How do you assign a value in wire Verilog?

Wire is used as combinational logic. You can assign it, e.g. assign a = 1'b1. In this case, the one which holds the value is 1'b1. Reg can be used as either combinational or sequential logic.

What is the use of Verilog HDL?

You can use Verilog HDL for designing hardware and for creating test entities to verify the behavior of a piece of hardware. Verilog HDL is used as an entry format by a variety of EDA tools, including synthesis tools such as Quartus® Prime Integrated Synthesis, simulation tools, and formal verification tools.

What is SystemVerilog used for?

SystemVerilog, standardized as IEEE 1800, is a hardware description and hardware verification language used to model, design, simulate, test and implement electronic systems.

How do I assign a register in Verilog?

In the below Verilog assignment register rotationDoneR is assigned to the Signal and then the other register rotationDoneRR is assigned to the same register. Doesn't that mean that both registers hold the same value and the condition is never true?
