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?
