Field Detail

BUILD_ROUTING_GRAPH_ON_EXPORT

public static boolean BUILD_ROUTING_GRAPH_ON_EXPORT

By default, routing for physical nets will be written as a list of (connected) trees of routing resources. Disabling this feature will save runtime but write out the same set of routing resources as an unordered list of stubs instead.

VERBOSE_PHYSICAL_NET_ROUTING

public static boolean VERBOSE_PHYSICAL_NET_ROUTING

The Interchange format allows for all physical routing resources to be specified, e.g. ... -> PIP -> SitePin -> BELPin(output) -> BELPin(input) -> SitePIP -> BELPin(output) -> BELPin(input) It may not be necessary to use specify all such resources, as many are implied: ... -> PIP -> SitePin -> (implied) -> (implied) -> SitePIP -> (implied) -> (implied) Disabling this flag allows such implied resources to be omitted.
