Coding for Efficiency, Portability, and Scalability Author s: Pong P. First published: Print ISBN: All rights reserved. About this book The skills and guidance needed to master RTL hardware design This book teaches readers how to systematically design efficient, portable, and scalable Register Transfer Level RTL digital circuits using the VHDL hardware description language and synthesis software.
Focusing on the module-level design, which is composed of functional units, routing circuit, and storage, the book illustrates the relationship between the VHDL constructs and the underlying hardware components, and shows how to develop codes that faithfully reflect the module-level design and can be synthesized into efficient gate-level implementation.
Several unique features distinguish the book: Readers learn good design practices and guidelines to ensure that an RTL design can accommodate future simulation, verification, and testing needs, and can be easily incorporated into a larger system or reused.
With a balanced presentation of fundamentals and practical examples, this is an excellent textbook for upper-level undergraduate or graduate courses in advanced digital logic.

Engineers who need to make effective use of today's synthesis software and FPGA devices should also refer to this book. He has received grants from both NASA and the National Science Foundation, and has taught undergraduate and graduate-level digital systems and computer architecture courses for more than a decade.

Summary PDF Request permissions. Registers usually implemented as D flip-flops synchronize the circuit's operation to the edges of the clock signal, and are the only elements in the circuit that have memory properties.
Combinational logic performs all the logical functions in the circuit and it typically consists of logic gates. For example, a very simple synchronous circuit is shown in the figure.
The inverter is connected from the output, Q, of a register to the register's input, D, to create a circuit that changes its state on each rising edge of the clock, clk. In this circuit, the combinational logic consists of the inverter.
When designing digital integrated circuits with a hardware description language , the designs are usually engineered at a higher level of abstraction than transistor level logic families or logic gate level. In HDLs the designer declares the registers which roughly correspond to variables in computer programming languages , and describes the combinational logic by using constructs that are familiar from programming languages such as if-then-else and arithmetic operations.
This level is called register-transfer level.
The term refers to the fact that RTL focuses on describing the flow of signals between registers. The synthesis tool also performs logic optimization.
At the register-transfer level, some types of circuits can be recognized. If there is a cyclic path of logic from a register's output to its input or from a set of registers outputs to its inputs , the circuit is called a state machine or can be said to be sequential logic.
RTL Design, Synthesis and Implementation
If there are logic paths from a register to another without a cycle, it is called a pipeline. RTL in the circuit design cycle[ edit ] RTL is used in the logic design phase of the integrated circuit design cycle.
An RTL description is usually converted to a gate-level description of the circuit by a logic synthesis tool. The synthesis results are then used by placement and routing tools to create a physical layout.
Logic simulation tools may use a design's RTL description to verify its correctness.

Power estimation techniques for RTL[ edit ] The most accurate power analysis tools are available for the circuit level but unfortunately, even with switch- rather than device-level modelling, tools at the circuit level have disadvantages like they are either too slow or require too much memory thus inhibiting large chip handling. The majority of these are simulators like SPICE and have been used by the designers for many years as performance analysis tools.
Due to these disadvantages, gate-level power estimation tools have begun to gain some acceptance where faster, probabilistic techniques have begun to gain a foothold.Print ISBN: Power estimation techniques for RTL[ edit ] The most accurate power analysis tools are available for the circuit level but unfortunately, even with switch- rather than device-level modelling, tools at the circuit level have disadvantages like they are either too slow or require too much memory thus inhibiting large chip handling.
Therefore, there has been a shift in the incline of the tool developers towards high-level analysis and optimization tools for power. Register Transfer Methodology: Jetzt verschenken.
Suggests additional modules and peripherals for interesting and challenging projects. Over the years it has been realized that biggest wins in low power design cannot come from circuit- and gate-level optimizations whereas architecture, system, and algorithm optimizations tend to have the largest impact on power consumption.
The inverter forms the combinational logic in this circuit, and the register holds the state. Focusing on the module-level design, which is composed of functional units, routing circuit, and storage, the book illustrates the relationship between the VHDL constructs and the underlying hardware components, and shows how to develop codes that faithfully reflect the module-level design and can be synthesized into efficient gate-level implementation.
Gate Equivalents  [ edit ] It is a technique based on the concept of gate equivalents.
