I. Blocking vs. Nonblocking Assignments • Verilog supports two types of assignments within always blocks, with subtly different behaviors. • Blocking assignment: evaluation and assignment are immediate • Nonblocking assignment: all assignments deferred until all right-hand sides have been evaluated (end of simulation timestep)

Testbench guideline: nonblocking assignments are less streamlined to simulate than blocking assignments; consequently, in general, placing delays on the lhs of nonblocking assignments for either modeling or testbench generation is discouraged.
The stratified event waiting line is a fanciful name for the different verilog case queues that ar used to agenda simulation events.
