Introduction
This project started as a tool for real-time
visualization of data coming from the Tiny-Tera simulator, a
system-level, event-driven simulation of the tiny-tera switch. Later it was generalized so as to make it easy to integrate
with other simulators, so that the researchers working on simulations can benefit from it.
The objectives of the project were twofold:
- Help the developers debug their code by being able to see what
is going in the simulator, and to look for anormalities in the
behaviour of the simulator.
- Help the researchers to observe the progress of the simulation in
real-time.
The graphing tool can be attached to the simulator at any time. It starts
by extracting from the simulator the information about what variables can be
displayed, making it fairly independent from the simulator itself. Then
the user choses to display one of them. Two views are currently available:
a bar-graph and a time-series graph. In the bar-graph mode some statistics
can be displayed with the variable, if they are available. The user can also add more variables
to the current graph, so that they can be directly compared to other variables. He/she can also create new graphs. These variables can
be removed later. There is limited suppor for zooming and scrolling the
graphs.
Here are some screenshots:

User's Manual
This is too long to be placed here, so please, follow this link
Developer's Guide
This is again too long. You can find it here link
The applet
You will need JDK 1.1.5 or greater and the Swing classes or JDK 1.2 to run
the following application. For more information on how to install these please go to the web site
of your web browser vendor or to Javasoft's home page.
IMPORTANT: In order to see this applet running you need to launch first the
simulation on the same machine from which you downloaded this page
from. Launching the different applet windows may take long (sometimes as
long as 1 min, I know, Java is
not the fastest language I've ever seen). Please be patient.
For those with an account on klamath.stanford.edu, you can get the
latest copy doing a "cvs checkout ttgraph", then make it, a run it as
"ttsim config.ds8".
If you still want to play around with the graphing tool, but without
interacting with the simulator, you can go here.
