PASTEL is a parameterized memory characterization system which extracts the characteristics of ASIC on-chip-memories such as delay, timing and power consumption which are important in lsi logic design. PASTEL is a fully-automated process from exact wire-RC extraction through circuit reduction, input vector generation, waveform measurement, data-sheet and library creation. The circuit reduction scheme can reduce the circuit simulation time by 2 order of magnitude while maintaining delay error within 100pSec of exact simulation.

This paper describes a gate-level power minimization methodology using dual supply voltages. Gates and flip-flops off the critical paths are made to operate at the reduced supply voltage to save power. Core technologies are dual-V DD circuit synthesis and P&R. We give a brief overview on existing low-power EDA technologies as background and discuss advantages and challenges of the dual-VDD approach. Through real design examples, we will show that the approach reduces power effectively while keeping the performance at negligible area overhead. © 2000 IEEE.

Measurement of proton-induced helium production cross sections for aluminum and nickel below 16 MeV

Proton-induced He production cross sections, (p, He), for Al and Ni have been measured up to 16 MeV by using a He accumulation method. The reliability of the present experiment was confirmed by performing three kinds of experiments for the Al(p, He). The sample structure or the manner of measuring the number of bombarding protons differs in each experiment. A comparison of their results shows that it is valid to install an Al sample in a Faraday cup for determination of the absolute number of incident protons and to sandwich a sample sheet by two Au foils to catch outgoing alpha-particles from the sample surface layer for measuring the all He produced in the sample.

Interconnect delay is dominant in today's high speed Vlsi circuits and there have been various studies on ways to resolve it. A repeater insertion tool "RePertory" has been developed to solve the interconnect timing problem on a 300 MHz 128-bit 2-way superscalar microprocessor. Because of its practical simple algorithm, the location of over 5700 repeaters distributed over 5 modules is calculated in 26 minutes on 5 UltraSPARC-II 360 MHz in parallel. This paper describes the goals of RePertory for this project, the timing improvement flow with RePertory, the results and analysis of this repeater insertion method.

Find all solutions of piecewise-linear resistive circuits using an LP test

IEEE Transactions on Circuits and systems I: Fundamental Theory and Applications 2000年第7期47卷 1115-1120页

An efficient algorithm is proposed for finding all solutions of piecewise-linear (PWL) resistive circuits using linear programming (LP). This algorithm is based on a simple test (termed the LP test) for nonexistence of a solution to a system of PWL equations in a given region. In the LP test, the system of PWL equations is transformed into an LP problem, to which the simplex method is applied. Such an LP problem is obtained by surrounding the PWL functions by rectangles. It is shown that the LP test can deal with nonseparable functions of more than one variable by using more than two-dimensional rectangles. It is also shown that, for bipolar transistor circuits, the LP test becomes more efficient and more powerful by surrounding the exponential functions by right-angled triangles. The proposed algorithm is simple, efficient, and can be easily implemented.

There are many communication circuits driven by multi-tone signals such as modulators and mixers. If the output frequency components are largely different to each other, the brute force numerical method will take an enormous computation time to calculate the steady-state responses, because the total period becomes very long. In this paper, we show a SPICE oriented algorithm based on the frequency domain relaxation method which can be efficiently applied to relatively large scale ICs.

We studied the optimization of an ESD protection circuit based on MM and HBM test results using a test element group (TEG) created in a fully silicided 0.1 /spl mu/m CMOS process. We concluded that the change in drain area and channel width had different effects on the ESD robustness of different test items because the type of operating ESD protection element was determined by the polarity of the ESD surge applied. In addition, we found that, due to the formation of silicides in a source and drain contact, the dimensions around the contact had less influence on ESD robustness, while the channel width had a large influence on ESD robustness.

We present the design and implementation of the Illuminator, a preliminary sensor network-based intelligent light control system for entertainment and media production. Unlike most sensor network applications, which focus on sensing alone, a distinctive aspect of Illuminator is that it closes the loop from light sensing to lighting control. We describe the Illuminator's design requirements, system architecture, algorithms, implementation and experimental results. To satisfy the high-performance light sensing requirements of entertainment and media production applications, the system uses the Illumimote, which is a multi-modal and high fidelity light sensor module well-suited to wireless sensor networks. The Illuminator system is a toolset to characterize the illumination profile of a deployed set of fixed position lights, generate desired lighting effects for moving targets (actors, scenic elements, etc.) based on user constraints expressed in a formal language, and assist in the set up of lights to achieve the same illumination profile in multiple venues. After characterizing deployed lights, the Illuminator computes at run-time optimal light settings to achieve a user-specified actuation profile using an optimization framework based on a genetic algorithm Uniquely, it can use deployed sensors to incorporate changing ambient lighting conditions and moving targets into actuation. With experimental results, we demonstrate that the Illuminator handles various high-level user's constraints and generates optimal light actuation profile. These results suggest that our system should support entertainment and media production applications.
