Abstract: Methods and structure for improved simulation of CDM ESD events and for remediation of circuit designs correcting for previously inexplicable damage to core circuits of an application circuit design caused by such events. Features and aspects hereof note that such previously inexplicable damage to core circuits of an application circuit design is caused by inductive coupling between the non-core circuits and the core circuits of an application circuit design. Improved simulation techniques in accordance with features and aspects hereof may predict where such inductive coupling may cause damage to core circuits. Other features and aspects hereof may alter an application circuit design to provide remediation by automated insertion of additional buffer circuitry to core traces of the core circuitry that may be impacted by such inductive coupling.

Abstract: Methods and structure for improved design remediation for previously inexplicable damage to core circuits of an application circuit design caused by CDM ESD events. Features and aspects hereof note that such previously inexplicable damage to core circuits of an application circuit design is caused by inductive coupling between the non-core circuits and the core circuits of an application circuit design. Features and aspects hereof automatically alter an application circuit design to provide remediation by various techniques to reduce the magnitude of such inductive coupling and to thereby reduce susceptibility of the application circuit to damage from CDM ESD events. The modifications may be enforced as rules during initial design of the application circuit or as reconfiguration of a design in response to simulation to discover inappropriate coupling in the design.
