Chapter 14: 10/100 Ethernet Physical Layer Interface
R
The hardware evaluation versions of the Ethernet MAC cores operate for approximately
eight hours in silicon before timing out. To order the full version of the core, visit the Xilinx

UCF Location Constraints
Figure 14-4 provides the UCF constraints for the 10/100 Ethernet PHY interface, including
the I/O pin assignment and the I/O standard used.
