  2. Points concernant le langage clause init clause extern opérateurs attributs (visibilité, orientation, …) synchronisations priorités Extensions XML Graphique Vers une norme Modulaire

  3. clause init init-cls ::=init (init-def ;)+ init-def ::= hierarchy-path := expression Redéfinition dans la hiérarchie Clause init

  4. extern-decl::=IDENTIFIER extern-term = extern-term::=IDENTIFIER extern-term extern-term::= constante::=STRING::=IDENTIFIER( extern-term (, extern-term)* )::={ extern-term (, extern-term)* }::=<flow hierarchy-path >::=<state hierarchy-path >::=<event hierarchy-path >::=<sub hierarchy-path >::=<local hierarchy-path >::=<term( expression )> Clause extern

  5. node component extern law <event a> = exponential(<local lbd>) ; unobservable {<event a>, <event b>} ; property good = <term (output >= 12)> ; edon node main sub c:component; edon law <event C.a> = exponential(<local C.lbd>) ; unobservable <event C.a> = true ; unobservable <event C.b> = true ; property good = <term (C.output >= 12)> ; Clause extern

  6. Loi de probabilité law {<event a>, <event b>} = exponential(0.001); constant(probability) exponential(lambda) GLM(gamma, lambda, mu) Weibull(alpha, beta, t0) periodic-test(lambda, period, t0) Dirac(delay) Paramètres nommés parameter lambda= 0.001; parameter <local A.B.lambda> = uniform(0.1,0.2); constante uniform(min-value, max-value) normal(mean, standard-deviation) lognormal(mean, error-factor) Clause extern

  7. Clause extern • Prédicats, propriétés, observateurs predicate production52 = <term (production=52)>; property prod = <term (A.production+B.production)>; observer mean_prod = weighted_value(<term production>); • Verrous • locker <term (C.failed)>

  8. Syntaxe :IDENTIFIER (,IDENTIFIER)* Utilisation Visibilité des flux, state, event public, parent, private affecte la mise à plat Orientation des flux (in, out) Attributs

  9. Identificateurs ajouter le ^ (mise à plat) Opérateurs arithmétiques min, max Switch Appels à des routines externes %nom-de-fonction Opérateurs

  10. Synchronisations “à la Mec” Diffusion Synchronisations relationnelles <Start: M.start and (S1.start or S2.start)>; GM |- M.start -> sM := expM; GS1 |- S1.start -> sS1 := expS1; GS2 |- S2.start -> sS2 := expS2; GM and (G1 or G2) |- Start -> SM := expM, sS1 := if (GS1) then expS1 else sS1, sS2 := if (GS2) then expS2 else sS2; DCC Synchronisations

  11. Priorités • Ordres partiels • Entiers
