I noticed that occupyBus() sets pkt->firstWordTime and pkt->finishTime.
However, these variables are only utilized
by Cache::handleResponse(). What if the packet is a request? I'm just wondering
how firstWordTime and finishTime is handled in all cases.
Thanks!

Subject: [m5-users] bus latency modeling
I have a question regarding Bus::recvTiming
In this function, occupyBus() calculates when the packet is received
completely by dest_port (tickNextIdle). However, "sendTiming" is executed
instantly afterwards without delay (both to dest_port and snoop ports). I
understand the "adding instead of dividing" trick, but for this latency model
to be effective, shouldn't the dest_port and snoop ports see the packet at
tickNextIdle? Am I missing something?
Thanks!
