Speedprint Syntax

Use the following syntax to run speedprint:

speedprint [options] device_name

options can be any number of the Speedprint options listed in “Speedprint Options”. They do not need to be listed in any particular order. Separate multiple options with spaces.

Speedprint Options

This section describes the options to the Speedprint command.

–intstyle (Integration Style)

–intstyle {ise xflow silent}

The –intstyle command line option specifies program invocation context. By default, the program is run as a standalone application.

–intstyle ise

Indicates that the program is being run as part of an integrated design environment.

–intstyle xflow

Indicates that the program is being run as part of a batch flow.

–intstyle silent

Indicates that only error messages and warnings will be displayed to the screen.

Note: The -intstyle option is automatically invoked when running in an integrated environment, such as Project Navigator or XFLOW.

–min (Display Minimum Speed Data)

The –min option displays minimum speed data for a device. This option overrides the –s option if both are used.

–s (Speed Grade)

–s[speed_grade]

The –s option with a speed_grade argument (for example, -4) displays data for the specified speed grade. If the –s option is omitted, delay data for the default, which is the fastest speed grade, is displayed.

–t (Specify Temperature)

–ttemperature

The –t option specifies the operating die temperature in degrees Celsius. If this option is omitted, the worst-case temperature is used.
