Abstract: With the increase in the density of interconnects and the complexity of high-speed packages, signal integrity becomes an important aspect in the design of modern devices. Circuit designers are constantly in need of robust circuit simulation methods that are able to capture the complicated electromagnetic behaviors of complex circuits, and do it in a fraction of the time taken by conventional circuit simulators. This talk will present the use of the latency insertion method (LIM) as a multi-purpose circuit simulator. By exploiting latencies in the circuit, LIM is able to solve the voltages and the currents in the circuit explicitly at each time step. This results in a computationally efficient algorithm that is able to simulate large circuits significantly faster than traditional matrix inversion-based methods such as SPICE.
