Method Detail

routeClkWithPartialRoutes

public static void routeClkWithPartialRoutes(Net clk,
                                             Map<String,List<String>> routesToSinkINTTiles,
                                             Device device)

Routes a clk enable net with input data.

Parameters:

clk - The net to be routed.

routesToSinkINTTiles - A map storing routes from CLK_OUT to different INT tiles that connect to sink pins of a global clock net.

device - The target device needed to get routing path representation with nodes from names.

symmetricClkRouting

public static void symmetricClkRouting(Net clk,
                                       Device device)

Routes a clock net by dividing the target clock regions into two groups and routes to the two groups with different centroid nodes.

Parameters:

clk - The clock to be routed.

device - The design device.

routeStaticNet

public static void routeStaticNet(Net currNet,
                                  Function<Node,NodeStatus> getNodeState,
                                  Design design,
                                  RouteThruHelper routeThruHelper)

Routes a static net (GND or VCC).

Parameters:

currNet - The current static net to be routed.

getNodeState - Lambda to get a node's status (available, unavailable, already in-use).

design - The Design instance to use.

routeThruHelper - The RouteThruHelper instance to use.
