This paper presents the optimistic synchronization mechanism predictive time warp (PTW) based on the implementation time warp of the virtual time paradigm for use in the simulation of electronic systems and high level system simulation. In comparison to most existing approaches extending and improving classical time warp, the aim of this development was to reduce the roll-back frequency of optimistic logical processes without imposing waiting periods. Part of PTW is the introduction of forecast events predicting a certain period in the future and thus reducing the roll-back probability. On the example of a distributed logic simulation the benefit of the PTW synchronization approach is shown
