9. Timer functions

This group of functions covers VSE capability to work with timers -an internal routines that

repeatedly measures a timing intervals between different events.

9.1 VSE time object

A VSE time object – is a special object that presents time intervals in verification scripts.

From point of view of CSL - the verification script time object is a “list”-object of two elements :

( Please see CSL Manual for more details about CSL types )

[seconds, nanoseconds]

NOTE: The best way to construct VSE time object is to use Time() function (see

below )

9.2 SetTimer()

Starts timing calculation from the event where this function was called.

Format : SendTimer( timer_id =0)

Parameters:

timer_id – a unique timer identifier.

Example:

SetTimer(); # - start timing for timer with id = 0;

SetTimer(23); # - start timing for timer with id = 23;

Remark :

If this function is called second time for the same timer id – it resets timer and starts timing

calculation again from the point where it was called.

9.3 KillTimer()

Stops timing calculation for a specific timer and frees related resources.

Format : KillTimer( timer_id =0)

Parameters:

1 2 ... 14 15 16 17 18 19 20 21 22 23 24 ... 34 35
