A:首先要知道什么是BRAM,就是Block RAM,这些RAM就是分块的,可以当成36kb来使用,也可以当成18kb来使用,如果使用空间小于18kb,也会占用一整个18kb的BRAM。而且还要看使用的位宽和深度,这两个指标综合考虑来计算使用的BRAM的个数。 以7系列为例,每个36Kb BRAM也可以配置成深度×宽度为64K × 1(当与相邻的36KB块...

A Block RAM (sometimes called embedded memory, or Embedded Block RAM (EBR)), is a discrete part of an FPGA, meaning there are only so many of them available on the chip. Each FPGA has a different amount, so depending on your application you may...
自己用verilog代码写的rom或ram会被综合成查找表LUT+REG构建,并没有使用到block memory资源。 资料:https://www.intel.com/content/www/us/en/programmable/quartushelp/17.0/hdl/vlog/vlog_file_dir_ram.htm ramstyle Verilog HDL Synthesis Attribute
