我使用vivado2018.3配合modelsim 10.6d仿真，未出现你描述的现象。
Parameterized Macro: AXI Memory Mapped (AXI Lite) FIFO MACRO_GROUP: XPM MACRO_SUBGROUP: XPM_FIFO Introduction This macro is used to instantiate AXI Memory Mapped (AXI Lite) FIFO. AXI4 FIFO is derived from the XPM_FIFO_SYNC and XPM_FIFO_ASYNC. The AXI interface protocol uses a two-way ...

一、概述 软件:vivado 器件:vu9p参考文档:ug974简介:XPM,XilinxParameterizedMacros,赛灵思参数化宏,其实就是类似“原语”调用那样,vivado会直接将其识别为对应的模块(目前有CDC跨时钟处理器,FIFO以及BRAM三种) 二、快速上手 步骤如下: 1新建工程及.v文件xpm_async_fifo.v 2.找到 ...
