Model order reduction (MOR) techniques are widely used in practical design of integrated circuits. The projection methods of MOR are based as a rule on Krylov subspace methods. But the trends of electronic industry advance new requirements for MOR techniques. In particular the actual important problem of MOR is the problem of reduction of the networks with many inputs and outputs. As known “Krylov subspace projection methods will be extremely inefficient“ for reducing the models with many ports. For instance the number of basic vectors added to the subspace in the case of multiport applications for block Krylov subspace methods is often proportional to the number of inputs. But in practical MOR problems the result order of reduced model obtained by this way is often much larger than it is required to provide desired accuracy. To reports list |
