Control unit and method for designing a circuit board of a control unit

A computer-implemented method for designing a circuit board of a control unit, comprising:

• specifying, by a computer processor, a position of a high-impedance circuit component, which has an impedance of 1 kΩ or higher in relation to ground of the control unit, on the circuit board;
• specifying, by the processor, a position, adjacent to the high-impedance circuit component on the circuit board, of at least one conductive protection element electrically connected to ground, such that the at least one protection element, within a protective distance from the at least one protection element, deflects electric field components produced outside the control unit away from the high-impedance circuit component;
• wherein a height of the at least one protection element is at least equal in length to the protective distance.

A non-transitory computer readable storage device storing a computer program that is executable by a computer processor, the program which, when executed by the processor, causes the processor to perform a method for designing a circuit board of a control unit, the method comprising:

• specifying a position of a high-impedance circuit component, which has an impedance of 1 kΩ or higher in relation to ground of the control unit, on the circuit board;
• specifying a position, adjacent to the high-impedance circuit component on the circuit board, of at least one conductive protection element electrically connected to ground, such that the at least one protection element, within a protective distance from the at least one protection element, deflects electric field components produced outside the control unit away from the high-impedance circuit component;
• wherein a height of the at least one protection element is at least equal in length to the protective distance.
