Application hardware simulation to optimize system functions
ICCAD 2009 – China
N. Dufayard, H.Kuo, G.Depeyrot

Introduction Full-chip simulations are very quickly limited by excessive simulation time as well as by the availability of appropriate models. In the same way, simulation of a system cannot be effectively performed at the most accurate level both because it requires too much simulation time and because multi-domain systems cannot be accurately modeled using a …

Selecting an embedded MCU: How to avoid evaluation trap?
IP-ESC’09 Conference – Grenoble, France
D.Maurer, A.Descombes

Abstract The main goal of this article is to focus on the difficulties encountered by SoC integrators when selecting an embedded microcontroller (MCU). Indeed, the selection is based on MCU performances, but the comparison can be difficult and compromised when considering all the parameters influencing these performances. In this article, we will detail how to …

Verification of Mixed Signal System Design accelerated by a new Diagnostic Tool-Kit
ASIM 20. Symposium Simulationstechnik Cottbus, Germany
D.Dammers, F.Tissafi Drissi, M.Giroud, D.Schollän, L. M.Voßkämper

Abstract Time-to-market is still required to decrease in state-of-the-art design processes. Reli- able verification of complete mixed-signal systems, i.e. logic and mixed signal electronics and systems with their attached peripherals, such as sensors and actuators, is needed to be performed quickly to fit in the enhanced design process. While the verification of the logic part, …

Mixed Signal System Design Verification Accelerated With Detector-Based Diagnostic Method
BMAS – 2009 IEEE International Behavioral Modeling and Simulation Conference, San Jose, California, USA
D.Dammers, C.Domingues, D.Schollän, L.M.Voßkämper

Abstract Mixed-signal simulation of complete systems, i.e. pure ana- log/digital systems or electronics with its attached peripher- als, such as sensor and actuator systems, already have a firm place in today’s design process. While the digital part veri- fication has gained a speed increase through the use of Ac- cellera’s Property Specification Language (PSL), the …

Accelerating Mixed Signal System Design Verification using New Diagnostic Method
ASIM – STS/GMMS Workshop, Dresden, Germany
D.Dammers, D.Schollän, L.M.Voßkämper

Abstract The mixed-signal simulation of complete systems, i.e. the electronics with its attached peripherals, such as sensors and actuators, already has a firm place in today’s design process. While the verification of the digital part, mostly implemented in Verilog and VHDL, has gained a speed increase through the use of Accellera’s Property Specification Language PSL, …

Approach for modeling and evaluation of an actuator model for the positioning of read-/write heads in hard disk drives
Multi-Nature Systems (MNS), Ulm, Germany
T.Wiegand, D.Peters, St.Paul, R.Laur, R.Rosing, A.Richardson, B.Vigna, L.Voßkämper

Kurzfassung In diesem Beitrag wird die Modellierung und die Modelloptimierung eines Mikroaktors, der zur Positionierung von Lese-/Schreibköpfen in Festplatten entworfen wurde präsentiert. Zur Modellierung wurde die Verhaltensbe- schreibungssprache VHDL-AMS verwendet. Die Simulation wurde mit dem Verhaltenssimulator SMASH der Firma Dolphin Integration durchgeführt. Zur simulationsgestützten Modelloptimierung wurde das am ITEM ent- wickelte modelbasierte Designoptimierungssystem MODOS eingesetzt. …

Inductorless versus Inductor-Based Integrated Switching Regulators: Bill Of Material, Efficiency, Noise, and Reliability Comparisons
M.Renaud, Y.Gagnon,

Abstract Inductor-based Switching Regulators (SR) have historically represented the preferred architecture for power supplies. Nowadays, for low-power and highly integrated electronic systems, embedded inductor-based SRs show several limitations that can be overcome by the use of inductorless SR architectures. This paper provides a qualitative and quantitative comparison between both types of SR in terms of …

Analog & Mixed Signal IC Debug: A high precision ADC application
F.Poullet

Introduction Increasing pressure on production costs and, more generally, time to market, have impacted all levels of IC design. In this context, one of the major challenges is to avoid silicon failure or yield loss. Indeed, a widely accepted statistic today is that almost half of all designs fail at first silicon. Failure costs are …

A novel technique to create behavioral models of differential oscillators in VHDL-AMS
Xth Inter. Workshop on Symbolic & Numerical Methods, Modeling & Applications to Circuit Design, Erfurt, pp.241-246
M.Kraemer, D.Dragomirescu, R.Plana

Abstract This paper describes an approach to model the transient and steady state behavior of differential microwave oscillators at the system level. Furthermore, phase noise characteristics can be emulated by the resulting models. The mathematical structure consist of a set of algebraic and differential equations that are solved by a VHDL-AMS interpreter. The nonlinearity occurring …
