| Abstract |
| |
| Multiple, independent clocks have become a fact of life on SoCs and other complex ASICs. In extreme cases, such as in large communications processors, clock domains may number in the thousands. Clock domain crossings pose a growing challenge to chip designers...

| Verification of Multi-Clock Designs |
| |
| Abstract |
| |
| This white paper outlines a holistic approach to resolving issues associated with ever increasing numbers of clock interfaces, where data is transferred between clocks of different frequencies and often between asynchronous domains. The paper suggests exercising various technologies as part of an intuitive user environment, and highlights why addressing one issue in isolation can at best jeopardize timing closure, and at worst introduce silicon risk. |
