Method Summary

Modifier and Type	Method and Description
static Net	insertFlopChain(Design design, Net net, String clkName, int depth, List<EDIFHierPortInst> portInsts, Set<SiteInst> siteInstsToRoute) Inserts a chain of depth flops between the source of net and portInsts, evenly spaced along the line from the source to the sinks' centroid.
static Net	insertFlopChain(Design design, Net net, String clkName, int depth, List<EDIFHierPortInst> portInsts, Set<SiteInst> siteInstsToRoute, List<RelocatableTileRectangle> noGoBboxes) As FlopTreeTools.insertFlopChain(Design, Net, String, int, List, Set), but the inserted flops will not be placed inside any of noGoBboxes (may be null or empty for no restriction).
static void	insertFlopTreeForNet(Design design, String netName, String clkName, int depth, int maxDepthPerSLR) Inserts a pipelined fanout tree of depth flop levels between the source of netName and all of its sinks.
static void	insertFlopTreeForNet(Design design, String netName, String clkName, int depth, int maxDepthPerSLR, List<RelocatableTileRectangle> noGoBboxes) As FlopTreeTools.insertFlopTreeForNet(Design, String, String, int, int), but the inserted flops will not be placed inside any of noGoBboxes — typically the bounding boxes of placed kernel/array modules, inside which the local INT routing is too congested to escape from a fresh flop's site pin (may be null or empty for no restriction).

Method Detail

insertFlopChain

public static Net insertFlopChain(Design design,
                                  Net net,
                                  String clkName,
                                  int depth,
                                  List<EDIFHierPortInst> portInsts,
                                  Set<SiteInst> siteInstsToRoute)

Inserts a chain of depth flops between the source of net and portInsts, evenly spaced along the line from the source to the sinks' centroid. Returns the net driven by the final flop of the chain.

insertFlopChain

public static Net insertFlopChain(Design design,
                                  Net net,
                                  String clkName,
                                  int depth,
                                  List<EDIFHierPortInst> portInsts,
                                  Set<SiteInst> siteInstsToRoute,
                                  List<RelocatableTileRectangle> noGoBboxes)

As FlopTreeTools.insertFlopChain(Design, Net, String, int, List, Set), but the inserted flops will not be placed inside any of noGoBboxes (may be null or empty for no restriction).

insertFlopTreeForNet

public static void insertFlopTreeForNet(Design design,
                                        String netName,
                                        String clkName,
                                        int depth,
                                        int maxDepthPerSLR)

Inserts a pipelined fanout tree of depth flop levels between the source of netName and all of its sinks. Sinks in other SLRs are reached through SLR-crossing flop chains; within each SLR a quadrant-based tree of at most maxDepthPerSLR levels is built, with any remaining depth inserted as pacing chains.

insertFlopTreeForNet

public static void insertFlopTreeForNet(Design design,
                                        String netName,
                                        String clkName,
                                        int depth,
                                        int maxDepthPerSLR,
                                        List<RelocatableTileRectangle> noGoBboxes)

As FlopTreeTools.insertFlopTreeForNet(Design, String, String, int, int), but the inserted flops will not be placed inside any of noGoBboxes — typically the bounding boxes of placed kernel/array modules, inside which the local INT routing is too congested to escape from a fresh flop's site pin (may be null or empty for no restriction).
