The following example shows an instruction trace with line numbers. We have delayed the trace by 200 microseconds to skip to the lines of interest.
$ leon-coff-run -t -d 250 hello

...lots of output...
In this second example we run the demo program then interrupt with Ctrl-C. Using the -z option we get a short report on tasking showing task switches and the lock levels in the current task.
$ leon-coff-run demo -z
...
Ctrl-C

Tasks, y-axis is task number
'>' Task running
'.' Task in ready queue
' ' Task blocked

Locks and active priority for current task (above), y-axis is priority
Note: blank rows omitted
'b' No locks, therefore base priority
