Abstract:
Faithfully representing small delay variations caused by transitions on different inputs in close temporal proximity is a challenging task for digital circuit delay models. In this paper, we show that a simple hybrid model, derived from considering transistors as ideal switches in a simple RC model, leads to a surprisingly accurate model. By analytically solving the resulting ODEs for a NOR gate, explicit expressions for the delay are derived. In addition, we experimentally compare our model's predictions to SPICE simulations and to existing delay models.
