Below are some language specific questions on System Verilog:

​

1. What are the different types of procedural blocks in SystemVerilog, and how do they differ in terms of execution and event sensitivity?
2. Explain the differences between static arrays and dynamic arrays in SystemVerilog.
3. How do you handle clock domain crossing (CDC) issues in SystemVerilog? Describe some techniques or methodologies you have used.
4. What are the differences between continuous assignments and procedural assignments in System Verilog?
5. Explain the purpose and usage of the "disable" statement in System Verilog.
6. How does System Verilog support assertion-based verification (ABV)? Describe the key constructs and methodologies used for ABV.
7. Describe the role and usage of the "bind" directive in System Verilog.
8. How do you handle complex bus protocols (e.g., AXI, PCIe) in System Verilog? Explain the concept of layered and structured verification environments.
9. What are virtual interfaces in System Verilog, and how are they used in verification?
10. Explain the concept of transaction-level modeling (TLM) and how it can be implemented in System Verilog.
11. Discuss the differences between immediate assertions and concurrent assertions in System Verilog.
12. How do you handle functional coverage and code coverage analysis in System Verilog? Describe the methodologies and tools you have used.
13. Explain the concept of assertions and assume-guarantee modeling in System Verilog.
14. Describe the concept of randomization and how it is implemented in System Verilog for stimulus generation in verification.
15. Discuss your experience with using DPI (Direct Programming Interface) in System Verilog and its advantages for integrating System Verilog with other programming languages.

These questions delve deeper into various aspects of the System Verilog language and its application in verification. They cover topics such as procedural blocks, arrays, clock domain crossing, assertions, interfaces, coverage analysis, DPI, and more. Assessing the candidate's knowledge in these areas will help gauge their expertise and proficiency in System Verilog.
