CAD Tools for Synthetic Biology
Presentation
The development of microelectronics has been possible through the improvement of the technology, but also thanks to the development, in parallel, of dedicated Computer-Aided Design (CAD) tools, namely Electronic Design Automation (EDA). The development of the same kind of software in the domain of synthetic biology, a Genetic Design Automation (GDA) tool, would be necessary to support the development of this new engineering domain. The aim of our work is to give the outlines of such a GDA by adapting tools and methods that have already proven themselves in the field of microelectronics. The global project is illustrated in the following figure.
The first step to achieve this GDA was to design an automatic models generator to create models of biosystems in hardware description languages (HDLs) commonly used in microelectronics (like VHDL-AMS). The development of this tool began as part of the iGEM 2011 and was carried out by the ENSPS-STRASBOURG team.
In the following sections, you will find a video tutorial to become familiar with the handling of the software, the latest version of the software for download, as well as three examples of biosystems modeled using this software.
Tutorial
A video tutorial of the automated model generator which was record for iGEM 2011 is available on Youtube. Only minor graphical modifications on the interface were done since this video.
Downloads
Automated model generator
You can download the software at this link :File:Model_Generatorv0.1.zip.
Compatibility : Windows XP or superior.
After entering the system, this software generates different models files. However, to simulate the system, Dolphin SMASH is requiered.
