This paper presents AIDA, an analog integrated circuit design automation environment, which implements a design flow from a circuit-level specification to a physical layout description. AIDA results from the integration of two in-house tools, namely, GENOM-POF and LAYGEN II. GENOM-POF performs fully automated circuit-level synthesis implemented with a multi-objective multi-constraint optimization approach, which addresses robust design requirements by considering Corners analysis together with an electrical simulator as the evaluation engine. LAYGEN II implements a DRC proved fully automated layout generation based on a sized circuit-level description and high level layout guidelines, described in a technology independent abstract layout template. The expert knowledge is used by LAYGEN II to guide the evolutionary optimization kernels during the automatic layout generation. Moreover, evolutionary computation techniques are extensively used, at both circuit-level and physical-level, as tool to solve design optimization problems. Finally, AIDA environment is demonstrated for the IC design of a classical circuit-level topology and state-of-the-art technology, and validated by industrial simulators and analysis tools, such as, HSPICE® and CALIBRE®.
