very strange QuartusII 7.1 synthesis Tool results

Hi Brad,

Thanks for a quick reply. in my case, APBS1, APBS2 and APBS3 are different modules but with same logic inside. I understand that logic can be shared.

But how can you exaplain me this situation :

case (A)

logic.....

1) A = {a3,a2,a1}

2) A = {a1,a3,a2}

3) A = {a2,a1,a3}

where either a1, a2 or a3 can be high but not all or two at time being how.

I expect that all the three cases must produce the same results.

Regards,

Anil
