参考边沿、外设参数及板级差分延迟的符号。输出 hold 可能对应负 output delay，不能取绝对值“修正”。DDR/双边沿接口分别覆盖边沿并核对-add_delay，不套单边沿模板。 - 写入前用
get_ports/get_pins/get_clocks核对目标对象与数量；处理空集合、通配符误匹配和重复时钟。参数经safe_tcl传递；“命令没报错”不代表对象都正确。 - 例外逐条绑定功能证据。异步 clock group 与 false path 会覆盖重叠路径的 max delay；multicycle 同时影响 setup/hold，须按真实协议预算核对二者，不能只放宽 setup。总线 skew 独立验证。
- 修订写入工程实际 XDC，确认属于已启用的目标 fileset；只设置会话属性不构成可重建交付。运行受影响阶段后重读报告。
固定只读命令示例；版本选项以当前 Vivado help 与实际返回为准：
run_tcl(command="check_timing -verbose", session_id="design")
run_tcl(command="report_clock_interaction -return_string", session_id="design")
run_tcl(command="report_exceptions -return_string", session_id="design")
get_timing_report(session_id="design", output_format="json")覆盖与完成条件
检查 no-clock、multiple-clock、未约束内部端点、缺 I/O delay、无效或被覆盖的 exceptions；跨域传输用 get_cdc_report 核对结构和协议。bus skew 单独取得 report_bus_skew。版本不支持检查时保留原错误并标记未验证，不把失败查询当零问题。
交付约束的参数依据、精确对象、文件与同条件复测。区分“XDC 已写入”“覆盖已核对”和“实现满足时序”：完整签核还需当前 post-route setup/hold/pulse-width、DRC/methodology 及适用 CDC。不得降低频率、删约束或隐藏真实违例制造通过；两轮无改善时重查假设。
