Chapter 11: Deterministic Latency PHY IP Core 11–13
Interfaces
November 2012 Altera Corporation Altera Transceiver PHY IP Core
User Guide
Interfaces
Figure 11–4 illustrates the top-level signals of the Deterministic Latency PHY IP Core.
The variables in Figure 11–4 represent the following parameters:
<n>—The number of lanes
<w>—The width of the FPGA fabric to transceiver interface per lane
<s>— The symbol size
<p>—The number of PLLs
1 The block diagram shown in the MegaWizard Plug-In Manager 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 _hw.tcl file that describes the component. If you turn
on Show signals, the block diagram displays all top-level signal names.
f For more information about _hw.tcl files, refer to the Component Interface Tcl Reference
chapter in volume 1 of the Quartus II Handbook.
