Statistics Resource Type |
This option indicates the type of implementation of the statistics counters. Note: This feature is enabled when Include AXI4-Lite Control and Statistics Interface and Include Statistics Counters are selected. |
Registers |
Registers Block RAM (4) |
Notes: 1. Requires TX to be enabled. Operation = Simplex TX or Duplex modes only. 2. Requires RX to be enabled. Operation = Simplex RX or Duplex modes only. 3. Option is disabled when receive flow control is disabled. 4. Block RAM usage for the Statistics counters will be supported in a future release. |
