VeriFast BoW
BoW - Bunch of Wire VIP
VeriFast BoW is an innovative Verification IP (VIP) solution designed to accelerate verification of System-on-Chip (SoC) designs that leverage Open Domain-Specific Architecture (ODSA) chiplet interconnect. It specifically targets the link layer to PHY on the Bunch of Wires (BoW) interface.
By adopting VeriFast BoW, you can significantly reduce verification cycle times for SoCs that integrate chiplets from various vendors. This enables you to rapidly assemble domain-specific products with minimal verification hurdles. VeriFast BoW offers a rich set of features to enhance your verification productivity, supporting both standard and custom SoC dis-aggregation protocols.
Overview
VeriFast BoW (Bunch of Wires) Verification IP is targeting ODSA protocol link layer adapter to Phy on BoW interface.
