Ltd offer a complete Spectrum of solutions from Embedded Development Environments, RTOS, MEMS Design and VLSI Design. FTD’s partner Coventor offers two complementary products, MEMS+® and CoventorWare®, that together provide a comprehensive platform for MEMS development. These tools support variety of physics that occurs in MEMS, including mechanical, electrical, piezo-electrical, piezo-resistive, fluidic and packaging effects. Coventor offers solutions that enable co-design of MEMS and the accompanying systems and electronic circuitry (IC) that complete a packaged MEMS product. This requires integration with non-MEMS design tools and methodologies, such as the system modeling and EDA tools commonly used by IC and electronics engineers.

Next session began with the hands-on session on MEMS+ and Coventorware software. The software is a MEMS CAD tool for integrating the VLSI circuitry on Cadence tool with the design of the MEMS sensor on Coventorware tool which is a MEMS CAD tool. Technical team of FTD infocom gave insight idea of how to use the software for the design of the MEMS devices. The presentation includes the usage of tool such as how to define the material properties, how to add new materials to the material library. They gave in detail presentation on the MEMS fabrication process options in the tool and how to use them. Then the presentation has continued with the how to mesh a model, how to apply boundary conditions and how to analyze the results. It was totally a useful presentation for the new researchers who wants begin their research in the area of NEMS and MEMS.

Second day session continued with the presentation on how to interface MEMS device with the VLSI signal processing circuitry using MEMS+ CAD tool. The presentation was completely on VLSI signal processing circuitry by interfacing MEMS+ tool with the MATLA and CADECE tools.

Next session was complete hands-on session on Coventerware MEMS CAD tool. For the hands on session technical team has taken MEMS accelerometer as the example and gave complete design and simulation overview. The session started with the explanation of the MEMS Accelerometer working principle and the design constraints in the tool. Then the hands on started with the each individual provided a individual PC with the trial version of the software.
