Description
For use with the incremental implementation flow, this command reports on the amount of design overlap between the current design and an incremental checkpoint loaded using the read_checkpoint -incremental command.
This report analyzes the loaded incremental checkpoint against the current design to see if the two are sufficiently correlated to drive incremental placement and routing. A low correlation between the current design and the checkpoint should discourage using the checkpoint as a basis for incremental place and route. Refer to the Vivado Design Suite User Guide: Implementation (UG904) for more information on incremental place and route.
If there is a low correlation of reuse between the current design and the loaded incremental checkpoint, you will need to restore the original design using open_run or read_checkpoint. Alternatively, you can overload the incremental checkpoint in the current design by issuing the read_checkpoint -incremental command again to specify a new incremental checkpoint.
For Partial Reconfiguration (PR) designs, the % of cells matching in Reconfigurable Modules (RM) are reported, the % of cells reused in RMs, and the % of cells fixed in RMs are also reported. There is also a Reconfigurable Modules Summary table added to the report.
Arguments
-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. By default, the report will be written to the Tcl console.
-append - (Optional) Append the output of the command to the specified file rather than overwriting it.
-append option can only be used with the -file option.
-cells <args> - (Optional) Specifies the cells to use from the DCP file.
-hierarchical - (Optional) Generate a text-based hierarchical incremental reuse report.
-hierarchical_depth <arg> - (Optional) Specifies the depth level for the text-based hierarchical incremental reuse report. The default is 0.
-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.
-file option.-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.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
