5. Signals

This chapter describes the Interlaken MegaCore function signals.

1 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.
