The primary goal is to produce relevant contributions in the areas of expertise of the group and to disseminate them in renowned international journals and conferences. It is the group's aim that these contributions have a tangible and long-term impact on the scientific community. Technology transfer is considered a byproduct of research excellence and should be sought as a means of increasing the impact of the results, obtaining resources for the group and envisioning new directions for future research.

Recent Submissions

  • Petri net analysis using boolean manipulation 

    Pastor Llorens, Enric; Roig Mansilla, Oriol; Cortadella, Jordi; Badia Sala, Rosa Maria (Springer, 1994)
    Part of book or chapter of book
    Open Access
    This paper presents a novel analysis approach for bounded Petri nets. The net behavior is modeled by boolean functions, thus reducing reasoning about Petri nets to boolean calculation. The state explosion problem is managed ...
  • Genet: a tool for the synthesis and mining of Petri nets 

    Carmona Vargas, Josep; Cortadella, Jordi; Kishinevsky, Michael
    Conference report
    Open Access
    State-based representations of concurrent systems suffer from the well known state explosion problem. In contrast, Petri nets are good models for this type of systems both in terms of complexity of the analysis and in ...
  • Lazy transition systems: application to timing optimization of asynchronous circuits 

    Cortadella, Jordi; Kishinevsky, Michael; Kondratyev, Alex; Lavagno, Luciano; Taubin, Alexander; Yakovlev, Alex (Institute of Electrical and Electronics Engineers (IEEE), 1998)
    Conference report
    Open Access
    The paper introduces Lazy Transitions Systems (LzTSs). The notion of laziness explicitly distinguishes between the enabling and the firing of an event in a transition system. LzTSs can be effectively used to model the ...
  • Petrify: a tool for manipulating concurrent specifications and synthesis of asynchronous controllers 

    Cortadella, Jordi; Kishinevsky, Michael; Kondratyev, Alex; Lavagno, Luciano; Yakovlev, Alex (Universitat Politècnica de Catalunya (UPC), 1996)
    Conference report
    Open Access
    Petrifyis a tool for (1) manipulating concurrent specifications and (2) synthesis and optimization of asynchronous control circuits. Given a Petri Net (PN), a Signal Transition Graph (STG), or a Transition ...
  • Quasi-static scheduling of independent tasks for reactive systems 

    Cortadella, Jordi; Kondratyev, Alex; Lavagno, Luciano; Passerone, Claudio; Watanabe, Yosinori (Springer, 2002-06)
    Article
    Open Access
    The synthesis of a reactive system generates a set of concurrent tasks coordinated by an operating system. This paper presents a synthesis approach for reactive systems that aims at minimizing the overhead introduced by ...
  • Hardware and Petri nets: application to asynchronous circuit design 

    Cortadella, Jordi; Kishinevsky, Michael; Kondratyev, Alex; Lavagno, Luciano; Yakovlev, Alex (Springer, 2000-06)
    Article
    Open Access
    Asynchronous circuits is a discipline in which the theory of concurrency is applied to hardware design. This paper presents an overview of a design framework in which Petri nets are used as the main behavioral model for ...
  • Robustness to voltage noise with ring oscillator clocks 

    Machado, Lucas; Roca Pérez, Antoni; Cortadella, Jordi (2019-04)
    Article
    Open Access
    Voltage noise is the main source of dynamic variability in integrated circuits and a major concern for the design of power delivery networks (PDNs). Lower supply voltages were made possible with technology scaling, but ...
  • Relative entailment among probabilistic implications 

    Atserias, Albert; Balcázar Navarro, José Luis; Piceno Cabrera, Marie Ely (2019-02-06)
    Article
    Open Access
    We study a natural variant of the implicational fragment of propositional logic. Its formulas are pairs of conjunctions of positive literals, related together by an implicational-like connective; the semantics of this sort ...
  • Task generation and compile-time scheduling for mixed data-control embedded software 

    Cortadella, Jordi; Kondratyev, Alex; Lavagno, Luciano; Massot, Marc; Moral Boadas, Sandra; Passerone, Claudio; Watanabe, Yosinori; Sangiovanni-Vincentelli, Alberto (Association for Computing Machinery (ACM), 2000)
    Conference report
    Open Access
    The problem of optimal software synthesis for concurrent processes to be implemented on a single processor is addressed. The approach calls for the representation of the concurrent processes with Petri nets that give a ...
  • Verification of asynchronous circuits by BDD-based model checking of Petri nets 

    Roig Mansilla, Oriol; Cortadella, Jordi; Pastor Llorens, Enric (Springer, 1995)
    Conference report
    Open Access
    This paper presents a methodology for the verification of speed-independent asynchronous circuits against a Petri net specification. The technique is based on symbolic reachability analysis, modeling both the specification ...
  • Exploiting the locality of memory references to reduce the address bus energy 

    Musoll Cinca, Enric; Lang, Tomás; Cortadella, Jordi (Association for Computing Machinery (ACM), 1997)
    Conference report
    Open Access
    The energy consumption at the I/O pins is a significant part of the overall chip consumption. This paper presents a method for encoding an external address bus which lowers its activity and, thus, decreases the energy. ...
  • Synthesis of synchronous elastic architectures 

    Cortadella, Jordi; Kishinevsky, Michael; Grundmann, Bill (Association for Computing Machinery (ACM), 2006)
    Conference report
    Open Access
    A simple protocol for latency-insensitive design is presented. The main features of the protocol are the efficient implementation of elastic communication channels and the automatable design methodology. With this approach, ...
