How to deal with this warning?

Hi Dears: I am using EPM7256ATEC144 to do some logics. There is a warning after compilating. This warning is below: "Warning: Macrocell buffer inserted after node "true_trig_in[12]"...

Can you add a macrocell buffer to the other paths too?

it looks like a 'pin locking' problem. No enough routing resources and a particular signal needs to pass through a macrocell in order to reach a particular pin.

Hope it helps.
