suresh What is the difference between `=` and `<=` in SystemVerilog?
In SystemVerilog, the `=` and `<=` operators are used for different purposes in hardware description and assignments. The main difference between the two is in how they are used and the behavior they exhibit.
The `=` operator is used for procedural assignments and is generally found within procedural blocks such as always or initial blocks. It assigns the value on the right-hand side to the variable on the left-hand side at the current simulation time. This operator is typically used for sequential logic where the assignment happens immediately.
On the other hand, the `<=` operator is used for continuous assignments and is commonly used in conjunction with combinational logic. It assigns the value on the right-hand side to the variable on the left-hand side continuously without considering the current simulation time. This operator is typically used for concurrent assignments where the assignment is made continuously based on the input changes.
Therefore, the key difference between `=` and `<=` in SystemVerilog lies in their usage for procedural and continuous assignments, respectively.
