  • Publication number: 20240078370
    Abstract: Various techniques are disclosed for automatically generating sub-cells for a non-final layout of an analog integrated circuit. Device specifications and partition information for the analog integrated circuit is received. Based on the device specifications and the partition information, first cut locations for a first set of cuts to be made along a first direction of a non-final layout of the analog integrated circuit and second cut locations for a second set of cuts to be made along a second direction in the non-final layout are determined. The first set of cuts are made in the non-final layout at the cut locations to produce a temporary layout. The second set of cuts are made in the temporary layout at the cut locations to produce a plurality of sub-cells.
