Abstract:

As FPGA designs grow in size and complexity, the challenge of Clock Domain Crossing (CDC) verification becomes increasingly critical. Improper handling of asynchronous clock boundaries can lead to metastability, glitches, and loss of data coherency—causing unpredictable functional behavior in hardware.

While AMD (Xilinx) Vivado Design Suite includes built-in CDC checks, its capabilities may be insufficient for complex, multi-asynchronous clock designs. Vivado's CDC reporting provides valuable insights, including Xilinx-specific checks such as the ASYNC_REG attribute, but lacks the depth of specialized CDC verification tools like ALINT-PRO.

In this webinar, we will compare Vivado’s built-in CDC verification with the advanced capabilities of ALINT-PRO. Using real-world design examples, we will highlight CDC issues that Vivado may miss and demonstrate how ALINT-PRO enhances CDC analysis and debugging. Finally, we will showcase a case study on Ethernet MAC CDC verification, featuring multiple asynchronous clock domains.

Agenda:

Overview of CDC Verification in AMD Vivado and ALINT-PRO
Comparing CDC Checks & Debugging Features in Both Tools
Real-World Examples: CDC Issues Missed by Vivado
Ethernet MAC Case Study: CDC Verification Across Three Asynchronous Clock Domains
Key Takeaways & Q&A

Join us to learn how advanced linting can streamline your design process, reduce debugging time, and improve overall design reliability.
