3.4.1.5. TX Statistics Registers
The TX statistics registers count TX Ethernet traffic and errors. The 64-bit statistics registers are designed to roll over, to ensure timing closure on the FPGA. However, these registers should never roll over if the link is functioning properly. The statistics registers check the size of frames, which includes the following fields:
- Size of the destination address
- Size of the source address
- Size of the data
- Four bytes of CRC
The TX statistics counters module is a synthesis option. The statistics registers are counters that are implemented inside the CSR. When you turn on the Enable TX statistics parameter in the LL 100GbE parameter editor, the counters are implemented in the CSR. When you turn off the Enable TX statistics parameter in the LL 100GbE parameter editor, the counters are not implemented in the CSR, and read access to the counters returns read data equal to 0.
Reading the value of a statistics register does not affect its value. A configuration register at offset 0x845 allows you to clear all of the TX statistics counters.
To ensure that the counters you read are consistent, you should issue a shadow request to create a snapshot of all of the TX statistics registers, by setting bit [2] of the configuration register at offset 0x845. Until you reset this bit, the counters continue to increment but the readable values remain constant.
