Abstract

Transaction-level modeling (TLM) has been proposed as the leading strategy to address the always increasing complexity of digital systems. However, its introduction arouses a new challenge for designers and verification engineers, since there are no mature tools to automatically synthesize an RTL implementation from a transaction-level (TL) design, thus manual refinements are mandatory. In this context, the paper presents an incremental assertion-based verification (ABV) methodology to check the correctness of the TL-to-RTL refinement. The methodology relies on reusing assertions and already checked code, and it is guided by an assertion coverage metrics.
