Most techniques for Failure Mode and Effect Analysis (FMEA) of the electronic equipment and circuits have up till now been based on manual examination of the circuit schemes. This technique has often been considered to be arduous and time consuming. No computer-based methods to perform the FMEA have been available, and it has become obvious that the usual circuit analysis programs are not suitable for this purpose. However, the extended use of electronic equipment in controlling automatic machines has increased the need to evaluate the safety and security of the system as effectively as possible. This is one of the main ressons for starting the generation of this computer program as a tool for FMEA of electronic circuits.
