The proposed upgrade to the D0 detector's data acquisition system
and
high level trigger has been simulated using the commercial
programming
language, MODSIM. This paper contains a brief description of the
simulated data acquisition system. The simulation program is
described
in detail, including its object oriented design and other features
which make it simple to simulate a range of configurations. Results
from the simulation feedback into the hardware design. The
simulation
is sufficiently detailed so that we can examine failure modes and
realtime recovery algorithms. Results are shown for various likely
senarios (event size, trigger rate, etc.). The data acquisition
system is highly
scaleable. The minimal version was shown to work well at a rate of
1300 Hz with 250 KByte events. The simulation is a continuing
project;
as the design is refined, the simulation is changed to match and as
hardware appears, the simulation is updated. We report on the
status
of the project and the utility of these simulations.
