NOD - Nominal Diagnosis
NOD enables the user to perform powerful analyses based on typical (nominal) process characteristics. The designer gets insight into dependencies between performances and parameters with very small simulation effort.

GUI Reference & Performance
Nominal Diagnosis is useful for:
- manual adjustment of a nominal design, that is after generation of a feasible design, but before yield optimization
- analysis of nominal optimization results.
The main window of the Nominal Diagnosis is divided into four parts: a menu, a Selection Box, a Data Display window and a Constraints Window. In order to perform a Nominal Diagnosis, design parameters of the type continuous or manufacturing grid and optionally operating parameters as well as performances and optionally constraints must be defined. The effort for a Nominal Diagnosis grows linearly with the number of parameters and performance groups to be simulated. Before starting the analysis, the parameters and performances for which the diagnosis is to be done can be selected, thereby reducing the simulation effort. The Nominal Diagnosis is based on a linear model built on sensitivities, therefore no additional simulations are necessary in the Nominal Diagnosis itself.
