Some customers only need to understand one critical block — the protection circuit in a power IC, or the sampling front end of an ADC. Analysing the full die would be wasted effort.
Others need only high-resolution layer-by-layer die imagery, or device identification and net annotation without full schematic recovery. Both are available on their own.
Marking the region directly on the top-layer photograph from the evaluation report is the clearest way to communicate scope — we quote against exactly what you circle.
Memory arrays and auto-placed-and-routed (APR) digital blocks are outside the scope of analysis. And on a partial scope, nets crossing the boundary are not traced beyond it — the schematic shows signals entering and leaving, but where they go outside the region is not part of that engagement. If a signal’s source or destination matters to you, include it in the region you outline.
