1.7.8.2. Software Parameters

The software parameters defined in the main header file, main.h, controls various behaviors of the C code.

Table 47.  Software Parameters
Parameter Default Value Description
DEBUG_MODE 0 Set to 1 to print debug messages, else set to 0.
PRINT_INTERRUPT_MESSAGES 1 Set to 1 to print JESD204B error interrupt messages, else set to 0.
PATCHK_EN 1 Set to 1 when test pattern checker is included in the initial design data path configuration, else set to 0.
DATAPATH 3

Set to indicate the JESD204B IP configuration:

1 – TX data path only.

2 – RX data path only.

3 – Duplex data path (TX and RX data path).

MAX_LINKS 1

Set to indicate the number of links in the design (for example, for dual link, set MAX_LINKS=2). See Implementing a Multi-Link Design section for more detailed instructions on implementing multi-link use case.

Note: When using the design as-is, the maximum value of MAX_LINKS is 16. To increase the limit, redesign the address map in Qsys.
LOOPBACK_INIT 1 Initial value of the loopback. Set to 1 for internal serial loopback mode, else set to 0.
SOURCEDEST_INIT PRBS

Initial value of source/destination. Set to indicate test pattern generator or checker type or user mode:

USER – User mode (no test pattern generator or checker in data path).

ALT – Test pattern generator or checker set in alternate checkerboard mode.

RAMP – Test pattern generator or checker set in ramp wave mode.

PRBS – Test pattern generator or checker set in parallel PRBS mode.
