AMBA demonstrates how to create and use an AMBA AHB master. It makes extensive use of Pipeline Boundary Markers in the master transactors which are used to model the pipeline behavior defined by the AMBA specification. "Blocking Samples" in the master write and read transactions are used to wait for HREADY. Loop Markers in the master idle and busy transactors insert variable number of idle or busy cycles. State Variables and "Store Sampled Value As Subroutine Output" variables in the master write transactor are used to pass the read data back to the sequencer process. There is also a User-defined Class Method that determines the burst length based on a given burst code (defined by AMBA spec.). And finally the project makes use of Constrained randomization so that idle and busy transactors are applied using a random number of idle or busy cycles.
