Verilog Concatenation and Replication

SystemVerilog concatenation and replication syntax

This is a beginner-level SystemVerilog question that tests your command of bit-level operations and vector construction. It probes whether you can combine concatenation and replication operators to build a larger word from smaller pieces—a common pattern in digital design and RTL coding.

The question requires you to understand how SystemVerilog's concatenation operator (which joins signals side-by-side) and replication operator (which duplicates a signal a specified number of times) work together. Getting the syntax and operator precedence right is essential for writing clean, readable HDL code that synthesizes correctly.

• Concatenation operator syntax and bit ordering
• Replication operator and count specification
• Operator precedence and nesting
• Vector bit indexing and grouping
