Parameter Table Example

Figure 17: Parameter Table Example

This figure shows an example of a design containing two Altera PHYLite interfaces, each with one

bidirectional group composed of 4 data bits and one strobe. Both interfaces are in the same I/O

column and therefore their tables must be merged.

strobe_io = lane 0x00, pin 0

data_io[3] = lane 0x3A, pin 8

Note: Note there is no guarantee of the ordering of the interface parameter tables in the

merged table, so a specific interface will have to be searched for.

Example Design Avalon Controller

An addressing operation can be complicated and error prone. Accidentally addressing the wrong interface

of the IP cores may result in debugging runtime errors difficulties. Therefore, the example design provides

an Avalon controller to simplify the dynamic control of an interface. Altera recommends you to simply

integrate the provided example controller into a dynamic reconfiguration design.
