Make differential pair for 2 ports
make_diff_pair_ports [‑quiet] [‑verbose] <ports>...
|Ignore command errors
|Suspend message limits during command execution
|Ports to join
Joins two existing ports to create a differential pair. The port directions, interfaces, and other properties must match in order for the specified ports to be joined as a differential pair. Otherwise an error will be returned.
Important: The two ports must first be created, either by using the
create_port command or by reading in an XDC file, prior to making them into a differential pair.
-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the
<ports> - (Required) Two port objects to join as a differential pair. The first port specified will be the positive side of the differential pair.
The following example joins the two specified ports to create a differential pair:
make_diff_pair_ports port_Pos1 port_Neg1
