For the design and verification of a heterogeneous system architecture containing analog, digital, and software functionality, the use of modern languages and advanced Electronic System-Level (ESL) top-down design methodologies becomes fundamental. This paper will present the industrial application of the SystemC analog/mixed-signal (AMS) extensions in combination with SystemC and other C++ libraries,...
Co-simulation provides an architect or a designer the freedom to change the implementation of a sub-module and analyse the design. Variational analysis during design procedure is an important tool to ensure higher-yield during production. State of the art co-simulators uses Monte Carlo analysis method for variational analysis, which is a multi-run method, slow and outcomes are not completely covered...
In case of architectural designing of an analog system/sub-system, accurate and sufficient estimation of non-idealistic parameters are of highest importance as it impacts strongly on the cost and performance of the target implementation. Manual optimization of such a system which is a multi-dimensional complex design-space, is prone to manual errors, limited by human imaginations and should be avoided...
Model based design of system architectures and optimization of those architectures at highest level of abstraction is gaining importance in modern day system level applications and designs. However, these complex systems need to be resolved and dened accurately at system level which is done by modelling of complete system. The process of efficient modelling and use of those models to optimize the...
This session includes contribution that advance state of the art in verification of mixed-signal systems. The first paper gives a method to emulate analog loads for in-lab experiments. The second paper describes a method for more efficient simulation of linear systems in SystemC AMS. The third paper proposes a method for specifying assertions for analog circuits.
Analog Front End of any measurement devices suffer from the error arising out of the additive analog device offsets. Existing energy measurement device architectures uses a high pass filter (or a D.C. notch filter) at the output of the current channel Analog to Digital Converter (ADC) to cancel offsets generated by analog front-end, which makes it failing to measure the power consumption in a non-linear...
Programmable Gain Amplifiers (PGA) are the most important component in a signal chain as it poses a Signal-to-Noise performance and Total Harmonic Distortion (THD) bottleneck for any signal path. Due to it's massive size in silicon and respective performance, parametric optimization of a PGA is of utmost importance beforehand. In this article we design a high gain (80 dB), high bandwidth (32 kHz)...
For the design of complex systems both accurate and abstract models are required. Especially for analog subsystems this trade-off is difficult. The new SystemC AMS extensions [7] offer high simulation performance, but also serious restrictions. In this paper we model a switched capacitor sigma delta modulator using the SystemC AMS extensions. The model combines high simulation performance while modeling...
