Questions & Answers

Q: What are the different levels of abstraction in RTL design?

The different levels of abstraction in RTL design are transistor level design, logic level design, and register transfer level (RTL) design. Transistor level design involves building circuits and gates using transistors, logic level design involves designing circuits using logic gates, and RTL design involves designing processors and transferring data between registers and data path components.

Q: What is the first step in the RTL design process?

The first step in the RTL design process is capturing the behavior of the processor. This is done by using a high level state machine, which describes the system's behavior and includes multiple data inputs and outputs.

Q: How is the behavior captured in RTL design?

The behavior is captured by creating a high level state machine, which describes the system's behavior using states and transitions. Unlike a finite state machine, which uses single bit inputs and outputs, the high level state machine in RTL design uses multiple bit inputs and outputs.

Q: What is the purpose of the data path in RTL design?

The data path in RTL design is used to carry out the data operations specified in the high level state machine. It includes components such as adders, which perform the necessary operations based on the behavior captured in the state machine.
