A method involves determining failure in time rate for a circuit. The method may include obtaining circuit data regarding a circuit. The circuit may include a first wire segment and a second wire segment. The method may further include obtaining reliability data. The reliability data may describe a failure of the circuit over a pre-determined time period. The method may further include obtaining a thermal map. The method may further include determining a first failure rate for the first wire segment of the circuit. The first failure rate may be a probability that the first wire segment fails in a predetermined amount of time. The method may further include determining a second failure rate for the second wire segment of the circuit. The method may further include generating a model of the circuit. The model of the circuit may describe the first and the second failure rate of the circuit.

Method and system for determining circuit failure rate

Improved performance of simulation analysis of a circuit with some non-linear elements and a relatively large network of linear elements may be achieved by systems and methods that partition the circuit so that simulation may be performed on a non-linear part of the circuit in pseudo-isolation of a linear part of the circuit. The non-linear part may include one or more transistors of the circuit and the linear part may comprise an RC network of the circuit. By separating the linear part from the simulation on the non-linear part, the size of a matrix for simulation on the non-linear part may be reduced. Also, a number of factorizations of a matrix for simulation on the linear part may be reduced. Thus, such systems and methods may be used, for example, to determine current in circuits including relatively large RC networks, which may otherwise be computationally prohibitive using standard simulation techniques.
