I see some examples in the RocketChip, but could not find info in the API reference



  masterNode :=* tlOtherMastersNode
DisableMonitors { implicit p => tlSlaveXbar.node :*= slaveNode }

          No published API documentation for this exists, but you can start poking around in the diplomacy package. The releveant location where these are defined is src/main/scala/diplomacy/Nodes.scala.

            Yeah, Diplomacy, while being a great differentiator of Chisel, is a highly esoteric feature with a poor documentation. We need to add more info about that and publish simple examples beyond Rocket

          • Note, that while esoteric, it solves a very real problem: I want to hook up N things together and I want their parameters to be a function of what I'm hooking up. Before, this would require very complicated configuration files. Diplomacy makes that far easier, albeit with some complicated software engineering on top of Chisel to enable pre-elaboration actions. If you haven't taken a look at the Diplomacy paper from CARRV 2017, it's a great reference: carrv.github.io/2017/papers/cook-diplomacy-carrv2017.pdf.
