Spartan6 DSP48 View
Spartan6 DSP48 View (see the first snapshot below. Click on it for full resolution) in ADEPT can be displayed after an NCD is read with "Get DSP48 attributes" checked (see the second
snapshot below). The DSP48 view displays all DSP48 instances in the
design with their placements, major attributes and decoded functions. If OPMODE inputs are not connected to constant 1's or 0's, their
values will have "?" in them. If OPMODE can't be decoded, the
corresponding decoding columns will be blank.
