## Prototype your design! Robert Griesemer dotGo 2016, Paris ## Getting to good software design • Literature is full of design paradigms • Usually involves ○ Design docs Feedback from reviewers • Often a “dry” exercise ☐ No software is created until design is “completed” ## How can we tell if we have a good design? ## Elsewhere, design thinking requires prototyping Try stuff Reframe problems mutation Define appropriate methods on that type A Go implementation allows us to explore our design. ## Key missing feature: Nice notation ### The work-around, accessor methods for multi-dim. index

Design Patterns are reusable elements of design that may help aid in making software more maintainable, flexible, and extensible. The term 'design patterns' can be traced Four' book Design Patterns, in which common software design patterns were defined and categorized. In this talk, you will learn the fundamentals of the creational, structural, and behavior design patterns

updated in pcbnew by regenerating the netlist and reading it in pcbnew again. Pcbnew provides a design rules check (DRC) tool which prevents track and pad clearance issues as well as preventing nets from aren’t connected in the netlist/schematic. When using the interactive router it continuously runs the design rules check and will help automatically route individual traces. Pcbnew provides a rats nest display trapezoidal and complex form, automatic layout of coils on the printed circuit, etc). #### 1.2. Principal design features The smallest unit in pcbnew is 1 nanometer. All dimensions are stored as integer nanometers
