Vivado

CI

Vivado CLI is a CLI-first automation layer for AMD Vivado. It keeps Vivado's native Tcl as the execution layer, adds persistent session artifacts and structured JSON output. MCP support has been removed; the product boundary is now the vivado-cli command and the Vivado Tcl bridge.

The first design target is not GUI click automation. The preferred interactive mode is a managed Vivado Tcl session that can open the GUI with start_gui, load a small Tcl bridge, and let vivado-cli submit audited Tcl command files into that same Vivado process. Batch mode remains useful for CI and fallback automation.

Current design documents:

• Vivado CLI Design
• ADR 0001: Control Vivado through Tcl batch mode
• ADR 0002: Support managed GUI Tcl sessions
• ADR 0003: Support trusted-local raw Tcl
• ADR 0004: Provide built-in help and skills
• ADR 0005: Remove MCP adapter and standardize on CLI
• Built-in Skills

Initial scope

• Discover a local Vivado installation and report its version.
• Start and stop a managed Vivado Tcl/GUI session.
• Verify whether a requested GUI session has a visible Vivado window without stealing focus, and bring that window forward only when explicitly requested.
• Submit raw Tcl to a managed session when trusted-local expert mode is enabled.
• Create or open project-mode Vivado projects.
• Add RTL/source/constraint files with path validation.
• Audit and manage Vivado filesets (sources / simulation / constraint sets) including include directories, defines, libraries, file properties, top module, USED_IN scopes, dry-run plans, and XDC reorder suggestions.
• Apply structured source-fileset and constraint-set changes with optional before/after state diffs.
• Audit XDC constraint filesets: loading order, per-file command markers, USED_IN scopes, methodology markers, and basic UG903/UG949 sanity warnings.
• Search, dry-run/create, inspect, check upgrade state, upgrade, and generate output products for Vivado project IP.
• Audit simulation setup, dry-run/prepare simulation filesets, launch Vivado simulation, and parse xsim/xelab/xvlog/xvhdl logs into issue IDs.
• Create, inspect, audit, dry-run/mutate, validate, and generate generic IP Integrator block designs.
• Run synthesis, implementation, and bitstream generation.
• Run Non-project Mode flows with audit/dry-run support: read RTL/XDC, check prerequisites, execute synth/opt/place/route, write checkpoints, and collect reports.
• Generate timing, utilization, DRC, methodology, power, CDC, bus-skew, clock-interaction, and message reports.
• Parse common report outputs into structured summaries and aggregate report diagnostics with issue IDs, root-cause hints, quality gates, next-action plans, and official-document queries.
• Perform explicit hardware access for hw_server targets/devices, debug core/probe discovery, VIO probe readback, generic ILA capture/CSV analysis, and VIO-backed SPI register readback; hardware programming remains out of scope for structured commands.
• Capture JSON state snapshots and diff project/fileset/constraint/IP/BD/run/report state before and after risky or long-running operations.
• Store logs and generated reports as session artifacts.
• Provide built-in help/skills so AI or human CLI callers can learn the intended Vivado workflows before acting.
• Package AMD official Vivado documentation metadata and topic guidance as the authority layer for help and expert Tcl planning.

Capability profiles

• safe: workflow tools only; no raw Tcl.
• trusted-local: workflow tools plus raw Tcl/source-file execution inside the managed Vivado session.
• unrestricted: raw Tcl with minimal policy checks for personal local use.

The packaged bridge in src/vivado_cli/assets/cli_bridge.tcl is the core control path: vivado-cli submits Tcl files to a live Vivado Tcl/GUI session and receives result files back.

Built-in help

The CLI exposes tutorial and authority content through JSON commands:

• vivado-cli help topic <topic>
• vivado-cli assist next --goal "<task>"
• vivado-cli skills list
• vivado-cli skills get <skill_id>
• vivado-cli tools list
• vivado-cli tools describe <command-or-tool-id>
• vivado-cli tcl help <command>
• vivado-cli tcl review --file <script.tcl>

Seed skill docs live in docs/skills.

The official reference layer stores document IDs, AMD URLs, scope summaries, topic routing, and local filename candidates. It does not copy the full AMD document text into this repository.

Install For Local Use

From a fresh clone:

git clone https://github.com/Shanqianlvshui/Vivado_CLI.git
cd Vivado_CLI
python -m venv .venv
.\.venv\Scripts\python.exe -m pip install -e ".[dev]"

Basic smoke checks after installation:

.\.venv\Scripts\vivado-cli.exe --help
.\.venv\Scripts\vivado-cli.exe tools list
.\.venv\Scripts\vivado-cli.exe tcl help create_clock

This machine has been tested with:

C:\AMDDesignTools\2025.2.1\Vivado\bin\vivado.bat
C:\Xilinx\Vivado\2023.1\bin\vivado.bat

Vivado discovery checks, in order: explicit --vivado-path, VIVADO_BIN (including persisted Windows user/machine environment variables), vivado on PATH, then common Windows installs such as C:\AMDDesignTools, C:\AMD\Vivado, and C:\Xilinx\Vivado. Common installs are sorted newest version first.

The stable local entry point for agents and external tools is:

C:\Tools\vivado-cli\bin\vivado-cli.exe

New terminals can also read the full path from:

$env:VIVADO_CLI_EXE

Fresh Clone Verification

To verify the published repository from scratch, run:

powershell -ExecutionPolicy Bypass -File .\scripts\verify-cold-clone.ps1

The default smoke path clones https://github.com/Shanqianlvshui/Vivado_CLI.git, installs the editable package in a temporary virtual environment, runs CLI help and tool-discovery checks, compiles src and tests, and runs the fast fake-Vivado smoke tests. Add -Full to run the full unit suite in the cold clone.

