isNodeUsed

public boolean isNodeUsed(Tile tile,
                          int wire)

isNodeUsed

public boolean isNodeUsed(RouteNode routeNode)

markPIPsAsUsed

public void markPIPsAsUsed(ArrayList<PIP> pips)

Examines the pips in the list and marks all of the resources as used.

Parameters:

pips - The PIPs to mark as used.

getSourcesFromPIPs

public ArrayList<RouteNode> getSourcesFromPIPs(ArrayList<PIP> pips)

Creates sources from a list of PIPs

Parameters:

pips - The pips of the net to examine.

Returns:

The list of sources gathered from the pips list.

markNodeUsed

public void markNodeUsed(RouteNode n)

addInitialSourceForRouting

public void addInitialSourceForRouting(SitePinInst currSource)

This will add the sole source of the net to the set of sources to be used by the router. It also updates the Router's currSources with the sole source of the net.
