Activation Inheritance in Modelica
Ramina Nikoukhah · 2008
Modelica specifies two types of equations: the equations defined directly in the "equation " section, which are supposed to hold all the time, and the equations defined within a "when " statement. The latter are "activated " by explicit events at corresponding times. In making the analogy with Scicos, the equations of the first type are the counterpart of "always active " blocks whereas the second type equations are "event activated " blocks. A useful feature in Scicos is the mechanism of activation inheritance. In this paper, we examine the possible extension of the Modelica specification to introduce a similar mechanism in Modelica.
