Frequency of the digital signal in PCBs has remained at about 1 GHz, while that in VLSIs become more than several GHz. The frequency gap comes from signal integrity (SI) deterioration in PCB in GHz-domain. To overcome this problem, we have already proposed segmental transmission line, in which genetic algorithm is used to solve the combinatorial explosion problem in the design. In this paper, we propose a novel fitness based on the eye-diagram, which is widely and generally used for SI evaluation in the high-speed interconnection design field. And we also propose a high-speed eye-diagram calculation method based on virtual eye-diagram. This eye-diagram is constructed by superposing the single-shot pulse responses and can reduce the simulation time. The simulation experiments demonstrate that our proposed fitness increases the eye height and eye width by 3.07 and 1.06 times, respectively, compared with the conventional one. |
