Abstract
Power plane structures that may generate high E-fields can be identified and flagged for additional review by representing a boundary of the structures as a function, and evaluating the second derivative of that function. The result can be compared against a threshold value to determine if further review of the structure is desirable.
Claims21
A method comprising:
- representing a boundary of a structure to be formed on a circuit board power plane as a function;
- evaluating a second derivative of the function;
- comparing the second derivative to a threshold;
- and
- flagging the structure if the second derivative exceeds the threshold.
A circuit board comprising a plurality of power planes, the circuit board produced according to a process comprising:
- representing a boundary of a structure to be formed on a power plane of the circuit board as a function;
- evaluating a second derivative of the function;
- comparing the second derivative to a threshold;
- and
- flagging the structure if the second derivative exceeds the threshold.
An information handling system comprising at least one circuit board comprising a plurality of power planes, the circuit board produced according to a process comprising:
- obtaining a description of a boundary of a structure to be formed on a power plane of the circuit board from a computer aided drafting (CAD) file;
- representing the structure as a mathematical function;
- evaluating a second derivative of the mathematical function;
- comparing the second derivative to a threshold;
- and
- flagging the structure if the second derivative exceeds the threshold.
