ABSTRACT:
This invention provides directional connectivity described by the interconnections of the blocks in the schematic or netlist that are used to propagate impedance data from one block to another. The propagation of impedance data for discrete time based simulation programs allow for the simulation under less than ideal termination conditions between the blocks. This invention also supports functionality where the input impedance and output impedance of each block are not perfectly terminated. This assumption can lead to very significant modeling errors in the simulated results. In general, termination impedances are complex frequency dependent functions that result in frequency dependent mismatch losses between the blocks. This invention allows for the propagation and calculation of impedance mismatches between the various blocks.
