Returns the named clock specified by an argument.

get_clocks <pattern>

Arguments

pattern

Specifies the pattern to match to the Timer or SmartTime on which a clock constraint has been set.

Supported Families

Fusion, ProASIC3/E, ProASICPLUS, Axcelerator, ProASIC, eX, SX-A

Description

• If this command is used as a –from argument in maximum delay (set_max_path_delay), false path (set_false_path), and multicycle constraints (set_multicycle_path), the clock pins of all the registers related to this clock are used as path start points.

• If this command is used as a –to argument in maximum delay (set_max_path_delay), false path (set_false_path), and multicycle constraints (set_multicycle_path), the synchronous pins of all the registers  related to this clock are used as path endpoints.

Exceptions

• None
