A method for designing an ESD protected analog circuit is described. The
method includes creating an analog circuit design comprising a plurality
of interconnected functional components and circuit-level ESD protection
components with predetermined electric properties for achieving a
predetermined analog performance during normal operation of the circuit
as well as a predetermined ESD robustness during an ESD event on the
circuit. At least one ESD event is simulated on the analog circuit design
to identify at least one weak spot in the circuit. Component-level ESD
protection components are added into the analog circuit design around
each identified weak spot to reduce failure of the weak spot during an
ESD event.
