The base functionality to delay packets is implemented in the abstract MemDelay class. This class exposes three methods that control packet delays: * delayReq(pkt) * delayResp(pkt) * delaySnoopResp(pkt) These methods should be specialized to implement delays for specific packet types. The class SimpleMemDelay uses the MemDelay base class to implement constant delays for read/write requests and responses. The intention is that these classes can be used for rapid prototyping of components that add a small fixed delay and the same throughput as the interconnect. I.e., any buffering done in the base class will be small and proportional to the introduced delay.
