Embedded 更改我的程序的用户逻辑.v
我刚刚在Xilinx中创建了一个自定义IP，它生成了我在Verilog中需要的用户逻辑文件，但是我在更改代码时遇到了问题 我需要的是实现数据到达FSL，执行一些加法，然后将值返回到MicroBlaze，数据正在发送，但现在正在返回Embedded 更改我的程序的用户逻辑.v,embedded,verilog,fpga,xilinx,hdl,Embedded,Verilog,Fpga,Xilinx,Hdl,我刚刚在Xilinx中创建了一个自定义IP，它生成了我在Verilog中需要的用户逻辑文件，但是我在更改代码时遇到了问题 我需要的是实现数据到达FSL，执行一些加法，然后将值返回到MicroBlaze，数据正在发送，但现在正在返回 enter code here //---------------------------------------------------------------------------- // video - modu
