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. 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.

But it also has its trade off as speedup is achieved on the cost of accuracy, especially in the presence of correlated signals.

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. Therefore, there has been a shift in the incline of the tool developers towards high-level analysis and optimization tools for power.

Motivation[ edit ] It is well known that more significant power reductions are possible if optimizations are made on levels of abstraction, like the architectural and algorithmic level, which are higher than the circuit or gate level [2] This provides the required motivation for the developers to focus on the development of new architectural level power analysis tools.

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 digitalcircuits using the VHDL hardware description language and synthesissoftware. Focusing on the module-level design, which is composed offunctional units, routing circuit, and storage, the bookillustrates the relationship between the VHDL constructs and theunderlying hardware components, and shows how to develop codes thatfaithfully reflect the module-level design and can be synthesizedinto efficient gate-level …mehr.
