RouteNodeType.NON_LOCALare the single, double, quad, long wires that travel between INT tiles, along with the uphill muxes (e.g.INT_NODE_SDQ_*) that feed them.RouteNodeType.LOCALis everything else (e.g.INT_NODE_IMUX_*) that is used to connectNON_LOCALto sinks.This PR optimizes the rather messy #893 that kept a set of wire indices that were allowed to be used. Now,
RouteNode.typeindicates whether a node is local or non-local, with the idea that you should only leave your non-local node onto a local one if you are in the vicinity of the sink, since once you are a local node you cannot use a non-local node again (unless LUT routethrus are considered).Furthermore:
RouteNodeType.PINFEED_Ois nowEXCLUSIVE_SOURCERouteNodeType.PINFEED_Iis nowEXCLUSIVE_SINKRouteNodeType.PINBOUNCEhas been merged intoLOCALRouteNodeType.LAGUNA_Iis nowLAGUNA_PINFEEDRouteNodeType.WIREis split intoLOCALandNON_LOCALAlso expand the node reachability tests for US, US+, and Versal.
