LogiCORE Tri-Mode Ethernet MAC Core - The core times out with the hardware evaluation license before the advertised 6-8 hours


General Description:

When using the LogiCORE Tri-mode Ethernet MAC Core with the hardware evaluation license, the core times out and stops functioning much sooner than the 6 to 8 hours that it is supposed to take.


The reason for this problem is that the evaluation logic relies on the MAC Speed Configuration setting to match the actual operating speed of the core. Therefore, be sure to set the MAC Speed Configuration Word either through the Host Interface (if using the management interface) or through the Configuration Vector (if not using the management interface) to match the running core speed. This should be done initially, as well as any time the speed of the core changes.
