Manufacturing is currently undergoing a revolutionary transition with focus shifting from mass production to mass customization. This trend motivates a new generation of advanced manufacturing systems that can dynamically respond to customer orders and changing production environments. It is becoming increasingly important to develop control architectures(More)
In this paper we will discuss a new automatic routing method for printed circuit boards(PCBs). In the field of automatic PCB routing, several “rip-up and reroute” techniques (“dynamic routing”) have recently been proposed. Dynamic routing works by changing one or more previously routed features, and identifying unrouted connections(More)
Recently, simulation and/or formal verification in pre-silicon verification cannot accomplish the whole system-level verification with exhaustive input data and run-time because of lack of sufficient speed and logic capacities. Consequently, post-silicon validation, such as in-circuit debugging, becomes increasingly important. In this paper we propose a(More)
In this paper, we propose a new physical synthesis methodology, PDL, which relaxes the timing constraints to obtain best optimality in terms of layout quality and timing quality. It provides a common database for delay calculation, logic optimization, placement, and routing tools so that they can work and interact closely. We present results on industrial(More)
In this paper we propose a new breakpoint mechanism, which improves controllability of in-circuit debug. It monitors data packets transmitted on the interface port of the target hardware, and triggers a breakpoint when a specified packet is detected among them in realtime. Regarding a data packet as a series of data sequences, we employ an efficient data(More)
