Case Study: Realtek achieves faster, large-capacity mixed-signal verification and first-time silicon success with Cadence Design Systems' Virtuoso Multi-Mode Simulation

Realtek - Customer Case Study

Realtek, a Taiwan-based design house specializing in mixed-signal processors, memory, and ultra‑wideband devices, faced growing pressure to shorten design cycles and reduce time to market as designs became larger and more complex. To stay competitive, the company needed faster, more thorough simulation and verification for nanometer-scale mixed‑signal chips.

Realtek adopted Cadence Virtuoso Multi‑Mode Simulation—including Virtuoso UltraSim Full‑Chip Simulator, AMS Designer with UltraSim Analog Solver, and Spectre—reusing existing databases and using token licensing for flexible access. With Cadence engineering support and an integrated flow, verification scaled up quickly (a 78K‑element design with two PLLs simulated in 48 hours), delivering faster cycles, higher first‑time silicon success, increased productivity, and improved customer satisfaction and profitability.
