Faster Network Verification with Veloce

The Veloce emulation platform is the industry's most complete solution for thorough verification of advanced networking ASICs. Veloce provides the capacity, virtualization, and visibility necessary for ensuring that complex networking ASICs will work on first silicon.

Veloce as a critical verification platform

There are four fundamental required emulation platform capabilities: portability, scalability, virtualization, and determinism.

The Veloce emulation platform provides test portability so that verification steps done in simulation can be
incorporated into the emulation test sequence – and can be used in post-silicon validation. This saves countless hours of rewriting tests for different platforms.

Scalability deals with the size of designs that can be
accommodated. Veloce Strato+ can scale from 40 million gates up to 15 billion gates, allowing a wide range of design sizes. For derivative designs with smaller and larger versions, this provides a single
environment for verifying them all.

The virtualization and determinism characteristics are more subtle. They relate to the ability to verify the
system with realistic traffic in a way that’s easily
debugged.

Given the huge number of modes and configurations in which an ASIC must operate, verification must
include access to vast amounts of real-world traffic. There are two approaches to this: in-circuit emulation (ICE) and virtual ICE.

ICE leverages live data from existing ports, like an ethernet connection tied to the internet or a network tester. But the speeds of live data exceed what can be processed by a virtual ASIC that exists only as a design inside a Veloce emulator. Speed bridges are required
to deliver that data to the Veloce platform at
speeds consistent with the emulation clock rates.
Connecting them usually involves physical access to the emulator – a scenario that is becoming less
common with private data centers hosting Veloce
emulators.
