TinkerCellLite is a Computer-Aided Design (CAD) instrument for synthetic biology. The visual interface allows users to design networks using various biological "parts". Models can include modules and multiple cells. Users can program new functions using C or Python.

TinkerCellLite Features:
1. Customizable hierarchy of biological parts
2. Attributes (e.g. sequence) for characterizing parts
3. Drawing program for designing part graphics
4. Multi-threaded simulations for speed
5. Automatic generation of complex reactions with intermediate steps

Since synthetic biology is an evolving field, here are the issues which were taken into consideration when designing TinkerCell:
1. modeling techniques in biology are not robust
2. experimental techniques are constantly evolving, especially automation and directed evolution methods
3. databases of biological components are still maturing.

TinkerCellLite was designed with the anticipation that the future of synthetic biology will be an interplay between a variety of experimental techniques.
Databases that store results from experiments, and mathematical models explaining different aspects of the experiments were also anticipated.
