CONTANGO: Integrated Optimization of SoC Clock Networks

Table 4

The “Full flow” column shows skew change at each step in the Contango flow, and the final skew. Acronyms are decoded in the caption of Table 3. Subsequent columns show the impact of removing one optimization. These results illustrate the range of each optimization and its impact on final results.
