remove_connection (::quartus::eco)

Belongs to ::quartus::eco 1.0

The remove_connection command will disconnect the source signal from the destination block port, and set the input port to a disconnected state.

remove_connection expects a source and destination through: 
from - output net of the source block of the new connection, OR
from_node AND from_port - node ID and output port ID of source

to AND port - name of the destination node and the input port name, OR
to_node AND to_port - node ID and input port ID of the destination

Note:
Connection path containing Hyper Registers is not allowed to be removed.

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

This example will disconnect top|a_out from the D input port of node top|x,
and set top|x:D to a disconnected state.

remove_connection -ARG(from_node) $from_node -ARG(from_port) $oport -ARG(to_node) $to_node -ARG(to_port) $iport

This example iterates over the netlist and node ports, then removes the connection between
the first oport of my_node and the first iport of my_ff
