Several attributes are used by power estimation tools. These power-only attributes are set by the DCMAC Subsystem IP Wizard based on parameters that you choose. These power-only attributes are not controlled through the AXI4-Lite interface. Furthermore, these attributes have no impact on the functional behavior of the DCMAC Subsystem.

Table 1. Power-Only Attributes
Name Type Description
LANE_CONNECTIVITY String Reserved.
MAC_ACTIVITY_FACTOR Real User prediction of how active the MAC will be in their application. What percentage of clock cycles is data passing through the MAC (that is, MAC interface enabled).
NUM_100G_FEC_NOPCS_PORTS Integer Number of ports running at 100 Gbps that include an operational FEC, but no operational PCS. When MAC and PCS are working independently, this is PHY (that is, FEC) only. When MAC and PHY are coupled together, this does not apply.
NUM_100G_PCS_NOFEC_PORTS Integer Number of ports running at 100 Gbps that include an operational PCS, but no operational FEC. When MAC and PCS are working independently, this is PHY (that is, PCS) only. When MAC and PHY are coupled together, this is MAC+PHY.
NUM_100G_PCS_WITH_FEC_PORTS Integer Number of ports running at 100 Gbps that include an operational PCS (or additional logic, like FlexO or 128GFC, beyond simply FEC-only Encode/Decode) and operational FEC. When MAC and PCS are working independently, this is PHY (PCS+FEC) only. When MAC and PHY are coupled together, this is MAC+PHY.
NUM_200G_PORTS Integer Number of ports running at 200 Gbps. When MAC and PCS are working independently, this is PHY (PCS/FEC) only. When MAC and PHY are coupled together, this is MAC+PHY.
NUM_400G_PORTS Integer Number of ports running at 400 Gbps. When MAC and PCS are working independently, this is PHY (PCS/FEC) only. When MAC and PHY are coupled together, this is MAC+PHY.
NUM_50G_FEC_NOPCS_PORTS Integer Number of ports running at 50 Gbps. When MAC and PCS are working independently, this is PHY (that is, FEC) only. When MAC and PHY are coupled together, this does not apply.
RXMAC_ACTIVE Integer Indicates that the receive MAC is active. Can only be set to 0 when the MAC and PCS are working independently.
TXMAC_ACTIVE Integer Indicates that the transmit MAC is active. Can only be set to 0 when the MAC and PCS are working independently.
