“…Therefore, the system-level specifications may not hold once circuits are sized, leading to re-design cycles. Some approaches address this issue, designing RF systems by sizing all devices simultaneously [14], [15]. However, they use first-order analytical equations to estimate circuit performances that do not account for all nonidealities and use ideal models, which are inaccurate, for passive components.…”

This paper presents an innovative yield-aware synthesis strategy based on a hierarchical bottom-up methodology that uses a multiobjective evolutionary optimization algorithm to design a complete radiofrequency integrated circuit from the passive component level up to the system level. Within it, performances' calculation aims for the highest possible accuracy. A surrogate model calculates the performances for the inductive devices, with accuracy comparable to full electromagnetic simulation; and, an electrical simulator calculates circuit-and system-level performances. Yield is calculated using Monte-Carlo (MC) analysis with the foundry-provided models without any model approximation. The computation of the circuit yield throughout the hierarchy is estimated employing parallelism and reducing the number of simulations by performing MC analysis only to a reduced number of candidate solutions, alleviating the computational requirements during the optimization. The yield of the elements not accurately evaluated is assigned using their degree of similitude to the simulated solutions. The result is a novel synthesis methodology that reduces the total optimization time compared to a complete MC yield-aware optimization. Ultimately, the methodology proposed in this work is compared against other methodologies that do not consider yield throughout the system's complete hierarchy, demonstrating that it is necessary to consider it over the entire hierarchy to achieve robust optimal designs.

“…Some other approaches have tried to reach the lower circuit sizing level. In [18], the circuit specifications provided by the tool in [16] are used to size a low-noise amplifier (LNA) and a mixer. The circuit performances are estimated using first-order analytical equations, that do not take into account all nonidealities.…”

“…Therefore, these components have to be synthesized after the circuit design, and there is no guarantee that the value required for the passive is achievable in the adopted technology. As reported in [18], some components had to be iteratively tuned by more than 50% from its initial value in order to meet the circuit specifications.…”

In recent years there has been a growing interest in electronic design automation methodologies for the optimizationbased design of radiofrequency circuits and systems. While for simple circuits several successful methodologies have been proposed, these very same methodologies exhibit significant deficiencies when the complexity of the circuit is increased. The majority of the published methodologies that can tackle radiofrequency systems are either based on high-level system specification tools or use models to estimate the system performances. Hence, such approaches do not usually provide the desired accuracy for RF systems. In this work, a methodology based on hierarchical multilevel bottom-up design approaches is presented, where multi-objective optimization algorithms are used to design an entire radiofrequency system from the passive component level up to the system level. Furthermore, each level of the hierarchy is simulated with the highest accuracy possible: electromagnetic simulation accuracy at device-level and electrical simulations at circuit/system-level.
