Assign Statement : An assign statement is used for modeling only combinational logic and it is executed continuously. So the assign statement is called 'continuous assignment statement' as there is no sensitive list.

. The symbol after reserved word always, indicates that the block will be triggered at the condition in parenthesis after symbol. This is due to the fact that timing analysis tools always have problems with latches glitch at enable pin of latch is another problem).

In any combinational logic, output changes whenever input changes. Combinational circuits modeling in verilog can be done using assign and always blocks. There are two types of sensitive list level sensitive (for combinational circuits) and edge sensitive (for flip-flops).

Normally we use nonblocking assignments for sequential circuits. Dont mix blocking and nonblocking assignments in the same always block (even if design compiler supports them!). Sequential logic circuits are modeled using edge sensitive elements in the sensitive list of always blocks.

One important note about always block it can not drive wire data type, but can drive reg and integer data types. Sequential logic can be modeled only using always blocks. A second difference is that an always block should have a sensitive list or a delay associated with it.

These variables are the ones included in the sensitive list, namely a, b and sel. We normally have to reset flip-flops, thus every time the clock makes the transition from 0 to 1 (posedge), we check if reset is asserted (synchronous reset), then we go on with normal logic. One is combinational circuits and the second is sequential circuits.

One simple way to eliminate the latch with always statement is to always drive 0 to the lhs variable in the beginning of always code as shown in the code below. As the name suggests, an always block executes always, unlike initial blocks which execute only once (at the beginning of simulation). From what we have learnt in digital design, we know that there could be only two types of digital circuits. Below is a small list of guidelines. The code below is the same 21 mux but the output y is now a flip-flop output.

Verilog - Wikipedia
Verilog, standardized as IEEE 1364, is a hardware description language (HDL) used to model electronic systems.It is most commonly used in the design and verification of digital circuits at the register-transfer level of abstraction.

    Normally we use nonblocking assignments for sequential circuits. The above example is a 21 mux, with input a and b sel is the select input and y is the mux output.

Sequential logic circuits are modeled using edge sensitive elements in the sensitive list of always blocks.
