From Netlist to Manufacturable Layout: An Auto-Layout Algorithm Optimized for Radio Frequency Integrated Circuits

Layout stitching is a repetitive and tedious task of the radio frequency integrated circuit (RFIC) design process. While academic research on layout splicing algorithms mainly focuses analog digital circuits, there still lack well-developed for RFICs. An RFIC system usually has symmetrical layout, such as transmitter receiver components, low-noise amplifier (LNA), an SPDT switch, etc. This paper aims to address this gap by proposing automated procedure RFICs relying basic device/PCell structure based interconnection among topologies. approach makes in-series generation layouts automatic logic possible, resulting in superior performance compared with related modules Advanced Design System. To demonstrate physical application possibilities, we implemented our algorithm LNA switch circuit.
