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}See Also
