# Introduction
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. This new tab allows you to inspect the internal details of CDMA/OFDMA cluster based on data on one event.
After a simulation these GUI parts are used to provide access to calculated results but also detailed insight into the last event of the simulation as illustrated in Figure 265, but you can reproduce any event using the play/replay feature (Section 2.15).
The “Summary of event #n” and “inspect selected element” panel of Figure 265 are shared components from the CDMA and OFDMA module.
