Abstract :
Projective convolution (PC) is a provably passive and numerically well-conditioned model-order reduction technique for large RLC circuits including those with floating capacitors or inductor loops. Unlike moment-matching which operates in the frequency domain, PC is positioned squarely in the time domain: it matches the impulse response of a circuit by projecting with the Krylov space formed by solving the discretized differential equations of the circuit. PC gives excellent results for coupled lines, large RLC meshes, and clock trees
