My research is mainly focused on generating test sequences automatically using Colored Petri net.CFG provides techniques for generating test sequences. But some papers says that, test sequence generation methods based on a control flow graph sometimes suffers from a feasibility problem (i.e. some paths in a CFG may not be feasible).So I need a technique to draw a Control flow graph from the Colored Petri net model, in a way that, when I will select paths from the control-flow graph it will contain only the feasible paths.Then I will generate test sequences from the CFG. Can anyone help me finding any technique please or give me any suggession??
Since you are interested in generating test sequences automatically using colored Petri nets, note that it's not clear that you need reduction to control flow graphs (and dealing with all the related issues). Some techniques were presented, that use various different methods to generate test sequences from Petri nets. Some examples include:
H. Watanabe and T. Kudoh, "Test suite generation methods for concurrent systems based on coloured Petri nets," Software Engineering Conference, 1995. Proceedings., 1995 Asia Pacific, Brisbane, Qld., 1995, pp. 242-251.

On the other hand, since Petri nets and control flow graphs are not semantically equivalent in general (and capture different type of information), the translation between the two is usually done in some specific domain (and restrictions). (Although usually, control flow graphs can be transformed into equivalent Petri nets.). Some examples and discussions are given in:
Note that your question seems a bit too general. (Moreover, it also seems as an instance of XY, as noted by D.W.) Without more details, it seems hard to give a concrete and concise answer. Hopefully, given pointers can get you closer to your desired goal.
