Testing Embedded Systems in the Automotive Industry with TTCN-3

Example: Comparison of Message Timingin Standard TTCN-3www.temea.orgArrival of messages m o ,..,m n and thetimeout of timers t 0 ,..,t m are denotedby events e 0 ,..,e k+1 ,9timing is measured by comparisonof events, andonly events that occur in differentsnapshots are distinguishable.Duration between two consecutive snapshot denote the bestaccuracy of time measurement for standard TTCN-3. Theduration depends on:- the number of messages that arrive and the number of ports(queues) to check,- the duration of check, decode, match for individual messages wherethe duration of decode and match is directly dependent on thecontent and structure of the message under observation.
