What is Synthetic Biology?
  • Adding multi-gene DNAs into well-characterized
    organisms to understand biological behavior or
    perform useful functions in diverse areas
    including therapeutics, biosensors, bioenergy,
    bioremediation, chemicals, and materials
    production.

Standardized Parts
  • BioBricks (Tom Knight, MIT) one of the most
    prevalent standards.
  • 2ab Layered assembly (J. Christopher Anderson) is
    another proposal
  • Look to reduce reactions required, increase
    productivity, aid in reliability, and increase
    reuse.

What is Platform-Based Design?
Platform Based Design repeats itself vertically
(fractal nature of design)
Computer Aided Design (CAD) Using a computer to
design something
Spec
Application Instance
Application Space
Electronic Design Automation (EDA) Synopsys,
Cadence, Mentor Graphics
Constraints
  • What a design does.
  • Functionality separated from implementation

Platform
Behavior
Electronic System Level Design (ESL) SystemC,
System Verilog, Blue Spec
Cost Export
Architectural Space
Platform Instance
  • How a design is realized.
  • Implementation separated from functionality.

Cost
Platform Based Design (PBD) Polis, Metropolis,
Metro II
Platform Based Design can be applied
horizontally (different domains)
