# Allow simple ECO changes.
#
# This userware assist the user to do ECO changes. The Popup menu is
# extended to perform the following operations on insts/pins:
#
# ```
# Disconnect - Disconnect a pin from a net.
# Connect - Connect a pin to a net.
# Change Connections - Change all connections of an instance.
# Change Cellref - Change the cell referenced by an instance.
# Replace Instance - Replace an instance by an instance of an other
# cell.
# ```
#
# For each operation a string with the performed action is printed to the
# Console window. Instead of this text a DC-script could be created to
# perform the ECO action on the netlist.
