Tcl Commands for General Usage

device_family_name specifies the device family to use with the current ISE project.

Example:

% project set family Virtex2p

 

 

Description:

In this example, the device family for the current project is set to

 

Virtex2p.

 

 

Tcl Return:

The previous value. In this example, the previous device family

 

setting is returned.

 

 

set package (set device package)

The project set package command specifies the device package for the current ISE project.

Note: A list of available devices can be viewed in the Project Properties dialog box in Project Navigator, or by utilizing the unique prefixes supported by Xilinx Tcl commands. For example, type project set device V to get an error message that enumerates all Virtex devices. Optionally, you can specify the partgen –archcommand. From the Tcl prompt (%), type partgen –hfor help using this command.

% project set package <package_name>

project is the name of the Xilinx Tcl command.

set package is the name of the project subcommand.

package_name specifies the target device package for the current ISE project.

Example:

% project set package fg256

 

 

Description:

In this example, the device package for the current project is set to

 

fg256.

 

 

Tcl Return:

The previous value. In this example, the previous device package

 

setting is returned.

 

 

set speed (set device speed)

The project set speed command specifies the device speed for the current ISE project.

Note: A list of available devices can be viewed in the Project Properties dialog box in Project Navigator, or by utilizing the unique prefixes supported by Xilinx Tcl commands. For example, type project set device V to get an error message that enumerates all Virtex devices. Optionally, you can specify the partgen –archcommand. From the Tcl prompt (%), type partgen –hfor help using this command.

% project set speed <speed_grade>

project is the name of the Xilinx Tcl command.

set speed is the name of the project subcommand.
