Title: APNNed - a Net Editor and Debugger within the APNN Toolbox Authors: Peter Buchholz, Peter Kemper, Faisal Amir, Fatih Bosdag, Boris Goz, Stefan Illner, Marc Kaiser, Dimitri Knjazew, Selim Narci, Liliane C.~Nouthe Sandjon, Dirk Pessarra, and Carsten Tepper Abstract: The paper presents APNNed, a new component within the APNN toolbox, that allows editing, visualization and debugging of certain colored Petri nets, which can result from a translation process of other Petri net tools. APNNed supports refinement of places and transitions to achieve hierarchical nets. Its facilities to perform the token game include consideration of break points as a feature well known from debugging software. APNNed is the result of a students project, such that authorship is clearly shared with the 10 members of this group. Keywords: Colored Petri nets, Hierarchical Petri nets, net editor
