Show netlist items in schematic view

Syntax

show_schematic [‑add] [‑remove] [‑regenerate] [‑pin_pairs] [‑name <arg>]
    [‑quiet] [‑verbose] <objects>

Usage

Name	Description
`[-add]`	Add to existing schematic view
`[-remove]`	Remove from existing schematic view
`[-regenerate]`	Regenerate layout of schematic view
`[-pin_pairs]`	objects are treated as pair of connected pins. This can be useful to display paths
`[-name]`	Schematic window title
`[-quiet]`	Ignore command errors
`[-verbose]`	Suspend message limits during command execution
`<objects>`	Netlist items to show in schematic view

Description

Create a schematic view containing the specified design objects when the tool is invoked in GUI mode.

The scope of the schematic that is displayed depends on the objects specified. A schematic created with cells, shows the specified cells and any connections between the cells. A schematic created with pins, shows the pin objects, or shows them connected as appropriate if -pin_pairs is specified. A schematic created with nets shows the nets, as well as the cells and ports connected to the nets.

To display a schematic with multiple levels of hierarchy, use the current_instance command to set the top-level of the hierarchy, or the level of interest, and use the -hierarchical option when specifying design objects with a get_* command.

Note: This command is only useful when run in the Vivado IDE. When run in Tcl or Batch mode the command simply returns without error or comment.

Arguments

-add - (Optional) Add the specified objects to the schematic window.

-remove - (Optional) Remove the specified objects from the schematic window.

-regenerate - (Optional) Regenerate the schematic window.

-pin_pairs - (Optional) When specified with a pair of connected pin objects, the schematic shows the pins and the wire between the pins. When the -pin_pairs option is not specified, or is specified with disconnected pins, the wire is not shown.

-name <arg> - (Optional) Defines a name for the schematic window opened in the GUI. Use this name to add to, remove from, or regenerate the schematic.

-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.

Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.

-verbose - (Optional) Temporarily override any message limits and return all messages from this command.

Note: Message limits can be defined with the set_msg_config command.

<objects> - (Required) The netlist objects to display in the schematic window.

Examples

The following example creates a schematic for the top-level of the design, displaying the nets as well as the ports and cells they connect to:

show_schematic [get_nets]

The following example sets the level of hierarchy of interest, and creates a hierarchical schematic from the current level down:

current_instance A
show_schematic [get_nets -hier]

The following example creates a schematic window showing the specified pins, and the wire connection between them:

show_schematic -pin_pairs [get_pins {data0_i/O data_reg/D}]
