How to Differentiate Between `logic` and `wire` Data Types in SystemVerilog
When working with SystemVerilog, it is essential to understand the differences between the `logic` and `wire` data types.
Focus Keyword: Differentiating Between `logic` and `wire` Data Types
1. `logic` Data Type:
The `logic` data type is a 4-state type that allows for all possible logic values - 0, 1, X (unknown), Z (high-impedance).
2. `wire` Data Type:
The `wire` data type is used to represent interconnect wires in a hardware design. It is a 4-state type that can have values of 0, 1, X (unknown), or Z (high-impedance).
One key difference between `logic` and `wire` is that while `logic` is primarily used within procedural code to represent signal types, `wire` is used to connect signals between hardware modules.
Understanding the nuanced differences between these data types is crucial for developing effective SystemVerilog designs.
