我正在编写wishbone plumbing package来为我的设计生成Intercon模块。
在名为wbplumbing
的程序包中,我为Wishbone Master和Slave接口声明了两个Bundle:
class WbMaster (val dwidth: Int,
val awidth: Int) extends Bundle {
val adr_o = Output(UInt(awidth.W))
// ...
val cyc_o = Output(Bool())
override def cloneType = (new WbMaster(dwidth, awidth)).asInstanceOf[this.type]
}
// Wishbone slave interface
class WbSlave (val dwidth: Int,
val awidth: Int) extends Bundle {
val adr_i = Input(UInt(awidth.W))
// ...
val cyc_i = Input(Bool())
override def cloneType = (new WbSlave(dwidth, awidth)).asInstanceOf[this.type]
}
我的Intercon模块将这两个Bundles作为参数:
// Wishbone Intercon Pass Trought : one master, one slave
class WbInterconPT (val awbm: WbMaster,
val awbs: WbSlave) extends Module {
val io = IO(new Bundle{
val wbm = Flipped(new WbMaster(awbm.dwidth, awbm.awidth))
val wbs = Flipped(new WbSlave(awbs.dwidth, awbs.awidth))
})
//...
}
我要插入此Intercon的两个模块位于名为spi2wb和mdio的两个不同的程序包中。两者都包含带有捆绑包的wbplumbing软件包:
import wbplumbing.WbMaster
import wbplumbing.WbSlave
然后在我的“顶部”模块上导入:
// spi, mdio bus modules
import wbplumbing.WbInterconPT
import wbplumbing.{WbMaster, WbSlave} // <- not sure that usefull
import spi2wb.{Spi2Wb, SpiSlave}
import mdio.{MdioWb, MdioIf}
并实例化它:
// Wishbone parameters
val dwidth = 16
val awidth = 2
// module instantiation
val spi2Wb = Module(new Spi2Wb(dwidth, awidth))
val wbMdio = Module(new MdioWb(mainFreq, targetFreq))
val wbIntercon = Module(new WbInterconPT(spi2Wb.io.wbm, wbMdio.io.wbs))
然后我得到一个类型错误:
[info] Set current project to spi2ksz (in build file:/pchpch/spi2ksz/)
[info] Compiling 1 Scala source to /pchpch/spi2ksz/target/scala-2.11/classes ...
[error] /pchpch/spi2ksz/src/main/scala/spi2ksz.scala:29:47: type mismatch;

[error] val wbIntercon = new WbInterconPT(spi2Wb.io.wbm, wbMdio.io.wbs)
[error] ^

我确定解决方案非常简单,但是可以找到解决方法!
答案 0 :(得分:2)
好吧,这是一个publishLocal错误。 在设计之初,我在此处分别声明了WbSlave和WbMaster Bundle。然后我出版了。
然后,我编写了WbPlumbing软件包以将其全部整合在一起。而且我忘了在本地“重新”发布两个模块。
有时候,问问题可以解决问题;)
