What is the meaning of :*= and :=* operators?

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

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

  • These are not Chisel operators. Instead, they're defined and used by Rocket Chip's diplomacy package. These are shorthand operators for doing different types of binding between diplomatic nodes.

    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.
