We have developed a versatile software package for the simulation of di-electron production in pp and dp collisions at SIS energies. Particular attention has been paid to incorporate different descriptions of the Dalitz decay \Delta \to N e+e- via a common interface. In addition, suitable parameterizations for the virtual bremsstrahlung process NN \to NN e+e- based on one-boson exchange models have been implemented. Such simulation tools with high flexibility of the framework are important for the interpretation of the di-electron data taken with the HADES spectrometer and the design of forthcoming experiments.
