The
History
window does not display each thread on a separate line by default. It displays all
threads in a Microengine on the same line. To display the threads separately:
1. Right-click the Microengine whose threads you want to display.
2. Click
Expand Threads
for Microengine
n
,
where n is the Microengine you clicked on, or
double click on a Microengine name.
Note:
Only Microengines that have microcode loaded appear in the left-hand column.
To display all the threads in a Microengine on a single line:
1. Right-click on any of the thread in the Microengine.
2. Click
Collapse Threads for Microengine
n
, or double click on a Thread name.
Threads (and queues) appear on a timeline that represents the number
of cycles executed. A thread’s history is depicted by line segments
that change color depending on whether an instruction is executing
(black); aborted (yellow); stalled (red); its Microengine is idle (blue);
its Microengine is disabled (dotted blue).
You select which chip’s history is displayed using the box in the
upper left corner of the
History
window. Chip selection is
synchronized with chip selection in the
Thread Status
,
Queue Status
and
Memory Watch
windows.
