Blocking: The blocking semantics implies that when the call of a send or receive() primitive blocks the invoker’s current execution. 2. Non-blocking: The non-blocking semantics imply that when the call of a send or receive() primitive does not block the invoker’s current execution and the control immediately goes back to the invoker.

WebJul 3, 2012 · A VHDL variable assignment is working similarly to blocking procedural assignments in Verilog. They also work for synthesis. The main difference is the process local variable scope. "Global variables" exist in VHDL but are rarely supported for synthesis. Don't confuse Verilog blocking assignment with continuous assignments.

WebThe concept of Blocking vs. Nonblocking signal assignments is a unique one to hardware description languages.
