The chapter key highlights are the detail description for the synchronizers, data path, and control path synchronization logic using the efficient Verilog RTL. This chapter focuses in the key design techniques which are used to describe the multiple clock domain designs while passing data from one of the clock domain to other. These kinds of designs need to be described using the efficient design architectures and Verilog RTL. It shows how the design rule checks and features in Vivado help automate this flow for the user. Hence, it has been proven effective and highly successful in increasing the TDF test frequency to the highest operating clock domain frequency of the design.In the practical ASIC and SOC designs the multiple clocks are used and the designs are called as multiple clock domain designs. This video shows how a design with multiple clock domains can be assembled using Vivado IP Integrator. In an experimental 200 M-transistor and 4-clock-domains test-chip netlist, this methodology is able to identify clock sources for all registers in five minutes time, and that processing time is negligible when compared to the TDF automatic test pattern generation (ATPG) time. It identifies all user registers in the design and recursively identifies the clock sources of those registers through intelligent net connectivity analysis. The methodology advocated in this paper aims to overcome this bottleneck by introducing an automated yet comprehensive approach to segregate and consolidate the various clock domains in any design for more effective TDF testing. Despite transition delay fault (TDF) tests providing reasonable coverage against DSM marginal defects, this methodology is hampered in designs with multiple clock domains where the lowest operating clock frequency becomes the dominant TDF testing frequency. With the rapid advancement of fab process technology into the nanometer node era, there is an increasing trend in the manifestation of deep submicron (DSM) marginal defects in integrated circuit (IC) fabrication. © Springer Science+Business Media, LLC 2009.
