Custom VLSI design at the switch level is commonly applied when a chip is required to meet stringent operating requirements in terms of speed, power, or area. ATPG requires gate level models, which are verified for correctness against switch level models. Typically, test models are created manually from the switch level models - a tedious, error-prone process requiring experienced DFT engineers. This paper presents an automated flow for creating gate level test models from circuits at the switch level. The proposed flow utilizes Motorola's Switch Level Verification (SLV) tool, which employs detailed switch level analysis to model the behavior of MOS transistors and represent them at a higher level of abstraction. We present experimental results, which demonstrate that the automated flow is capable of producing gate models that meet the ATPG requirements and are comparable to manually created ones.
