erro

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?

hello sir...

thank you very much... i have created a entity called arbiter and its working.. but i want to see the RTL output of it .....how to check this in QUARTUS-II
