Coincident particle detection is a powerful experimental technique, which substantially contributed to the progress in many fields of physics in the past. In the actual coincidence experiment and during data analysis, the distinction between so-called "true" and "random" coincidences is essential. In order to support real-time data interpretation, we have developed a simulation procedure for coincidence maps, which considers information about experimental parameters and boundaries. The simulation allows reproduction of the measurement results and can also deliver information on the relevance of random coincidences. This supports the experimental process as well as its preparation and the subsequent data analysis. We also demonstrate how the simulation may be utilized to apply novel coincidence schemes, e.g. with continuous excitation sources.
