Acquired Experiences with Computational Tool MSSV Used in Electronic Circuit Design

The top-down methodology and CAD tools are important in development of electronic circuits. Mainly when design is in high level of abstraction and many levels of representation can be used to modeling the electron ic circuits. Th is way is necessary to use a tool to execute the synthesis of models, i.e ., changing a representation in high level of abstraction in another in lower level. This paper presents the experiences in use synthesis computational tools to support the synthesis of digital-to-analog converter models by translating between different tools used in modeling systems and electronic circuits. This tool is named MSSV and works direct ly with the following two commercial tools: MATLAB / Simulink and SystemVision. The MSSV synthetizes block diagram developed in Simulink representing a mixed-signal circuit into a lower level of abstraction in VHDL-AMS. To compare the simulation results was used SystemVision environment, because the MSSV generates all design structure to SystemVision. The method validation was performed by analyzing the power spectral of signal obtained by discrete Fourier transform of three d ifferent kinds of digital-to-analog converters.
