Simulation and Synthesis Techniques for Asynchronous

异步FIFO的经典设计。 An interesting technique for doing FIFO design is to perform asynchronous comparisons between the FIFO write and read pointers that are generated in clock domains that are asynchronous to each other. The asynchronous FIFO pointer comparison technique uses fewer synchronization flip-flops to build the FIFO. The asynchronous FIFO comparison method requires additional techniques to correctly synthesize and analyze the design, which are detailed in this paper.
