One of the most misunderstood constructs in the Verilog language is the nonblocking
assignment. Even very experienced Verilog designers do not fully understand how nonblocking assignments are scheduled in an IEEE compliant Verilog simulator and do not understand when and why nonblocking assignments should be used. This paper details how Verilog blocking and nonblocking assignments are scheduled, gives important coding guidelines to infer correct synthesizable logic and details coding styles to avoid Verilog simulation race conditions. Cool!
