Overview
​
FMEDA objects are most commonly mapped to design instances. For parts and subparts instance boundaries are always sufficient, but for FM mapping there are cases where module boundaries don’t exist or don’t provide the right level of precision:
-
When a leaf instance doesn’t provide enough resolution – as created by the designer.
-
When a leaf instance doesn’t provide enough resolution – when created by synthesis by flattening a design hierarchy.
-
When an instance is not a leaf, but more resolution is needed for its own (sparse) logic (less common).
In such cases the safety engineer is interested in performing an analysis on design instances to extract elementary functions from the design logic. These are extracted based on selecting points on the design when server as functionality end points or design constraint, and then performing a “cone of logic” analysis.
Safety Planner | Design System
Safety Planner is a web application by Cadence. The app is based on FMEDA technique, and is designed to plan, run and analyze chip verification for the automotive industry. In this project, our goal was to create an efficient work methodology by defining and optimizing user flows.
User Interface Design
I chose a color palette, fonts, icons and components, and designed the visual appearance of the application’s elements, such as the navigation, header and status bars, tables, dialogue boxes, etc. Since this is a safety management tool, it has to constantly evolve with the products, tools and technologies that it measures. This new design system improved the visual appearance and behaviour of the Safety Planner, while also increasing the efficiency of the product designers and developers.
