Abstract :
In simulation of a mixed-signal IC, a hypermodel must be inserted if a digital port and an analog port are connected. In order to obtain reliable circuit behavior, terminal characteristics of the hypermodel should be close enough to that of the digital circuit output. This article describes the methodology that a hypermodel library can be generated automatically based on the information of a cell library of designer´s selection. A program is developed based on this methodology. Comparison of simulation results on characteristics of circuit level cell model and that of a selected hypermodel is also provided. The results show good fit and the generated hypermodel library can be used confidently in mixed-signal IC simulation.
