5.8.2 Recording Rules Page: How It Works
YoucanthinkoftheRecordingRulespageasaworkspaceforcreatingrecordingrules
(rulesthatdeterminehowtheanalyzerrecordstraces).Recordingrulesarecombinations
ofeventsandactions.
Aneventandtheactionoractionsassociatedwithitformarulestate.Oneormorestates
areencapsulatedinasequence.
Note:Therecanbefromoneto512stateswithinasequence.Youcanassociateoneormoreevents
witheachstate,andyouassigneacheventadifferentactionorthesameaction.
Asequencethathasonlyonestateiscalledasingle‐statesequence.Theanalyzer
continuouslywatchesforeacheventinthesequenceandexecutesthecorresponding
actioniftheeventisdetected.
Asequencethathasmultiplestatesisamulti‐statesequence.Thestatesarearrangedina
hierarchy,withatopstateandsuccessivelylowerstates.Onlyonestateinamulti‐state
sequenceisactiveatatime.Theanalyzerdoesnotgotoasuccessivestateunlessitis
directedtodosobythepreviousstate.
Sequencesaredescribedindetailin“UsingSequences”laterinthischapter.
Briefly,creatingaruleinvolvesthefollowingsteps:
1. CreatingEventbuttonsintheAvailableEventsarea.
2. Drag‐and‐dropofEventbuttonstotheappropriateareas(cells)intheMainDisplay
area.
3. AssigninganactionoractionstoeachEventbutton.
