A nonblocking assignment is a verilog adjective assignment that uses the <= hustler inside of A procedural block.
If death penalty of other statements is blocked aft evaluation of far-right hand side of a statement until assignment to far left hand side is done, it is called blocking statement.
The right hand lateral of the affirmation is evaluated forthwith at the opening of the clip step and the assignment is deferred to the conclusion of the clip step.

Therefore, it blocks separate assignments until the current assignment completes and is called as blocking assignment.
- in general, the blocking statements should be used with combinational circuits, and non-blocking statements should be used fashionable sequential circuits.
