The MESH Simulator

MESH [Pau02b] is a heterogeneous systems simulator that bridges logical and

physical time. An event is a pair of a tag and a value. The tag denotes time; but

time may not necessarily be wall clock time. The behavior of a thread is given

by an ordered set of events. Depending on the level of detail at which the system

is modeled, the events may be mapped onto physical time or onto logical

sequences. In simple cases, a simulation of the logical simulation can be trans-

formed into a simulation in physical time simply by adding time steps in the log-

ical sequence. However, in many cases, ...
