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.

2. Some roads are snakes

3. Some mountains are trees

A) Only 1 follows	B) Only 2 follows
C) Only 3 follows	D) Both 1 and 2 follow

Answer & Explanation Answer: C) Only 3 follows

Explanation:

All snakes are trees. Some trees are roads.

Since the middle term is not distributed even once in the premises,so no conclusion follows

Some trees are roads. All roads are mountains

Since one primise is particular,the conclusion must be particularand should'nt contain the middle term. So,it follows that 'Some trees are mountains'. 3 is the converse of this statement and so it holds.

All snakes are trees. Some trees are mountains.

Since the middle term is not distributed even once in the preises, so no definite conclusion follows
