A problem about GAL26V12

[Li GenZhu]

I have a very simple design that should fit in a GAL26V12 with ease,
but I keep getting "Design does NOT fit" What's going on?
ABEL Example:
MODULE Test1
CSN pin;
K4,K2,K0,K6,K1,K5,K3,K7 pin;
K = [K0,K1,K2,K3,K4,K5,K6,K7];

D7,D6,D5,D4,D3,D2,D1,D0 pin;
D = [D0,D1,D2,D3,D4,D5,D6,D7];

Equations
D = K;
K.oe = !CSN;
END

This won't fit. and give me as follows messages.

thank all kind friends. Now it is ok,
as you say, D is output, so it ought to be D.oe = !CSN.
thanks a lot.
