The growing complexity of chip design is creating new challenges for engineers, particularly when it comes to managing data traffic between different parts of a chip. As chips become more complex, they are being broken down into smaller components called chiplets.
Designers are struggling to validate the performance of Networks-on-Chip (NoCs) that connect multiple chiplets. NoCs are critical for managing data transfer between different parts of a chip.
Defining all possible cases of coherent and non-coherent traffic is a complex task. Designers need to use a combination of hardware-assisted verification and simulation tools to validate NoC performance. However, simulating NoCs that connect multiple dies is challenging due to the large number of interconnects and multiphysics issues involving thermal and crosstalk effects.
As the number of chiplets increases, so does the complexity of the NoC. Engineers must consider factors such as congestion, thermal effects, and signal integrity when designing NoCs. This requires advanced simulation tools that can model the behavior of the NoC under various scenarios.
The increasing complexity of NoCs is putting pressure on simulation tools to keep up. Designers need tools that can handle large, complex designs and provide accurate results quickly. If simulation tools cannot keep up, it could lead to delays in chip development and potentially even chip failures.
The consequences of failing to manage NoC complexity could be significant. Delays in chip development could give competitors an edge, while chip failures could lead to costly recalls and damage to a company's reputation.