CLI Usage

vivado-cli is the primary entry point. It writes persistent session records under .vivado_cli/sessions, so separate CLI invocations can operate the same live Vivado process.

The run status and run progress responses expose needs_refresh, is_current, and is_stale. A Vivado status containing Complete is not treated as reusable when the run is stale.

Environment

VIVADO_CLI_WORKSPACE is the default workspace for managed sessions. VIVADO_CLI_ALLOWED_ROOTS is a semicolon-separated list on Windows; workflow paths such as projects, sources, constraints, and Tcl files in trusted-local mode must stay under one of these roots. VIVADO_CLI_DOCS_ROOT points to the local AMD Vivado documentation library used by the official-reference index; it defaults to C:\Database\domains\fpga\xilinx\vivado\docs\raw. Set VIVADO_CLI_PDFTOTEXT if pdftotext is not on PATH.

AI Operating Flow

CLI callers should use this order:

1. Start with vivado-cli assist next --goal "<task>" and include --session, --last-error, or a Tcl draft with --tcl / --file when available.
2. Discover the available surface with vivado-cli tools list, vivado-cli tools describe <command>, vivado-cli skills list, and vivado-cli skills get <skill_id>.
3. Use vivado-cli tcl help <command> before unfamiliar Vivado Tcl; it combines official-document search, CLI coverage guidance, and optional installed Vivado help when a session is attached.
4. Use structured commands first: project summary, fileset ..., constraint ..., bd ..., run ..., report, and hw ....
5. Use vivado-cli tcl review before raw expert Tcl, then vivado-cli session run-tcl or vivado-cli session source-tcl only when no structured command covers the task.
6. Pass explicit acknowledgements for risky actions, such as --expect-destructive, --expect-hardware-access, and --expect-vio-write.
7. Read state_tracking and state_diff from mutating fileset/constraint commands before launching long runs or handing the session to another agent.
8. For a resumed or stale thread, run vivado-cli session recovery, then inspect session timeline, session artifacts, or session read-artifact before changing Vivado state.
9. After mutating project state, refresh with vivado-cli project summary, vivado-cli fileset describe, vivado-cli constraint check-order, vivado-cli bd summary, or vivado-cli run diagnose as appropriate.

First Manual Test

Use this sequence:

1. vivado-cli help topic gui-session
2. vivado-cli tools list
3. vivado-cli check-installation
4. vivado-cli session start
5. vivado-cli session state --session <session_ref>
6. vivado-cli tcl help create_project
7. vivado-cli tcl review --tcl "return \"version=[version -short]\""
8. vivado-cli session run-tcl --session <session_ref> --tcl "return \"version=[version -short]\""
9. vivado-cli project summary --session <session_ref> after opening or creating a project
10. vivado-cli session stop --session <session_ref>

Implemented CLI Commands

Use vivado-cli tools list as the source of truth. The current top-level groups are:

• check-installation
• session start|adopt|list|state|artifacts|timeline|read-artifact|recovery|open-project|run-tcl|source-tcl|stop
• tcl help|review
• skills list|get
• help topic
• assist next
• tools list|describe
• project summary
• fileset list|describe|create|add-files|remove-files|set-file-properties|set-top|apply
• constraint diagnostics|check-order|apply
• bd summary|validate
• run status|progress|launch|launch-local|logs|diagnose|reset
• report
• hw list-debug-cores|vio-read|vio-write|capture-ila|spi-read

Development Checks

.\.venv\Scripts\python.exe -m compileall -q src tests
.\.venv\Scripts\python.exe -m pytest tests\unit -q

The test suite includes a fake Vivado process and CLI lifecycle tests. GitHub Actions runs the same package install, compile check, CLI smoke, and full unit suite on windows-latest.

Artifacts

Command files, result files, logs, and reports are stored under the managed session directory and exposed through artifact URIs:

vivado://sessions/{session_ref}/artifacts/{artifact_id}

Use vivado-cli session artifacts --session <session_ref> to list artifact IDs and vivado-cli session read-artifact --session <session_ref> <artifact_id> to read a bounded text slice. vivado-cli session recovery --session <session_ref> returns the latest analyses, snapshots, quality gates, timeline preview, and next CLI actions for AI handoff and long-running task recovery.

Commands that generate reports, summaries, captures, snapshots, or diffs return filesystem paths and vivado://... artifact URIs in their JSON output. Structured fileset and constraint mutations attach state_tracking and state_diff by default; pass --no-state-diff only for intentional bulk edits where speed matters more than immediate audit artifacts.

Official Reference Resources

Use vivado-cli tcl help <command> for Tcl command routing. It searches the local AMD/Xilinx documentation library when available, reports the official-doc topic, shows any structured CLI coverage for that command family, and can also query installed Vivado help when --session <session_ref> is supplied.

The CLI uses the local PDF library under C:\Database\domains\fpga\xilinx\vivado\docs\raw by default. Set VIVADO_CLI_DOCS_ROOT to another documentation root and VIVADO_CLI_PDFTOTEXT if pdftotext is not on PATH.

Explicitly out of scope for the first version

• GUI click automation.
• Attaching to an arbitrary already-open Vivado process that did not load the CLI bridge.
• Hardware programming, configuration-memory writes, boot operations, and debug/probe mutation. Read-only hardware discovery is supported with explicit confirmation.
• Advanced IP Integrator automation beyond the generic BD action model.
