This paper describes a multilayered triangular subcell method (MTSM) combined with a block-type leapfrog scheme for the fast simulation of a multilayered power delivery network (PDN). An existing triangular subcell method is the method to avoid increasing in the number of meshes around small apertures without degrading the accuracy. In this work, we improve it to be able to deal with the multilayered PDN and combine it with the block-type leapfrog scheme. This combination makes sense because the equivalent circuit model obtained by MTSM has suitable structure for the block-type leapfrog scheme. We demonstrate that the proposed method is more efficient than existing solvers by showing some numerical results.
