Analog & Mixed-Signal Verification for Block, Subsystem & SoC

Unverified AMS behaviour can lead to:

• Performance drift in field deployments

• Power inefficiencies

• Silicon re-spins and schedule delays

• Costly re-design cycles

Design verification is no longer a support function. It is a business-critical discipline.

Real-world performance starts with accurate AMS Verification

Analog and mixed-signal designs operate under real-world conditions—where non-ideal effects, noise, and cross-domain interactions directly impact system behavior. From ADC/DACs, PLLs, and PMICs (LDO, DC-DC) to SerDes, RF interfaces, and sensor front-ends, verification must go beyond digital simulation.

Block, subsystem, and full SoC-level AMS verification, covers the complete lifecycle:

• Verification planning to signoff

• Model validation and correlation

• Mixed-signal co-simulation

• Coverage-driven regression and closure

Validate complex behaviors across modalities

Domain expertise meets simulation-driven analysis, equivalence precision, automated regression, and coverage-led verification excellence.
