Interfaces
The Native PHY includes several interfaces that are common to all parameterizations.
It also has separate interfaces for the Standard and 10G PCS datapaths. If you use
dynamic reconfiguration to change between the Standard and 10G PCS datapaths,
your top-level HDL file includes the port for both the Standard and 10G PCS
datapaths. In addition, the Native PHY allows you to enable ports, even for disabled
blocks to facilitate dynamic reconfiguration.
1 Because this Native PHY allows you to dynamically reconfigure between
The Native PHY uses the following prefixes for port names:
■ Standard PCS ports—
tx_std_
,
rx_std_
■ 10G PCS ports—
tx_10g_
,
rx_10g_
■ PMA ports—
tx_pma_
,
rx_pma_
Enable tx_10g_bitslip port On/Of
When you turn this option On, the 10G PCS includes the
tx_10g_bitslip
input port. The data slips 1 bit for every
positive edge of the
tx_10g_bitslip
input. The maximum shift
is <pcswidth>-1 bits, so that if the PCS is 64 bits wide, you can
shift 0–63 bits.
Enable rx_10g_bitslip port On/Off
When you turn this option On, the 10G PCS includes the
rx_10g_bitslip
input port. The data slips 1 bit for every
positive edge of the
rx_10g_bitslip
input. he maximum shift is
<pcswidth>-1 bits, so that if the PCS is 64 bits wide, you can shift
0–63 bits.
