The code would be implemented with a flip-flop, a latch, or a multiplexer. Then the arbiter when the master will be granted to use the bus. The third wire is MOSI (Master Out Slave IN) This wire acts as a carrier which only sends the signals required by the Master to the slave. "cookie-cutter" approach is designed to avoid Verilog's bug-prone areas, while keeping your code as non-verbose as possible. The paper also introduced how to design the AMBA (advanced microprocessors bus architecture) verification IP (intellectual property) by System Verilog, which include AHB (advanced high-performance bus) master and AHB monitor.
