Interfaces
December 2010 Altera Corporation Altera Transceiver PHY IP Core User Guide
Interfaces
Figure 3–3 illustrates the top-level signals of the 10Base-R PHY.
1 The block diagram shown in the GUI labels the external pins with the interface type
and places the interface name inside the box. The interface type and name are used in
the Hardware Component Description File (_hw.tcl).
f For more information about _hw.tcl files, refer to the Component Interface Tcl Reference
chapter in the SOPC Builder User Guide.
The following sections describe the signals in each interface.
