QSysify

QSysify is a tool which is able to generate a QSys IP (tcl script) from a SpinalHDL component by analyzing its IO definition. It currently implement the following interfaces features :

Master/Slave AvalonMM
Master/Slave APB3
Clock domain input
Reset output
Interrupt input
Conduit (Used in last resort)

Example

In the case of a UART controller :

case class AvalonMMUartCtrl(...) extends Component {
  val io = new Bundle {
    val bus =  slave(AvalonMM(AvalonMMUartCtrl.getAvalonMMConfig))
    val uart = master(Uart())
  }

  // ...
}

The following main will generate the Verilog and the QSys TCL script with io.bus as an AvalonMM and io.uart as a conduit :

object AvalonMMUartCtrl {
  def main(args: Array[String]) {
    // Generate the Verilog
    val toplevel = SpinalVerilog(AvalonMMUartCtrl(UartCtrlMemoryMappedConfig(...))).toplevel

    // Add some tags to the avalon bus to specify it's clock domain (information used by QSysify)
    toplevel.io.bus addTag(ClockDomainTag(toplevel.clockDomain))

    // Generate the QSys IP (tcl script)
    QSysify(toplevel)
  }
}

tags

Because QSys require some information that are not specified in the SpinalHDL hardware specification, some tags should be added to interface:

AvalonMM / APB3

io.bus addTag(ClockDomainTag(busClockDomain))

Interrupt input

io.interrupt addTag(InterruptReceiverTag(relatedMemoryInterfacei, interruptClockDomain))

Reset output

io.resetOutput addTag(ResetEmitterTag(resetOutputClockDomain))

Adding new interface support

Basically, the QSysify tool can be setup with a list of interface emitter (as you can see here)

You can create your own emitter by creating a new class extending QSysifyInterfaceEmiter
