report_partitions

Usage

report_partitions [-nworst <number>] [-panel_name <name>] [-stdout]

Options

-nworst <number>: Specifies the maximum number of paths to report between partitions.

If unspecified, the limit defaults to 1000

-panel_name <name>: Sends the results to the panel and specifies the name of the new

panel

-stdout: Output the result onto stdout

Description

Reports timing information related to design partitions.

The report_partitions command analyzes the worst 1000 setup paths in the design by default, but you can

optionally set the nworst option to increase or decrase this number.

This function reports the total number of failing paths for each partition and the worst-case slack for any

path involving the partition in a Partition Timing Overview table.

The function also creates a Partition Timing Details table that lists the number of failing paths and

worst-case slack from each partition to the others, which provides a more detailed breakdown of where

the critical paths in the design are with respect to design partitions.

Reports can be directed to the Tcl console (-stdout, by default) or the TimeQuest graphical interface

(-panel_name <name>)or both.

Example

project_open my_project

create_timing_netlist

read_sdc

update_timing_netlist

# Report a maximum of 500 failing paths between partitions to the

# TimeQuest graphical interface and to the Tcl console.

report_partitions -panel_name "Partition Timing Report" -nworst 500 \

-stdout
