can any one tell me what is this error 

 Error: Node instance "Arbiter_1_1" instantiates undefined entity "Arbiter"

[Altera_Forum]

you havent supplied the Aribiter source code.

[Altera_Forum]

arbiter is a component and is declared.....

[Altera_Forum]

You may have decalred it as a component, but it cannot find the entity (ie. the source code for arbiter).

Sir, 

Here is the defination of component 'Arbiter'.  COMPONENT Arbiter PORT(Req, North, West, Mask: IN std_logic; South, East, Grant: OUT std_logic); END COMPONENT;  The instant of above arbiter is called as follows.  Arbiter_1_1: Arbiter PORT MAP (Req => arb_req(1), North => High, West => High, Mask => c_bar_P(7), South => south_2_north(1)(1), East => east_2_west(1)(1) , Grant => arb_grant(1)(1));   and the error is  Error: Node instance "Arbiter_1_1" instantiates undefined entity "Arbiter"

Like I said, that is just the component. 

 You need the source code for the entity.  A component is just a black box until you have an entity to link it to. A component on its own is useless.  Do you not have an arbiter.vhd?

I have no idea how the arbiter is supposed to work. 

So only you can create the arbiter.  Why are you using a component called arbiter if you dont have the source code for it?
