5.12 Measuring Data Coverage
5.12.1 Measuring Data Coverage
The E100 emulator has its code coverage, data coverage and realtime profile functions usable exclusively to each other.
To use the data coverage function, choose Data Coverage in the Exclusive Functions section on the System page of the
Configuration Properties dialog box.
Data coverage is the function to indicate “what kinds of accesses have been made” to the data area.
This function collects access information every byte without causing a program to break. Therefore, the realtime capability of
the user program will not be lost.
The coverage result is updated upon a break.
The E100 emulator comes with 512 Kbytes of data coverage memory.
With initial settings, the data coverage memory is allocated automatically to addresses in the ROM and RAM areas in this
order.
5.12.2 Opening the Data Coverage Window
Choose Code -> Data Coverage from the View menu or click the Data Coverage toolbar button [ ].
The Data Coverage window initially appears in a blank state.
