Abstract: Packet format configurability is extended for packets transported on physical links of an Intellectual Property (IP) core interconnect by using at least two independent parameters: one parameter governing data-width and one parameter governing latency penalty. The at least two independent parameters allow creation of transport protocol packets without additional latency insertion, which is useful for low-latency applications. The at least two independent parameters also allow creation of narrow packets with multi-cycle additional latency, which is useful for latency tolerant, area sensitive applications.

Abstract: Verification IPs for the verification of semiconductor chip designs are designed to support specific interface protocols. Verification IP is expensive or unavailable to test devices with interfaces of uncommon protocols. Verification IP that uses a generic interface protocol, used in conjunction with simple adapters between interfaces of the VIP that use the generic protocol and interfaces of the device under test that use specific protocols, are reused to test interfaces with different specific protocols if the generic protocol supports a superset of the features of the specific protocols.

Abstract: A system and method are disclosed for communicating coherency information between initiator and target agents on semiconductor chips. Sufficient information communication to support full coherency is performed through a socket interface using only three channels. Transaction requests are issued on one channel with responses given on a second. Intervention requests are issued on the same channel as transaction responses. Intervention responses are given on a third channel. Such an approach drastically reduces the complexity of cache coherent socket interfaces compared to conventional approaches. The net effect is faster logic, smaller silicon area, improved architecture performance, and a reduced probability of bugs by the designers of coherent initiators and targets.
