Q:

What are the blocking and non-blocking assignments in Verilog and which is preferred in Sequential Circutis?

Answer

A blocking assignment is one in which the statements are executed sequentially, i.e., first statement is executed and variable is assigned  a value then second is executed and so on. A non blocking assignment is  one in which statements occurs conturrently, only non blocking assignments should be used in sequential circuit.


 


e.g.


initial


begin


a=b; //blocking


c<=a; //nonblocking


d=c; // blocking


end


 


In this example firstly the value of b is assigned to a and this value is assigned to c only after execution of first statement. the second and the third statements are executed simultaneously, i.e. value a ais assigned to c and previous value if c is assigned to d.
