5. Signals
This chapter describes the Interlaken MegaCore function signals.

Qsys allows you to export signals with different names or prefixes. Refer to the Qsys
System Contents
tab for the signals that support this capability, and to the Qsys HDL
Example tab for the list of signals that are exported with predefined names. The
default prefix for a newly exported signal is the MegaCore function instance name in
the Qsys system. However, you can overwrite the name with which any signal is
exported. After you export a signal, it is added in the HDL Example tab with the
name you specify.
Interlaken Interface and External Transceiver Interface Signals
Table 5–1 through Table 5–3 list the pins related to the Interlaken interface of the
Interlaken MegaCore function. If you turn off Exclude transceivers, your Interlaken
MegaCore function includes high-speed transceivers.
Table 5–1 lists the Interlaken
interface data signals in that case.
If you turn on Exclude transceivers, your Interlaken MegaCore function does not
include high-speed transceivers. In that case, the data for the Interlaken link appears
on the external transceiver interface.
Table B–1 on page B–5 lists the external
transceiver interface signals.
Table 5–2 and Table 5–3 describe the Interlaken interface status signals. These signals
are available whether or not you turn on Exclude transceivers.
