AIDA: Robust layout-aware synthesis of analog ICs including sizing and layout generation

Abstract

This paper presents AIDA 2015, the newest version of AIDA, an analog integrated circuit design automation environment, which implements a design flow from a circuit-level specification to physical layout description. AIDA results from the integration of two in-house tools, namely, AIDA-C and AIDA-L. AIDA-C consists of an innovative layout-aware optimization-based methodology for automatic sizing of analog ICs. AIDA-L, the layout generator, implements a fully automated layout generation methodology. AIDA-L provides two alternative floorplanners, a template-based and an optimization-based. The placed modules, whose layouts are spawned by the in-house module generator, are fed together with the node electric-currents to the electromigration-aware multi-port Router that finalizes the layout. Finally, the AIDA environment, www.aidasoft.com, is demonstrated for analog IC design, sizing and layout generation, using state-of-the-art technologies, and validated by industrial simulators and analysis tools, such as, HSPICE®, SPECTRE®, ELDO ®, or CALIBRE®.
