3.2.13. Statistics Counters Interface

The statistics counters modules are synthesis options that you select in the LL 100GbE parameter editor. However, the statistics status bit output vectors are provided whether you select the statistics counters module option or not.

The increment vectors are brought to the top level as output ports. The increment vectors also function internally as input ports to the control and status registers (CSR).

Table 22.  Statistics Counters Increment Vectors The TX statistics counter increment vectors are clocked by the clk_txmac clock, and the RX statistics counter increment vectors are clocked by the clk_rxmac clock.
