3.5.1.4. 18 x 19 Multiplication Summed with 36-Bit Input Mode

Cyclone® 10 GX variable precision DSP blocks support one 18 x 19 multiplication summed to a 36-bit input.

Use the upper multiplier to provide the input for an 18 x 19 multiplication, while the bottom multiplier is bypassed. The datab_y1[17..0] and datab_y1[35..18] signals are concatenated to produce a 36-bit input.
