How long does the LogiCORE Gigabit Ethernet MAC or LogiCORE Tri-mode Ethernet MAC Core operate before timing out when using a Full System Hardware Evaluation license? What does a time-out look like?
Following configuration of the device, the Gigabit Ethernet MAC or Tri-mode Ethernet MAC Core will function correctly for approximately 8.5 hours. After this time, the core will cease to operate and block frames from passing through both the receiver and the transmitter. The only way to restore operation is to reconfigure the device; a simple core reset will not work.
When the core times out, all the buses will be inactive and all of the control signals on the receiver client side and transmitter GMII side interfaces will be held inactive.
