routeDesignPartialNonTimingDriven

public static Design routeDesignPartialNonTimingDriven(Design design,
                                                       Collection<SitePinInst> pinsToRoute)

Routes a design in the partial non-timing-driven routing mode.

Parameters:

design - The Design instance to be routed.

pinsToRoute - Collection of SitePinInst-s to be routed. If null, route all unrouted pins in the design.

routeDesignPartialNonTimingDriven

public static Design routeDesignPartialNonTimingDriven(Design design,
                                                       Collection<SitePinInst> pinsToRoute,
                                                       boolean softPreserve)

Routes a design in the partial non-timing-driven routing mode using CUFR.

Parameters:

design - The Design instance to be routed.

pinsToRoute - Collection of SitePinInst-s to be routed. If null, route all unrouted pins in the design.

softPreserve - Allow routed nets to be unrouted and subsequently rerouted in order to improve routability.

routeDesignPartialTimingDriven

public static Design routeDesignPartialTimingDriven(Design design,
                                                    Collection<SitePinInst> pinsToRoute,
                                                    boolean softPreserve)

Routes a design in the partial timing-driven routing mode using CUFR.

Parameters:

design - The Design instance to be routed.

pinsToRoute - Collection of SitePinInst-s to be routed. If null, route all unrouted pins in the design.

softPreserve - Allow routed nets to be unrouted and subsequently rerouted in order to improve routability.

routeDesignWithUserDefinedArguments

public static Design routeDesignWithUserDefinedArguments(Design design,
                                                         RWRouteConfig config)

Partially routes all unrouted sinks in a Design instance; fully-routed sinks will have their routing preserved.

Parameters:

design - The Design instance to be routed.

config - The RWRouteConfig instance to use. If null, the design will be routed in the full timing-driven routing mode with default a RWRouteConfig instance. For more options of the configuration, please refer to the RWRouteConfig class.

Returns:

Routed design.

routeDesignWithUserDefinedArguments

public static Design routeDesignWithUserDefinedArguments(Design design,
                                                         RWRouteConfig config,

                                                         boolean softPreserve)

Partially routes all given sinks in a Design instance; fully-routed sinks will have their routing preserved if "softPreserve" is false, otherwise such sinks may be lazily-rerouted when attempting to route other congested sinks.

Parameters:

design - The Design instance to be routed.

config - The RWRouteConfig instance to use. If null, the design will be routed in the full timing-driven routing mode with default a RWRouteConfig instance. For more options of the configuration, please refer to the RWRouteConfig class.

pinsToRoute - Collection of SitePinInst-s to be routed. If null, route all unrouted pins in the design.

softPreserve - Allow routed nets to be unrouted and subsequently rerouted in order to improve routability.

Returns:

Routed design.

routeDesignWithUserDefinedArguments

public static Design routeDesignWithUserDefinedArguments(Design design,
                                                         String[] args,

                                                         boolean softPreserve)

Partially routes all given sinks in a Design instance; fully-routed sinks will have their routing preserved if "softPreserve" is false, otherwise such sinks may be lazily-rerouted when attempting to route other congested sinks.

Parameters:

design - The Design instance to be routed.

args - An array of string arguments, can be null. If null, the design will be routed in the full timing-driven routing mode with default a RWRouteConfig instance. For more options of the configuration, please refer to the RWRouteConfig class.

main

public static void main(String[] args)
