DAISY: a simulation-based high-level synthesis tool for ΔΣ modulators

A GUI driven Σ-Δ modulator design, evaluation and measurement tool with a view to practical implementation

“…Thus, several design automation tools for Low-Pass (LP), and Band-Pass (BP) Σ−Δ modulators at the system level were reported in the literature [2]- [4]. The most common approach to automate the design procedure is based on iterative performance optimization via a performance evaluation loop using statistical methods or behavioral simulations for the desired modulator parameters [3], [5], [6]. The other common approach is the automation of the modulator coefficients by optimizing the Noise Transfer Functions (NTF) or Signal Transfer Functions (STF) for the desired design specifications.…”

Genetic-based high-level synthesis of modulator in SystemC-A

“…Ruiz-Amaya et al [6] develop a toolbox in MATLAB/Simulink environment to optimize the coefficients of the selected ΣΔ modulator structures using an adaptive statical optimization algorithm based on simulated annealing. A behaviour simulation-based synthesis tool(DAISY) is programmed in C language by Francken et al [7]. A set of selected topologies are stored in a library.…”

“…In order to decrease the complexity of the design procedure, several tools for automated ΣΔ modulator design have been developed recently [3], [4], [5], [6], [7], [8]. Most of the methodologies are based-on the optimisation of the coefficients of signal paths for preset popular ΣΔ modulator topologies [4], [5], [6].…”

Systematic Design Exploration of Delta-Sigma ADCs

“…CAD tools for design and optimization of ADCs have also been reported. In [10], a tool is described which helps the designer choose the optimal solution from a predefined set of topologies with fixed filter coefficients, which might be a local optimum in the entire ADC design space. The tool also determines the minimum values for the circuit-level parameters like operational amplifier gain and bandwidth.…”
