Hi All, 

 

I need to declare the following Look Up Table: 

 

.......C2 .. C1 .. C0 

L0....t0 ... t1 ... t2 

L1....t2 ... t1 ... t0 

L2....t1 ... t0 ... t2 

 

where t0, t1 and t2 are enum elements of the LUT. 

 

Each element of the LUT should be referenced by (L*,C*), which are also of enum type. 

 

Ex: 

LUT(C2,L0) should refer to t0 

LUT(C1,L1) should refer to t1 

LUT(C0,L2) should refer to t2 

 

So, how should I define this LUT? How should I refer the elements in the LUT? 

 

Thank you!
