TracerV TriggerSource/TriggerSink annotation not working

[bgottschall]

I created a new tracing interface which allows me to pipe out additional informations out of the simulation. I've created this interface exactly like TracerV, but a little bit simpler as it is just tracing out a bit vector. The interface works exactly as expected and I retrieve so far in the Verilator simulation exactly the data from my Bridge that I want. Now I wanted to reuse the TracerV trigger to enable tracing between certain trigger points. The documentation talks about the TriggerSource and TriggerSink annotation and the trigger is annotated as far as I can see like that in the TracerV Bridge.

So I tried to do the following:

object GenericTraceBridge {
  def apply(generic_trace: TileGenericTraceIO)(implicit p:Parameters): GenericTraceBridge = {
    val ep = Module(new GenericTraceBridge(generic_trace.bitWidth))
    withClockAndReset(generic_trace.clock, generic_trace.reset) { TriggerSink(ep.io.tracevTrigger, noSourceDefault = false.B) }
    ep.io.trace := generic_trace
    ep
  }
}

However it gives me during the FIRRTL transformation the following error:

Thanks Bjorn, i'm looking into it.

@bgottschall, i'm sorry i never got around to fixing this.

The links are dead now -- did you workaround the problem?

[bgottschall]

For my purpose I did work around this problem by just not using any triggers and tracing every cycle. I just linked my target application into a address range that was unique so I could identify the data of interest.

But it would be great to attach to the tracerV trigger to selectively trace. I give you new links, my university decided to put this server behind a firewall ;) https://bgottschall.de/smallboom.fir.xz https://bgottschall.de/anno.json.xz
