Vivado Synthesis does not infer DSP48 for a constant multiplier by default
描述
Vivado Synthesis does not infer DSP48 blocks for a constant multiplier by default.
Is this supported?
解决方案
Constant Multiplier is intentionally not mapped into DSP48 by default because DSP48 is not always the best choice for constant multiplier from a timing perspective.
If you want to force DSP48 inference for a constant multiplier, use the attribute use_dsp48 = "yes".
