An interactive visualisation tool for analog design

The design of an analog circuit, particularly to accommodate component tolerances, can benefit immensely from insight into the complex relations between designable parameters and circuit performances. Such insight is currently acquired via tedious exploration, but this exploration can now be significantly enhanced by an interactive tool called the Influence Explorer. Its graphical presentation of precalculated data relating parameters and performances allows fluent qualitative exploration, including the discovery of important trade-offs and correlations. The Influence Explorer also provides a smooth transition to quantitative design decisions, including those involved in tolerance design
