根据FIFO的实现方式不同,需要加入不同的XDC约束。 Build-in硬核FIFO 这种FIFO实际上就是用FPGA内部的BRAM来搭建,所有控制逻辑都在BRAM内部,是推荐的FIFO实现方式。其所需的XDC也相对简单,只要像上述简单同步器的时钟关系约束一样用set_clock_groups将读写时钟约束为异步即可。 带有格雷码控制的FIFO 为了在亚稳态下做...

In high-level synthesis, arrays are synthesized into block RAM by default, but other options are possible, such as FIFOs, distributed RAM, and individual registers. When using arrays as arguments in the top-level function, high-level synthesis assumes that the block RAM is outside the top-...
