Flows and methodology. In ASIC projects, a host of rules and caveats play an inhibiting role in the application of best-known tools and practices in favor of the “tried-and-true” methods that have years of service.COT design flows permit designer intervention at every stage in the process, without a huge time penalty. In an ASIC flow, data must be passed between organizations and each party performs the intervention for their part of the design flow for example, RTL fixes are done by the design team; antenna rule violations are fixed by the ASIC vendor. This limits the timing and the nature of intervention options available to the design team. The COT flow is used to get and maintain full control over all options, and has shown to deliver the highest performance with smallest die size and power. By NeuSemi 02.18.2025 By Telink Semiconductor 02.18.2025 By Chip-GaN Power Semiconductor Corp. 02.13.2025 Typical estimates are that COT data pathways have 30% to 50% faster performance and the die size is 25% to 50% smaller when using a COT flow versus a traditional ASIC flow. These numbers are really the bottom line in the COT versus ASIC decision. Chip performance equals product value, and chip size equals product cost in the router market. However, one should be aware that there is a large, incremental cost associated with COT flows. COT requires more tools, and more designers to run these tools. Full-blown, backend design capabilities cost $1 million or more per seat. Experienced engineers
