Case Study: Renesas Electronics achieves 250× faster verification and cuts performance analysis from 22 to 9 days with Cadence Design Systems

Renesas Deploys Cadence Interconnect Workbench with Palladium Z1 Platform

Renesas, a leading MCU vendor, faced rising design complexity as each new generation integrated more IP and interconnected subsystems. Their previous manual approach to performance and functional verification required days to build testbenches and typically took 22 days for performance analysis, with individual simulations lasting up to 50 hours, making late discovery of system-level bottlenecks a threat to schedules and timely architectural fixes.

To address this, Renesas adopted Cadence’s Interconnect Workbench alongside the Palladium Z1 emulation platform, vManager and Incisive tools, automating testbench generation and running realistic software workloads in hardware-accelerated emulation. The result: performance analysis times fell from 22 to about 9 days, emulation reduced 50‑hour simulations to roughly 12 minutes (a 250× speedup), enabling earlier detection of bottlenecks, faster design iterations and shorter time to market.
