RTOS Analysis
Highlights – Statistic evaluation and graphic display of task
run times – Task related evaluation of function run times – Statistic evaluation and graphic display of task
states – Manual executed system calls – Task stack coverage – PRACTICE functions for OS data – RTOS related pull-down menu – Task selective debugging

Coverage Analysis
Controlled by software, the captured address ranges can be collected. – Display of captured addresse – Display of captured functions – Selection of Address Ranges
Copyright McCabe & Associates 1998
Performance Analysis
Function Timechart – View critical program paths – Documentation Duration – Execution time – Response time Distance – Time between samples Distribution – Interface analysis – Interrupt analysis – System state analysis – Statistical analysis

Performance Analysis
The statistic unit measures independently from the trace memory, the run time of specific modules of the program. Using this, the average execution time, the average execution frequency and the absolute number of calls to the entry point of a routine can be measured. Up to 63 routines can be monitored in this way
Modules Functions Address ranges Automatic Modes Scanning Modes

Coverage Analysis
Coverage Trendency with time Display the excuted code and non excuted code the ratio of fuction or module coverage the covrage display by histogram and statistics diagram
