A simulator interface unit receives simulation results associated with a particular set of result identifiers and generated by an electronic design simulator. For each such result identifier, a history file manager stores a simulation result corresponding to a simulation-time value change. The history file manager additionally stores each simulation result generated beyond a first result activity during the execution of simulation code associated with each simulation-time value. The history file manager maintains an internal-time value that indicates when each stored simulation result was generated during the execution of simulation code, relative to the generation of each other stored simulation result. The history file manager generates a time translation table that associates unique simulation-time values with internal-time values. A results data server, in conjunction with viewing and interface tools, selectively present simulation results in a simulation-time format or a sequence-time format. In the simulation-time format, final simulation results generated at each simulation-time value are shown, and a set of simulation-time markers is shown. Each simulation-time marker indicates whether multiple assignments were made to a given variable during the execution of simulation code associated with a particular simulation-time value. In the sequence-time format, initial simulation results generated for a given simulation-time value as well as each variable change that occurred during the execution of simulation code associated with this simulation-time value are shown.
