Development of a time-domain simulation methodology for the hybrid phase-pole interconnect macromodel

A new hybrid phase-pole macromodel (HPPM) was recently developed for modeling lossless interconnects. Now this HPPM is applied for the transient simulation of interconnects. First, the time-domain waveform is expanded in terms of triangular expansion functions. A knowledge of the triangle impulse response (TIR), which is represented in the form of a HPPM, then allows for the time domain simulation of the line voltage. A recursive convolution algorithm is adopted to carry out the required convolutions efficiently in the transient simulator. Combining this transient simulator with an HPPM extractor yields an efficient transient interconnect signal analysis tool. Work is ongoing to extend the technique to lossy interconnects.
