使用monitor 1)首先使用item_collected_port.get()获取监控到的数据,这是一个阻塞的函数调用,会一直阻塞直到出现一个传输,所以要放在forever循环中,这里的agent是master,当然slave和passthrough模式的agent同样可以监控到数据,同样的操作依然试用, 2)随后监控到的数据会自动放到axi_monitor_transaction(继承自axi_transactio...

寄存器切片可以添加到 AXI 通道的前向控制路径中,不会造成吞吐量损失。 1.3.8 Single Master System Optimization 当DW_axi 仅配置有一个 AXI 主控时,会自动消除以下不必要的硬件功能: 写数据交织规则 跟踪由从端口生成的活动读/写事务的数量 AXI 锁定规则 当多个主控同时请求时,从端口的读/写地址和写数据通道的...
Note that ECC functionality can be enabled regardless of dual or single port BRAM access. ECC is enabled by configuring the design parameter, C_ECC = 1. Note that ECC is only available (in this release) when the BRAM block is configured to a 32- or 64-bit data width.The LogiCORE® ...
