Bernhard,

We have some experience with simulation of BURST interfaces using tools of
INCASES' EMC-WORKBENCH.

We used a special model of a coupling clamp which depends on the real test
environment (coupling clamp, transmission lines resp. cables). We also have
implemented a special model of a BURST generator.

Looking at the according standard, you will find a definition of the waveshape
of a single pulse and a graph of a burst. The repetition period is in the order
of 0.2 to 0.4 ms, the BURST duration is 15ms, and a BURST period of 300 ms.
In general, the line length on typical PCB applications, the rise and fall times
of the components,etc. lead to simulation time steps in the order of ns.
Therefore, the simulation can be time and memory consuming.

Additionally, the models of the components are often not valid for the voltage
level during a BURST test, so that special models have to be used. Nevertheless
we got some really good first results for a BURST simulation.
