What is the diff b/w blocking & Non-bolcking statements?... Where v r using these types?..
 

In Non-Blocking mode all command,(statement) in block run parallely (all lines Begin to run at same instance)But in Blocking mode line running step by step.(line 2 in this block will run after finishing first line functionality and so on...)

no-block is used for sequential logic . block is used for combinational logic.
