Start a persistent Vivado TCL session. Must be called before other commands.

Stop the Vivado TCL session and free resources

Get status and statistics of the current Vivado session

Check if Vivado session is responsive and recover if needed. Use this if commands are timing out or behaving unexpectedly.

Get status of this Vivado MCP server host including hostname, free memory, and session state. If free memory is below 64GB, use vivado-snoke instead.

Open a Vivado project (.xpr file)

Close the current project

Get information about the currently open project

Run synthesis on the current project

Run implementation (place and route) on the current project

Generate bitstream for the implemented design

Get timing summary (WNS, TNS, WHS, THS). Returns parsed metrics only by default. Use generate_full_report for raw output.

Get timing paths for failing or critical paths. Returns structured summary (slack, source, dest, clocks) by default. Use generate_full_report for verbose path details.

Get resource utilization (LUT, FF, BRAM, DSP, IO). Returns parsed metrics only by default. Use generate_full_report for hierarchical details.

Get clock information and constraints

Get synthesis/implementation messages (errors, warnings)

Get the design hierarchy (modules and instances)

Get top-level ports of the design

Search for nets in the design

Search for cells (instances) in the design

Execute a raw TCL command in Vivado. Use for advanced operations not covered by other tools.

Launch behavioral simulation (xsim). Opens the simulator and loads the design.

Run the simulation for a specified time

Restart the simulation from time 0

Close the current simulation

Get the current simulation time

Get the current value of a signal in simulation

Get current values of multiple signals matching a pattern

Add signals to the waveform viewer

Set the top module for simulation

List simulation objects (signals, variables) in a scope

List available scopes (hierarchy) in the simulation

Step the simulation by a delta cycle or time step

Add a simulation breakpoint on a signal condition

Remove all breakpoints

Get simulation log messages (errors, warnings, info)

Request a new feature or capability for the Vivado MCP server. Use this when you encounter a limitation or wish you had a tool that doesn't exist.

List all feature requests that have been submitted

Generate a full Vivado report to a file. Use when inline reports are truncated or you need the complete output.
