Running a simulation
Once the simulation scenario has been completely defined (in other words, once you have defined the victim link and at least one interfering link) and the simulation control parameters were checked, you may proceed with performing the actual simulation, i.e. the generation of simulated scenario events.
The simulation is started when you click on the Start button of SEAMCAT toolbar. The simulation starts and all other commands/buttons are meanwhile disabled, except the Stop button:
Before the event generation starts, SEAMCAT will automatically perform the consistency check of the scenario parameters. See separate section for interpretation of error or warning messages.
The simulation will run until the termination criteria set in simulation control had been fulfilled, i.e. either the prescribed number of trials had been performed or the time limit had been reached. Besides, you can stop the simulation at any time (after completion of a given snapshot) by pressing the Stop button.
The progress bar on the top left corner of the screen reflects the proportion of carried out events with respect to overall number of scheduled events.

During the event generation all involved transceivers (ILT, ILR, VLR and VLT) are plotted in graphical display window placed on the simulation outline tab page.
When simulating CDMA or OFDMA systems, you will have access to the additional tab "Cellular structure", which will become active after completion of the simulation, allowing you to inspect the internal details of CDMA/OFDMA cluster based on data from the last event.
After performing event generation you are then able to:
| examine event generation results | perform interference calculation | generate a report of the simulation |
