 iBioSim is a computer-aided design (CAD) tool aimed for the modeling, analysis, and design of genetic circuits. 
 While iBioSim primarily targets models of genetic circuits, models representing metabolic networks, cell-signaling pathways, 
 and other biological and chemical systems can also be analyzed.
