Verilog Parameters

Understanding SystemVerilog module instantiation with parameters

This question tests whether you can correctly instantiate a parameterized SystemVerilog module. It requires familiarity with how parameter overrides work at the point of instantiation, and how to distinguish between default parameter values and those passed explicitly when creating module instances.

The skill matters in hardware design interviews because parameter reuse is fundamental to writing scalable, configurable RTL. Interviewers want to see that you understand the syntax for both positional and named parameter passing, and that you can read a module header and infer the correct instantiation semantics.

• Parameter declaration and scope
• Positional vs. named parameter override syntax
• Default values and their interaction with explicit overrides
• Port binding and parameter binding as distinct operations
