Design and Verification of Multi-clock Domain Synchronizers
Li Luo, Hongjun He, Qiang Dou, Weixia Xu · 2010
Clock domain crossing (CDC) is an important issue in integrated circuit (IC) design and verification. In this paper, We present the design of 5 types of CDC schemes in our developed SOC chip with multi working mode and ten clock domain, deeply describe an approach using assertion-based verification (ABV) to verify proper functionality for CDC signals. Taped sample chip tests show all CDC designs work right, and demonstrate that design and verification method are effective.
