Abstract

Since the early 80’s, when first high-level synthesis (HLS) algorithms appeared, behavioral synthesis tools have had to evolve quickly. From day to day new fields of application are being discovered that require to review the old techniques. Continuously, the market is requiring new algorithms able to perform more efficient search of solutions. Everyday more abstract specification methods are required, which enlarge the semantic gap between specification and circuit. And all this development has got a price to be paid: the complexity of algorithms grows and the supporting data structures become more sophisticated. As a consequence, the bugs in the tools (or even in the algorithms) proliferate. The effect is that reliance in synthesis tools decreases and nowadays no sensible designer takes the risk to accept a circuit automatically generated without a later validation step; either using simulation or verification techniques. This means, in practice, that the well-known paradigm of correctness by construction, widely publicized formerly, has to be handled very carefully.
