The main difference betwixt the blocking and non-blocking assignment is that, in the blocking assignment, the rhs immediately gets assigned to the lhs, whereas for the nonblocking designation, the assignment to the lhs is scheduled after the rhs is evaluated.
The example of rhs and then you need to usance of assignments tush use non blocking.
They don't block the execution of the statement following them.

How is blocking assignment statement assigned in Verilog?
Verilog Blocking & Non-Blocking. Blocking. Blocking assignment statements are assigned using = and are executed one after the other in a procedural block. However, this will not prevent execution of statments that run in a parallel block. Note that there are two initial blocks which are executed in parallel when simulation starts.
What's the difference between blocking and non blocking in Verilog?
The blocking vs non-blocking is so that your gate level (synthesis) matches your RTL simulation. Using a different one to alter the behaviour of the simulation as far as I know will not effect synthesis and therefore the behaviour of gate-level.
When to use a D-latch in Verilog?
A variable getting synthesized to a register (latch or flip-flop) vs. combinatorial logic depends on the sensitivity list of the always block. It does not depend on use of blocking or non-blocking assignment. This will result in a D-latch since assignment to q is not specified for when enable==0 so it needs to remember is last assignment.
What's the difference between blocking and nonblocking assignments?
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)

Bottommost line: wire and blocking assignments ar linked together, where reg and non-blocking assignments are connected to get letter a good design stylish hardware circuitry.
As letter a result, changes to our signals don't occur immediately aft assignment but ar instead scheduled to occur at whatever point in the future.
