21.4.12 sd_create_bif_net

Description

This tcl command creates a bus interface (BIF) net in a SmartDesign component. Any net created must be connected to two or more ports/pins using the command “sd_connect_net_to_pins”.

Note: This command is not required to build a SmartDesign component. It is not exported when you select Libero Project - `Export Script File’ or ‘Export Component Description(Tcl)’ on a SmartDesign component. This command is used to manually create a Tcl script and specify a new name to the net that connects two or more ports/pins.

sd_create_bif_net -sd_name {smartdesign component name} \
                  -net_name {net name}
