CHAPTER2 Dependence Functions
■RAM Checker Viewer
The RAM Checker Viewer is a tool to graphically display the data value that changes as time
goes by. It displays data value in the following three formats:
- Bit display (image of Logic Analyzer)
- Data value display (line graph)
- Bit/data value display (simultaneous display of bit and data value)
Other display information includes CPU stop, trigger point, and data lost.
Regarding CPU stop, the STOP mode in a low power consumption mode and the power-off state while
using the power-on debug function are recorded in the log.
Trigger point uses event hit of the SOFTUNE Workbench. To use the trigger point, set events in the
SOFTUNE Workbench. When an event hits, its information is recorded in the log.
Data is lost due to the following two types of factors:
●Hardware
The emulator usually gets the RAM data access history at 1ms intervals. If data access
occurs to the same address twice or more within 1ms, the emulator gets only the data accessed last. Data
lost due to hardware indicates that data access is performed multiple times.
●Software
The SOFTUNE Workbench usually gets data from the emulator at 100ms intervals. However, it may not
get data due to the effect of other applications, etc. at 100ms intervals. In this case, although data cannot be
displayed partially, the disabled time slot is displayed graphically.
Note:
When logging stops due to break or execution stop, data lost due to software may be displayed for
1ms to 15ms at the end of the log. This occurs because the log after program execution stops is
obtained until logging stops, and so it is not an actual data lost. For details on the RAM Checker
Viewer, refer to "RAM Checker Viewer Manual" (FswbRView.pdf) or online help information.
