Detailed Description
Declaration of the crossbar master port type, one will be instantiated for each of the slave ports connecting to the crossbar.

Member Function Documentation
◆ recvRangeChange()
|
inlineoverrideprotectedvirtual |
Called to receive an address range change from the peer slave port.
The default implementation ignores the change and does nothing. Override this function in a derived class if the owner needs to be aware of the address ranges, e.g. in an interconnect component like a bus.
Reimplemented from MasterPort.

◆ recvReqRetry()

inlineoverrideprotectedvirtual |
Called by the peer if sendTimingReq was called on this peer (causing recvTimingReq to be called on the peer) and was unsuccessful.
Implements TimingRequestProtocol.
