21.4.14 sd_create_bus_net

Description

This tcl command creates a bus net of a given range 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_bus_net -sd_name {smartdesign component name} \
                  -net_name {net name} \
                  -net_range [left index range:right index range]

Example

This example creates bus net in range [5:0] named "ab1" and connects it to the "RAM64x12_0:R_ADDR" and "a" pins.

This new net is visible in the UI only when it is connected to two or more ports/pins using the command“sd_connect_net_to_pins” as shown below.

sd_create_bus_net -sd_name {top} \
                  -net_name {ab1} \
                  -net_range {[5:0]]}
sd_connect_net_to_pins -sd_name {top} \
                       -net_name {ab1} \
                       -pin_names {a RAM64x12_0:R_ADDR}
