The Serial RapidIO (SRIO) Gen 2.2 protocol is an energy-efficient and high-performance interconnect protocol designed specifically for high-speed embedded applications and is well suited as a system-level fabric. SRIO Gen 2.2 standard protocol has defined many useful features organized under LOGICAL, TRANSPORT and PHYSICAL layer specifications.

This paper aims to help the engineers involved in the Serial RapidIO (SRIO) Gen 2.2 standard interconnect based product design or verification to realize buffer management and maintenance rules defined by the SRIO standard specification. Simple examples and explanations are provided throughout this document to describe how buffer management and maintenance mechanism is performed within the SRIO architecture. Understanding SRIO standard features will help verification engineers in quickly detecting issues in the design at an early stage of verification.
