Abstract: Techniques are disclosed relating to detecting and minimizing timing problems created by clock domain crossing (CDC) in integrated circuits. In various embodiments, one or more timing parameters are associated with a path that crosses between clock domains in an integrated circuit, where the one or more timing parameters specify a propagation delay for the path. In one embodiment, the timing parameters may be distributed to different design stages using a configuration file. In some embodiments, the one or more parameters may be used in conjunction with an RTL model to simulate propagation of a data signal along the path. In some embodiments, the one or more parameters may be used in conjunction with a netlist to create a physical design for the integrated circuit, where the physical design includes a representation of the path that has the specified propagation delay.

Abstract: Described are a system and method for managing a data exchange in a network environment. A flowtag is assigned to a data packet at a source device. The flowtag includes a port identification corresponding to a port at an aggregation device. A destination device is in communication with the port at the aggregation device. The data packet is authenticated at the aggregation device. The data packet is output from the source device to the destination device via the aggregation device according to the port identification in the flowtag of the authenticated data packet.
