Functional rectification in late design stages has been a crucial process in modern complex system design. This paper proposes a robust functional ECO engine, which applies SAT proof minimization and interpolation techniques to automate patch construction to make old implementation and golden specification functionally equivalent. The SAT proof minimization… (More)
Peak-to-average power ratio (PAPR) reduction methods for orthogonal frequency division multiplexing (OFDM) systems commonly use four times oversampling for the discrete-time OFDM signal to approximate the peak of the continuous-time OFDM signal. However, the four times oversampling process increases the computational complexity. In this paper, we propose a… (More)
Typical L-type photonic crystal (PC) microcavities have a dynamic range of approximately 3-4 orders of magnitude in biosensing. We experimentally demonstrated that multiplexing of PC sensors with different geometry can achieve a wide dynamic range covering 6 orders of magnitude with potential for 8 or more orders with suitable optimization.
Constrained random simulation is becoming the mainstream methodology in functional verification. In order to achieve the verification closure, a high-throughput and evenly-distributed constrained random pattern generator has become a must. In this paper, we propose a novel Range-Splitting heuristic and a Solution-Density Estimation technique (RSSDE) to… (More)
Integrating photonic waveguide sensors with microfluidics is promising in achieving high-sensitivity and cost-effective biological and chemical sensing applications. One challenge in the integration is that an air gap would exist between the microfluidic channel and the photonic waveguide when the micro-channel and the waveguide intersect. The air gap… (More)
A photonic crystal (PC) waveguide based optical filter that enables dense integration of high sensitivity L55 PC microcavities for biosensor microarrays is demonstrated.
Constrained random simulation is becoming the mainstream methodology to verify system-wide properties in functional verification. It is a must to develop a high-throughput constrained random pattern generator, which is able to support arbitrary distribution. In this paper, we propose a novel range-splitting heuristic and a solution-density estimation… (More)
