Question

我收到以下错误。但我无法从打印的错误消息中了解问题。

生成此错误的代码在这里

//One FIFO at each of the Output
    val fifoClass    = (0 until ports).map(x=>  { Module(new Fifo(0, widthParam, depthParam, ports))}).toList

    for(i<-0 until ports){
        deqWire(i)    := fifoClass(i).io.enqRdy
    }

    //Each iteration represents each FIFO at the output side
    for(i<-0 until ports){
        fifoClass(i).io.enqData    := switchClass.io.outPort(i)
        fifoClass(i).io.deqRdy        := deqWire
    }

Answer 1

问题的核心是你试图将一个Vec（）分配给一个UInt（）。那不行。类型不匹配。

但是还有其他一些问题。首先，您没有向我们显示行号，因此我们无法将错误与代码匹配。您也没有向我们展示deqWire的定义。那是什么类型的东西？

我也不确定你对fifoClass的习语。也许这有效，但我自己已经找到了成功

val my_array_of_modules = Vec.fill(num_elements) { Module (new Thing()).io }

但这可能不是问题。

不确定错误消息试图传达的内容
