RapidIO Verification IP provides an smart way to verify the RapidIO bi-directional two-wire bus. The SmartDV's RapidIO Verification IP is compliant with RapidIO Trade Association, RapidIO Interconnect Specification version 1.3 and 2.1. RapidIO VIP is implemented in a layered fashion. Whichis basically divided into a physical layer, transport layer and logical layer. The SmartDV's RapidIO Verification IP has both the incarnations of RapidIO technology :Parallel RapidIO and Serial RapidIO(SRIO).

The RapidIO VIP monitor acts as powerful protocol-checker, fully compliant with RapidIO specification. The RapidIO VIP includes an extensive test suite covering most of the possible scenarios. It performs all possible protocol tests in a directed or a highly randomized fashion which adds the possibility to create most wide range of scenarios to verify the DUT effectively.

RapidIO VIP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
