Achieving CDC Signoff On Multi Billion Gate Designs With Hierarchical CDC Flow


For the last few decades, the System-on-Chip (SoC) design size has dramatically increased and more complexity has been introduced to deliver the desired functionality. A typical SoC can have many complex IPs operating at different clock frequencies, which can stress the verification cycle. Generally, design and verification teams are spending an increasing amount of time to ensure that the SoC ... » read more

Eliminate Silicon Respins With Netlist CDC Verification


Clock domain crossing (CDC) verification has been an integral part of modern chip design flow for quite sometime. Traditionally CDC verification has been done during the RTL stage. However, for advanced designs and complex flows, there is significant logic optimization during RTL synthesis as well as backend flows at the netlist stage. This mandates clock domain crossing verification a must for... » read more

Constraint-Based Verification Of Clock Domain Crossings


There are many measures of the ever-growing size and complexity of semiconductor devices: die area, transistor count, gate count, size of memories, amount of parallel processing and more. All these factors mean more time spent in design, but they also have a major impact on verification. Since virtually all industry studies show verification time and effort growing faster than design, this impa... » read more

Finding CDC Issues Before They Find You


Clock domain crossings (CDCs) in FPGAs represent a probabilistic opportunity for failure. Functional simulation and static timing analysis tools are insufficient. Finding and addressing metastability and data incoherence around CDCs require static and dynamic analysis of FPGA designs. Aldec ALINT-PRO-CDC provides enhanced confidence that CDCs are located and fully mitigated. To read more, cl... » read more
