AgO Inc. has introduced AnXplorer -- a new tool for optimizing analog and RF circuits. Starting with an unsized SPICE netlist, variables for device dimensions and a set of design objectives and constraints, AnXplorer optimizes device sizes by rigorously exploring the design space. By centering the design across all specified, process, temperature and voltage corners, AnXplorer achieves a robust design thereby enhancing the yield and improving the probability of first time silicon success.

A major challenge facing developers of analog and mixed signal ICs is the frequent failure of analog circuits to meet their requirements. Design respins not only significantly inflate the IC’s development costs but also adversely impact the final product’s market entry. Hillol Sarkar, CEO of AgO Inc said “AnXplorer helps analog designers converge on their design objectives rapidly”. He added, “Analog circuits are responsible for 50% of all IC design respins; by automating the analog circuit optimization, AnXplorer can significantly improve the likelihood of first time silicon success”. The tool’s optimization approach rigorously explores the design space searching for robust solutions over all process, temperature and supply voltage corners thereby improving yield.

AnXplorer can fit into commonly used, industry standard, SPICE netlists and simulators, including Synopsys HSPICE, Cadence Spectre and Legend Design Technology MSIM. It runs on the Linux operating system.

A designer can create an unsized circuit, and choose design variables and objectives. AnXplorer will then generate an optimized, centered circuit that meets or exceeds the design objectives across all corners specified by the user. The tool uses a new multi-algorithmic optimization strategy aided by an expert system.
