Detailed Description

monitors all 5 channels for activity

Sends Write Address, Write Response and Read Address out on each clock
Sends entire Write Data and Read Data out together
Driver
* Updates agent memory on each write data beat
Responder
* Sends a read data sequence to the responder when a read address transaction is detected Main cover properties and assertions are here.
