Floorplanning strategy for mixed analog-digital VLSI integrated circuits

Abstract

A generalization of techniques already in use in digital floorplanning, introducing three types of blocks: analog, digital and mixed, allows the implementation of a floorplanner suitable for mixed analog digital ICs. It makes use of the properties of the blocks to employ different approaches depending on their composition. It makes extensive usage of slicing structures to calculate optimal dimensions and orientations of the blocks, while taking into consideration the constraints due to the coexistence of analog and digital circuitry in the same IC.<>
