Nios Trace Format

is there a documentation for the Nios trace format? The handbook says it's in a compressed format, I'd like to know the format if it's not super secret information.

Aha! Which file is the java monitor program?

Mainly, I am hoping to get the trace from the off-chip pins (offchip_trace_clk, offchip_trace_data and trigout). From a look at SignalTap there doesn't seem to be much happening, which makes me think that perhaps the trace output needs to be 'enabled' (through the JTAG?) hence the trigout pin telling the logic to start recording.

If this is the case there are two issues I need to overcome:

- how to enable the trace output

- how to convert this output into address accesses

Any help on either of those would be much appreciated!
