ItDD - Combinational Design Procedure

Noting down goals and functionality

Lay out all the details for the project

• Specification

• Formulation

• Optimisation

• Tech Mapping

• Verification

Take your specification, draw the truth table and the inital boolean equations which go along with it and come up with the outputs.

• Specification

• Formulation

• Optimisation

• Tech Mapping

• Verification

Using boolean algebra or Karnaugh Maps to simplify the formula. You draw the logic diagram at the end.

• Specification

• Formulation

• Optimisation

• Tech Mapping

• Verification

Take the result of the optimisation and build the components. Take the real world stuff and use that to fit the design which you completed in the optimisation stage.

• Specification

• Formulation

• Optimisation

• Tech Mapping

• Verification

Through simulation or testing, you make sure the result meets the specification and completes and meets the requirement in the specification stage.
