Vivado Synthesis - Does Vivado Synthesis merge multiple registers that are declared separately and used as the output register bus of a DSP48?

描述

Does Vivado Synthesis merge multiple registers that are declared separately and used as the output register bus of a DSP48?

解决方案

Vivado Synthesis does not support merging registers into the DSP48 if multiple registers are declared separately and are used as the output register bus of a DSP48.

To work around this issue, declare the registers as one register bus rather than declaring them separately.
