FlexRay VIP

FlexRay Verification IP provides an smart way to verify the FlexRay component of a SOC or a ASIC. The SmartDV's FlexRay Verification IP is fully compliant with standard FlexRay 2.1 (plus addendum) Specification and supports all the frame types such as Static and Dynamic frames.Also supportes all operating modes such as STANDBY,NOCE,STARTUPFRAMECAS,STARTUPFRAME and SINGLESLOT modes.

Flexray 2.1 VIP includes an extensive test suite covering most of the possible scenarios. It can perform all protocal tests and moreover it allows an easy generation of very high number of patterns and a set of specified patterns to stress the DUT.

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