It depends on which temperature (K or C) you set as the ambient in the .config file. Each entry in .ttrace corresponds to block temperatures at the end of each sampling interval, which is also set in .config. For example, the default sampling interval is 3.33us, ie. 10K cycles for a 3GHz clock. Hope this is helpful. -Wei
