Abstract
Propagating an error through a network includes receiving a network having propagation paths and nodes, where a propagation path has one or more nodes and a node is associated with a variable operable to have a value during simulation. A tag of a tag set is assigned to the value. The tag set includes at least two signed tags, positive tag representing a positive error and a negative tag representing a negative error, and an unsigned tag representing an error having an unknown sign. The tag is propagated along the propagation path to yield intermediate tags, where at least one intermediate tag is an unsigned tag formed from at least two signed tags. A final tag is determined in accordance with the intermediate tags in order to propagate an error through the network.
