almost full 、full、overflow:写入 15个数据后 full 拉高,在第14个数据时 almost full 拉高,若写满后 wr_en 仍为高电平(继续写入),则 overflow 拉高,表示溢出。改代码使写满后wr_en为低电平,则 overflow 始终为低电平,见下两图对比 。 此FIFO 设置深度时设为 16,实际上,从仿真结果看,仅写入15个数据就...
以可编程满阈值为例,假如在单可编程满阈值类型下,写深度为 32,而我们将满阈值有效值设置为28,那么 prog_full 信号将会在 FIFO 中的 数据>=28 后的第一个写时钟上升沿置高,直到 FIFO 内部写数据 个数<28 后的第一个写时钟上升沿拉低。 3.1.4、“Data Counts(数据计数)”选项卡下各参数配置 接下来我们...
almost_fullOutputAlmost Full:When asserted,this signal indicates that only one more write can be performed before the FIFO is full.将满信号,它和满信号full的差别在于一个数据,如果满信号在写进16个数据后会拉高,那么将满信号在写进15个数据后会拉高。 prog_fullOutputProgrammable Full: This signal is ...

TIP: If you only want to connect to your lab machine remotely, you do not need to install the full Vivado design suite on that remote machine. Instead, you can install the light-weight Vivado Hardware Server (Standalone) tool on the remote machine. UG908 (v2022.2) October 19, 2022 ...
