WAVES is the Industry standard representation and exchange format for digital stimulus and response data. The WAVES standard provides a powerful support mechanism for concurrent engineering practices by allowing digital stimulus and response information to be freely exchanged between multiple simulation and test platforms. WAVES is defined as a syntactic subset of the VHSIC Hardware Description Language ( VHDL), and as such, can be simulated against the VHDL model during design to verify the functionality and timing of the design as it progresses. Further, when devices are fabricated the same WAVES data can be ported to the electrical test process to assure that the same vectors and timing that were used during design are applied during test.
