Multi-core architecture has emerged as the primary architectural choice to achieve power-efficient computing in microprocessors and SoCs. Power gating is indispensable for system power and thermal management and well suited for multi-core architectures. However, checking the power integrity (such as electromigration and voltage drop) of large gated power delivery networks (PDNs) presents a significant...
Due to the rapid growth of traffic in Internet, backbone links of 40 gigabits per second are commonly deployed. To handle high traffic rates, the backbone routers must be able to forward millions of packets per second on each of their ports. Pipelined design can effectively support high speed packets processing. Technology mapping method for sequential circuits in FPGA is playing vital role to pipelined...
Clock mesh has been widely adopted in microprocessor designs to distribute clock signal to clock sink nodes. The primary goal of clock mesh design is to minimize undesired difference in clock arrival time between different sink nodes, which is also known as clock skew. Moreover, the needs for high-performance low-power chip designs impose other constraints on the clock mesh design such as limited...
Nanoscale device characteristics and noise coupling have rendered traditional waveform-based gate delay models increasingly difficult to adopt. While the widely adopted delay models are built upon the assumption of simple ramp-like signal waveforms, realistic signal shapes in nanoscale designs can be far more complex. The need for considering process-voltage-temperature (PVT) variations imposes further...
