Host Seconds shows the number of user and system seconds of host CPU time the simulator has uses since it started.
Sim Seconds is the number of seconds of simulated time that has past since the simulator started.
MIPS are the total number of simulated instructions executed since the simulator started, divided by the Hosts Seconds.

The simulation counter measures the number of microseconds of simulated time. However, it is not a performance or
3.4.2 CPU-Statistics Graphs
There are several graphs that can be displayed on the left side of the Main Window. These graphs can be activated by the “View→CPU Graphs” menu selection.
3.4.2.1 Translation Graph
The Translation Graph updates once a second. Full vertical scale means the address- Translation cache (tcache) is full. Dark color on the bottom of the graph represents percent of tcache containing valid translations. Lighter color above the dark color represents percent of tcache containing invalidated translations. Black color growing from the top represents the meta data that describes the translations.
Percent of tcache containing Invalidated Translations.
Meta Data that describes the Translations.
Percent of tcache containing Valid Translations.

3.4.2.2 Real MIPS Graph
The Real MIPS Graph updates once a second. If this value exceeds what can be displayed on this graph, the graph line turns red. It shows the instantaneous MIPS, i.e., how many millions of instructions per host
