While today’s RTL design and verification flows are a step up from the gate-level flows of two decades ago, RTL flows are straining to meet the demands of most product teams. With increasing pressure on today’s SoC and ASIC design teams to deliver more aggressive designs in less time, and the need to get designs right on the first pass, many companies are looking to move to the next level of abstraction beyond RTL to get a much-needed boost in design productivity. This paper describes the key challenges that demand a change from RTL as the entry point for design and verification IP. It outlines the TLM-driven solution that’s needed and cites its advantages. Finally, the paper provides some information about the Cadence TLM solution.
