21.4.9 sd_connect

Description

This Tcl command connects a list of SmartDesign top level ports and/or instance pins together.

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


Parameter	Type	Description
sd_name	string	Specifies the name of the SmartDesign component. It is mandatory.
pin_names	string	Specifies the port names, pin names and/or slice names to be connected together. It is mandatory. This command will fail if the ports, pins or slices do not exist. This command will also fail if the ports, pins and/or slices are not of the same size/range.


Return Type	Description
None	None


Error Code	Description
None	Cannot connect top-level input port 'port_name' to top-level input port 'port_name' since they are both drivers.
None	Required parameter 'pin_names' is missing.
None	Required parameter 'sd_name' is missing.
None	Parameter 'param_name' is not defined. Valid command formatting is 'sd_connect_pins -sd_name "sd_name" -pin_names "[pin_names]+"'.

The following example connects "CLK" port to "CLK" pins of "MACC_PA_0:CLK" and "DFN1_0:CLK" instances:
```
sd_connect_pins -sd_name {top} \
                -pin_names {CLK MACC_PA_0:CLK DFN1_0:CLK}
```

The following example connects "MACC_PA_0:A" pin to "RAM1K20_0:A_DIN[17:0]":

sd_connect_pins -sd_name {top} \
                -pin_names {MACC_PA_0:A RAM1K20_0:A_DIN[17:0]}
