Syntax

report_route_status [‑return_nets] [‑return_string] [‑file <arg>] [‑append]
    [‑of_objects <args>] [‑route_type <arg>] [‑list_all_nets] [‑show_all]
    [‑dump_routes] [‑has_routing] [‑boolean_check <arg>] [‑ignore_cache]
    [‑quiet] [‑verbose]

Usage

Name	Description
`[-return_nets]`	Return a list of nets that match the given -route_type type
`[-return_string]`	Set the result of running the report in the Tcl interpreter's result variable
`[-file]`	Filename to output results to. (send output to console if -file is not used)
`[-append]`	Append the results to file, don't overwrite the results file
`[-of_objects]`	Report detailed routing for these routes
`[-route_type]`	Only show routes with the given status: UNPLACED\|UNPLACED_ALL\|UNROUTED\|PARTIAL\|GAPS\|CONFLICTS\|ANT ENNAS\|NODRIVER\|MULTI_DRIVER\|LOCKED_NODES\|HAS_ROUTING\|INTR ASITE\|NOLOADS\|HIERPORT\|ROUTED (ignored if -of_objects is used)
`[-list_all_nets]`	list full route information for every net in the design (ignored if -of_objects is used)
`[-show_all]`	list all relevant pins for routes marked as UNPLACED or PARTIAL routes and list all relevant nodes for routes marked as ANTENNAS or CONFLICTS routes (by default only the first 15 pins or nodes are listed for a route)
`[-dump_routes]`	show the full routing tree for every routed net in the design. This is VERY VERBOSE.
`[-has_routing]`	returns 0 if there is no routing currently stored for this design and 1 if there is. All other options are ignored.
`[-boolean_check]`	returns 1 if the given flag is true and 0 if it is not. Value flags that can be checked are: PLACED_FULLY\|PARTIALLY_ROUTED\|ROUTED_FULLY\|ERRORS_IN_ROUT ES. All other options are ignored (cannot be used with -has_routing).
`[-ignore_cache]`	throw away all cached information and recalculate the route status for the entire design (slow)
`[-quiet]`	Ignore command errors
`[-verbose]`	Suspend message limits during command execution

Description

Reports the state of routing in the current design.

The route status report can include a wide range of information, from a simple 1 if the design has routing, to a complete route tree for each net in the design.

Arguments

-return_nets - (Optional) Returns a list of nets that can be processed by other Tcl commands. When the -return_nets argument is used, it is required to also use the -route_type argument with a valid route state.

Note: This argument cannot be used with -return_string, -of_objects, -list_all_nets, -dump_routes, -has_routing, or -boolean_check arguments. This argument will not generate the report_route_status output.

-return_string - (Optional) Directs the output to a Tcl string rather than to the standard output. The Tcl string can be captured by a variable definition and parsed or otherwise processed.

Note: This argument cannot be used with the -file option.

-file <arg> - (Optional) Write the report into the specified file. The specified file will be overwritten if one already exists, unless -append is also specified.

Note: If the path is not specified as part of the file name, the file will be written into the current working directory, or the directory from which the tool was launched.

-append - (Optional) Append the output of the command to the specified file rather than overwriting it.

Note: The -append option can only be used with the -file option.

-of_objects <args> - (Optional) Report the full routing tree for the specified route, net, or xdef_net objects.

Note: The -of_objects option requires objects to be specified using the get_* commands, such as get_cells or get_pins, rather than specifying objects by name. In addition, -of_objects cannot be used with a search <pattern>.

-route_type <arg> - (Optional) Only show routes with the specified route status. Valid route states are:

ANTENNAS - the net has antennas or islands. Antennas are connected routing that don't go to a valid load, islands are pieces of disconnected routing in the route tree.
CONFLICTS - the net has conflicts (either multiple routes share the same node, or a site internally has a logical net driving a site pin and that site pin has routing to it from a different logical net, or a routed site reported that it was invalid).
HIERPORT - the net has either no loads or no drivers and is also connected to a top level terminal port.
INTRASITE (or INTERNAL) - is fully routed inside a site. No routing required.
GAPS - the net has known gaps in the route tree.
HAS_ROUTING - the net has a route tree associated with it.
LOCKED_NODES (or FIXED) - the net has locked routing nodes in it.
NODRIVER (or NO_DRIVERS) - the net has no drivers.
NOLOADS (or NO_LOADS) - the net has no loads and so needs no routing.
PARTIAL - the net has routing but is not fully routed.
ROUTED - the net is fully routed with no errors.
UNPLACED (or UNPLACED_PINS) - the net has any unplaced pins.
UNPLACED_ALL - none of the pins for the net are placed.
UNROUTED - the net needs to be routed but has no route data.

Note: The -route_type option is ignored if -of_objects is also specified.

-list_all_nets - (Optional) Report summary route status for every net in the design, or those selected by -route_type if it is given.

Note: This option is ignored if -of_objects is specified.

-show_all - (Optional) Report all relevant pins for routes marked as UNPLACED or PARTIAL routes and list all relevant nodes for routes marked as ANTENNAS or CONFLICTS routes. As a default only the first 15 pins or nodes are listed for a given route.

-dump_routes - (Optional) Report the full routing tree for every routed net in the design.

Note: This is a very long report, and can take some time to generate.

-has_routing - (Optional) Returns false (0) if the design is unrouted, and returns true (1) if the design has routing. All other options are ignored when -has_routing is specified.

Note: Has routing does not mean fully routed.

-boolean_check <arg> - (Optional) Returns 1 if the specified design attribute is true, and returns 0 if it is not true. Design attributes that can be checked include: PLACED_FULLY, PARTIALLY_ROUTED, ROUTED_FULLY, ERRORS_IN_ROUTES.

Note: This option cannot be used with -has_routing or -return_nets.

-ignore_cache - (Optional) By default the report_route_status command is iterative, and only updates the route information for new nets and routes as the design is implemented. This argument will cause the command to ignore the cached information and regenerate the report for the entire design.

-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.

Examples

The following example reports the route status for the specified nets:

report_route_status -of_objects [get_nets u4*]

The following example returns a list of nets that have routing but are not fully routed to the Find Results window in the Vivado IDE.

show_objects [report_route_status -return_nets -route_type PARTIAL]
