本仓库的代码逻辑中,每一次突发传输中,只要 wvalid 和 wready 同时为高电平,就触发一次 response。
而 AXI4 接口协议多次强调 response 只能出现在一次写事务结束后(wlast 拉高之后)
是不是实现上有一些问题呢?

你好, 抱歉回复时间稍晚,这段时间我有一些事情。
首先需要明确的是,根据相关逻辑实现,我的确是忽略了WLAST。感谢你的指出。 因为一开始这个IP核是给VexRiscv项目使用的,对于VexRiscv来说并没有使用到WLAST信号,所以这里忽略了这个问题。
你可以自行尝试对代码进行一些修改,并欢迎提交。 若你不熟悉SpinalHDL,则只是修改生成后的verilog也是可以的。我可以尝试将其改为SpinalHDL的实现。
Sorry, something went wrong.
