On improving efficiency of model checking through systematically ...

own specification language. However, an XML schema for PMC model was
already defined and a tool to translate the model in XML format to PMC
input language is available.
Figure 3.4 presents the Uppaal XML representation of the model given in
Figure 3.3.
int x,y;bool b;
P
s0
y >0
s1
x > 0
y := x+1,b:=true
system P;
Figure 3.4: XML representation of the Uppaal model created from Figure 3.3.
Consider Figure 3.4. Variable declarations are specified in tag declaration.
Each automaton in Uppaal is called a template and thus saved in tag
template. Locations and transitions are specified together with invariants,
guards, assignments in appropriate tags. Note that invariants, guards and
assignments are stored as strings.
The XML representation of PMC model is similar to Uppaal. Components
such as variable declarations, Boolean expressions and assignments are specified
in a different way. For instance, in Uppaal, to model the assignment
y:=x+1, we just put the whole string in the label associated with the transition.
On the contrary, in PMC, that assignment is split into atomic elements
as follows:
y
x
