The "Type" column in the report uses a symbol to indicate what type of delay occurs at that point in the

path.

Possible "Type" values are:

The values of the "-from", "-to", and "-through" options are either collections or a Tcl list of wildcards used

to create collections of appropriate types. The values used must follow standard Tcl or

TimeQuest-extension substitution rules. See the help for use_timequest_style_escaping for details.

Example

project_open my_project

# Always create the netlist first

create_timing_netlist

read_sdc my_project.sdc

update_timing_netlist

# Run a setup analysis between nodes "foo" and "bar",

# reporting the worst-case slack if a path is found.

set my_list [report_timing -from foo -to bar]

set num_paths [lindex $my_list 0]

set wc_slack [lindex $my_list 1]

if { $num_paths > 0 } {

puts "Worst case slack -from foo -to bar is $wc_slack"

}
