The purpose of this research is to evaluate the design risk of the capacitive waveform recorder and extract the critical levels to prevent its occurrence in the waveform recorder. The simulated outputs were extracted using Proteus software in order to select the circuit with appropriate accuracy.In this research, FMEA method is used to evaluate failure modes. All parts of the waveform recorder were evaluated and states, effects and causes of failure were calculated and evaluated. Then the risk number of each failure was calculated and its crisis level was prioritized.The purpose of FMEA is to support decisions that reduce the probability of failures and their effects and help improve outputs. FMEA documents can only include a brief statement of proposed exposures or design changes: replacing elements with more reliable one, introducing backup systems, and new or improved methods that limit damage.In conducting the research, the general process for FMEA evaluation was determined. Then, by interviewing experts in the field, the failure modes of the design of the capacitor waveform recorder were analyzed. Critical situations were extracted and countermeasures were suggested to improve performance. Two methods of simulation and interview were considered to collect information. The relationship between circuit design cost and design error analysis was extracted and it was observed that with the increase of DFMEA, in addition to increasing the number of parts and increasing the risk of failure, the cost of circuit design and construction and measurement error increases.
