This paper proposes an improved charge pump circuit for low voltage RFID applications. The architecture of charge transfer switch based dynamic charge pump has been modified to provide higher output voltage than existing one. This has been achieved by replacing the diode with a charge transfer block at the last stage of the dynamic CTS charge pump. The modified charge pump eliminates the threshold...
This paper discusses a methodology used on an industrial hardware development project to validate various cache-coherence protocol components. The idea is to use a high level model (HLM) written in Murphi for model checking purposes, and then to use the HLM as a checker during dynamic (i.e. simulation based-) validation of the RTL. Such a checker requires a formal notion of what it means for the RTL...
In a pervasive sensor system, application entities may use the available infrastructure resources such as sensing devices, actuators, wireless modules and gateways to accomplish various tasks. For example, a group of humans/robots may use the infrastructure to track the current location of the group members. Many such tasks require a service which keeps track of the order of occurrence of events in...
Using RTL (Register Transfer Level) models for the verification of complex hardware designs involves reducing the state space of designs using various abstraction techniques. In this paper, we propose faster and earlier verification of hardware designs at a level of abstraction above RTL. We consider a high-level (above RTL) hardware model that uses atomic rules to describe the behavior of a design,...
