... сквозное отверстие и через него сигнал переходит на другой слой.
На месте этого отверстия расположен пин,через который сигнал должен проходить от слоя к слою,но
этого не происходит..
I don't really get that. "пин" you mean a via hole or a port?
Sounds like there might be a problem with your model, or you simply forgot to include 0Hz point in MoM simulations.
Also remember to define your via holes as via layer in the substrate definition. Built-in 3D viewer can help to debug your 3D model. Look at at your model in 3D and make sure that your vias look right and ports are defined between correct layers.
