7.4.2. make_connection

Description

Connects the source signal to the destination block port. If the port has an existing connection, the command removes the previous connection and connects it to the signal you specify. The actual routing change occurs implicitly when appropriate. You can locate node names by right-clicking a node in Netlist Viewer, and then clicking Properties.

make_connection also supports adding connections from and to Hyper-Registers. In the case of Hyper-Registers, the command first disconnects the destination port, before making a new connection. You can the run the make_connection command to specify a replacement signal source or destination.

If a port is shared among multiple RAM slice atoms, then the ECO Fitter automatically updates all relevant atoms, and reports them accordingly.

Usage

The following example connects top|a_out to the D input port of node top|x.

make_connection -from top|a_out -to top|x -port D

Arguments

from
Output net of the source block of the new connection.
to
Name of the destination block.
port
The input port name of the destination block.
