21.4.28 sd_disconnect_pins

Description

This Tcl command disconnects a list of SmartDesign top level ports and/or instance pins from the net they are connected to.

Note: This command is not required to build a SmartDesign component. It maps to an interactive user action in the SmartDesign Canvas and will not be present in the exported file when user selects Libero Project -'Export Component Description(Tcl)' on a SmartDesign component.

sd_disconnect_pins -sd_name {smartdesign component name} \
                   -pin_names {port or pin or slice names}

Arguments


Parameter	Type	Description
sd_name	string	Specifies the name of the SmartDesign component. It is mandatory.
pin_names	string	Specifies the port, pin and/or slice names to be disconnected as follows: {"instance_name:pin_name" "port_name"}. This command will fail if the ports, pins and/or slices do not exist. There may be multiple `-pin_names` arguments (see example below). This is mandatory.


Return Type	Description

Example

The following command disconnects "B_ren" and "B_ADRR[12:12]" slice from the "SD1" design:

sd_disconnect_pins -sd_name {SD1} \
                   -pin_names {B_ren RAM1K20_0:B_ADRR[12:12]}

The following command disconnects "AND2_0:B", "AND3_0:APF_XCVR_ERM_C0_0:LANE0_RX_READY" pin/ports from the "SD2" SmartDesign:
```
sd_disconnect_pins \
      -sd_name {SD2} \
      -pin_names {AND2_0:B AND3_0:APF_XCVR_ERM_C0_0:LANE0_RX_READY}
```
