Formát dát na definovanie Simulátoru (SimComponent)
Definovať spustiteľný simulátor je možné pomocou SimCompoment-u ako komponentového stromu. Je to zloženie základných komponent, ktorých vstupy a výstupy sú navzájom prepojené. Základná komponenta (list stromu) môže byť dvoch druhov.
- ovládač prostredia (spúšťa sa samostatne). Name==Environment & no children
- komponenta v danom prostredí (môže sa spúšťať automaticky cez ovládač daného prostredia). Name!=Environment & no children
Je dobré si uvedomiť, že pri práci s definíciami komponent a ich prepojení sa nepracuje s hodnotami premenných(resp. udalostí). Hodnotu premennej(resp. udalosti) za behu aplikácie je lepšie držať pevne v rukách komponenty, ktorá danú hodnotu vytvorila(v prípade udalostí je to komponenta, ktorá dané udalosti spracováva). Ukazuje sa, že nie je nutné ani vhodné aby túto hodnotu menili iné komponenty. Inštancia základnej komponenty tak definuje v SimKernel-e každú jej výstupnú premennú(resp. poslucháča udalostí) avšak nedefinuje v SimKernel-e žiadne vstupné premenné (resp. samotnú hodnotu udalosti). Prepojenie výstupných premenných na vstupné zabezpečujú atribúty „inputRef“ a „outputRef“. Hodnotou atribútu je lokálny názov vstupu spolu so skupinovým názvom výstupu. Prepojenie udalostí(outputEvent) na poslucháčov udalostí(inputEvents) zabezpečujú atribúty „inputEventsRefs“ a „outputEventsRefs“. Hodnotou atribútu je lokálny názov udalosti spolu so skupinovým názvom poslucháča. Premenné skupiny je z pohľadu z vnútra skupiny nutné chápať obrátene, tak aby platilo: vonkajší výstup zo skupiny je výstupom z jej potomka(output), vonkajší vstup do skupiny je napojený na vstupy potomkov(inputs), vonkajší poslucháč skupiny je poslucháčom potomoka(inputEvents), vonkajšia udalosť skupiny je napojená na udalosti potomkov(outputEvents).
Prvá implementácia podporných premenných v surovom formáte na SimKernel-u
Na jednom SimKernel-u môže v jeden moment bežať viacero inštancií viacerých aplikácií. V tomto režime, keď SimKernel beží nonstop ako služba je nutné riešiť réžie s rôznymi časťami =komponentmi rôznych aplikácií.

Prvým komponentom je vždy SimSystem, ktorý umožní definovanie ďalších komponent, spúšťanie ich inštancií a registrovanie spustenej inštancie ako ovládač pre konkrétne prostredie (SimEnvironmentDriver). Každé prostredie, ktoré bude chcieť plne podporovať služby SimKernel-u bude implementovať rozhranie SimEnvironmentDriver, ktoré bude podporovať spúšťanie inštancií komponentu daného prostredia podľa jeho definície sprostredkovane cez inštanciu SimSystem.
Komponentové stromy, ktorých všetky komponenty sú v zaregistrovaných prostrediach, je možné spúšťať jednotným príkazom (START:SimSystem:inputEvent), ktorý vyžaduje na vstup názov definície komponenty (compDefName:SimSystem:input, prípadne localName:SimSystem:input alebo globalName:SimSystem:input) a na výstup poskytuje číslo inštancie komponentu (compID:SimSystem:output). Po vytvorení komponent je ich možné spájať (RECONNECT:SimComponent:inputEvent), keď sú známe všetky zdielané premenné (sharedIDs:SimComponent:input) a všetky identifikátory súrodeneckých komponent (siblingIDs:SimComponent:input, a prípadne aj siblingIdx:SimComponent:input v prípade, keď sa znova prepája len jedna komponenta).
