Abstract--We have proposed, in this paper a, TCAD/DA methodology for MPU and ASIC with updated processes and devises, which allow a predictive chip-design with quick quantitative correlation studies between process-recipe and CKT & delay parameters required in DA works. Effects of statistical process variation on 0.35um CMOS have been rigorously characterized with a new global TCAD calibration ...

   In this paper we implement a simple DC model for CNTFETs already proposed by us in order to carry out static analysis of basic digital circuits. To verify the validity of the obtained results, they are compared with those of Wong model, resulting in good agreement, but obtaining a lighter ensuring compile and shorter execution time, which are the main character...

Wave-pipelining is a method of high-performance circuit design which implements pipelin-ing in logic without the use of intermediate latches or registers. This paper presents a tutorial of the principles of wave-pipelining and a survey of recent wave-pipelined VLSI chips and CAD tools for the synthesis and analysis of wave-pipelined circuits. Wave-pipelining has recently drawn considerable inte...

As the number, and diversity, of computer aided design tools used by VLSI circuit designers continues to grow, the need for CAD frameworks increases. While a precise definition of a CAD framework is difficult to give, it is convenient to view a CAD framework as a collection of underlying facilities and services that support activities performed by CAD tool developers, CAD system integrators, an...

In this paper a novel design of all-optical half-subtractor based on nonlinear directional coupler is proposed. By using four waveguides and appropriately adjusting the refractive indices and selecting the proper length of waveguides, halfsubtractor function can be obtained. The operation of this function is simulated by RSoft CAD-Layout (BeamPROP) simulator. The simulation results confirm the ...

In this report, we firstly introduce several CAD tools in FPGA architecture and CAD research. Then we outline a typical CAD flow and use these tools to evaluate it. In the demo experiment, we select a small MCNC benchmark circuit as an input to the CAD flow, and then we give our results. Finally, we draw some conclusions and make plans for our future research.

echnology computer-aided design (TCAD) is the software tool set that allows integrated circuit T (IC) tech nologists to develop new processes and devices without having to build costly test lots. TCAD can potentially provide process engineers the same benefits that electronic circuit CAD (ECAD) has provided to circuit designers. Circuit designers can design, lay out. and test new circuits witho...
