com.xilinx.rapidwright.design.tools.InlineFlopTools

public class InlineFlopTools
extends Object

Set of tools to add/remove flip flops inline to top level port connections. This is targeted at kernel replication preparation prior to routing to ensure that connections are routed outside of the pblock of the out-of-context kernel.

createAndPlaceFlopsInlineOnTopPorts

public static void createAndPlaceFlopsInlineOnTopPorts(Design design,
                                                       String clkNet,
                                                       PBlock keepOut)

Add flip flops inline on all the top-level ports of an out-of-context design. This is useful for out-of-context kernels prior to placement and routing so that after the flops have been placed, the router is forced to route connections of each of the ports to each of the flops. This can help alleviate congestion when the kernels are placed/relocated in context. Note this assumes the design is not implemented as in most contexts it will be placed and routed immediately following this modification.

Parameters:

design - The design to modify

clkNet - Name of the clock net to use on which to add the flops

keepOut - The pblock used to contain the kernel and the added flops will not be placed inside this area.

removeInlineFlops

public static void removeInlineFlops(Design design)

Removes the inline flops added by InlineFlopTools.createAndPlaceFlopsInlineOnTopPorts(Design, String, PBlock)

Parameters:

design - The current design from which to remove the flops

main

public static void main(String[] args)
