Virtex6 DSP48 View

Compared to the Virtex5 DSP48 View in ADEPT, the Virtex6 DSP48 View has 5 new columns (circled in the snapshot below) for the new pre-adder in DSP48E1 slice. The INMODE4, INMODE3:0 and USE_DPORT columns display the actual values for the INMODE input and USE_DPORT attribute. The MULT_A and MULT_B columns display inputs to the multiplier A and B ports based on the decoding of INMODE and USE_DPORT.
