OPUS is a Cadence plug‑in that automates global optimization of analog, RF, and mixed‑signal circuits, sizing transistors, capacitors, and inductors across PVT corners while meeting yield targets. The on‑premises engine evaluates billions of design points in minutes, delivering Pareto‑optimal trade‑offs for gain, bandwidth, noise, power and area without manual sweeps.

Problem
Analog and mixed‑signal circuit designers must manually sweep vast parameter spaces to meet specifications across process, voltage, and temperature (PVT) corners, leading to long iteration cycles, low yield, and delayed tape‑out. The combinatorial explosion of device widths, lengths, and bias settings makes exhaustive exploration impractical with conventional simulation flows.
Solution
OPUS embeds a high‑performance global optimization engine directly into Cadence‑based analog design flows, enabling automated sizing of transistors, capacitors, and inductors while accounting for PVT variations and yield targets. The tool performs numerical optimization and statistical sensitivity analysis on‑premises, so proprietary design data never leaves the customer’s environment. By exploring multi‑dimensional design spaces in minutes, OPUS reduces simulation time by 20‑30× and delivers robust, high‑yield solutions for gain, bandwidth, noise, power, and area constraints. Designers interact with a visual “optimization cockpit” that presents trade‑off curves and top‑ology alternatives, allowing rapid convergence to the global optimum without manual sweeps. Seamless integration with existing Cadence toolchains and PDK‑agnostic support ensures the workflow fits into current tape‑out schedules.
Target Audience
Primary customers are analog, RF, and mixed‑signal design teams in semiconductor companies, ASIC houses, and IP vendors who need to accelerate circuit sizing and improve yield within Cadence‑based design flows.
