Functional Description¶

General¶

These Functionblock is used for the generation of signals after each cpu-restart. the cpu-restart can be triggerd by the simulation input xTest (= TRUE)
independently of an actual CPU restart.

The output xQ1 changes permanently from FALSE to TRUE after each CPU restart with a time delay of TimeQ1.
At impulse output 1 xQ1p, a single impulse with the pulse length TimeQ1Pulse is generated during this status change.

The output xQ2 changes permanently from FALSE to TRUE after each CPU restart with a time delay of TimeQ2.
At impulse output 2 xQ2p, a single impulse with the pulse length TimeQ2Pulse is generated during this status change.
