(1) Worst corner performance: in red the ones that fail to meet the constraint and in green the ones that meet the constraint The optimization took approximately 10 hours in an Intel® Core i7-3770 @ 3.4GHz workstation with 32Gb of RAM, which is twice the computation effort than the previous optimization presented in Fig. 7, but the obtained POF is much more reliable.…”

“…First-pass fabrication success has always been a constantly-pursued, yet difficult-to-attain, aspiration for the integrated circuit (IC) designer. By ensuring a first-pass success, the designer avoids costly re-design cycles and postfabrication tuning work [1], which considerably decreases the efficiency of the design process. Radiofrequency (RF) circuits are among the most difficult ones to ensure first-pass fabrication success due to their complexity and high operation frequencies.…”

In this paper a design strategy based on bottomup design methodologies is used in order to systematically design a voltage controlled oscillator. The methodology uses two computer-aided design tools: AIDA, a multi-objective multiconstraint circuit optimization tool, and SIDe-O, a tool that characterizes and optimizes integrated inductors with high accuracy (around 1% when compared to electromagnetic simulations). By using such tools, the difficult trade-offs inherent to radio-frequency circuits can be explored efficiently and accurately. Furthermore, with the capability that AIDA has at considering process parameter variations during the optimization, the resulting methodology is able to obtain truly robust circuit designs.

An inductor modeling and optimization toolbox for RF circuit design

This paper describes the SIDe-O toolbox and the support it can provide to the radio-frequency designer. SIDe-O is a computer-aided design toolbox developed for the design of integrated inductors based on surrogate modeling techniques and the usage of evolutionary optimization algorithms. The models used feature less than 1% error when compared to electromagnetic simulations while reducing the simulation time by several orders of magnitude. Furthermore, the tool allows the creation of S-parameter files that accurately describe the behavior of inductors for a given range of frequencies, which can later be used in SPICE-like simulations for circuit design in commercial environments. This toolbox provides a solution to the problem of accurately and efficiently optimizing inductors, which alleviates the bottleneck that these devices represent in the radio-frequency circuit design process.
