Remember Me? I know the basics of combinational logic and verilog, but i am not good at sequential circuit design state machines etc , I want to learn sequential circuits, advanced binary arthimatic fast adders etc and advanced verilog designs. Thanks in Advance! Rabaey is best book for Digital Design in my perspective.
For state machine design you can refer Digital design: principles and practices by John F. Goos]Integrated Circuit and System Design Part and Inventory Search. Welcome to EDABoard. Design Resources. New Posts. STM32 16bit wav player using Dac 2. Verilog Project Procedure App. Answers to Select Problems. Notes Includes bibliographical references and index.

Verilog HDL Background and History
Tags What are tags? Add a tag. Public Private login e. An HDL description can also be prototyped and tested in hardware — programmable logic devices are often used for this purpose. Hardware prototyping is comparatively more expensive than HDL simulation, but offers a real-world view of the design. Prototyping is the best way to check interfacing against other hardware devices and hardware prototypes.
Historically, design verification was a laborious, repetitive loop of writing and running simulation test cases against the design under test. As chip designs have grown larger and more complex, the task of design verification has grown to the point where it now dominates the schedule of a design team. Looking for ways to improve design productivity, the electronic design automation industry developed the Property Specification Language.

In formal verification terms, a property is a factual statement about the expected or assumed behavior of another object. Ideally, for a given HDL description, a property or properties can be proven true or false using formal mathematical methods.
In practical terms, many properties cannot be proven because they occupy an unbounded solution space. However, if provided a set of operating assumptions or constraints, a property checker can prove or disprove certain properties by narrowing the solution space. The assertions do not model circuit activity, but capture and document the designer's intent in the HDL code. In a simulation environment, the simulator evaluates all specified assertions, reporting the location and severity of any violations. In a synthesis environment, the synthesis tool usually operates with the policy of halting synthesis upon any violation.
Assertion based verification is still in its infancy, but is expected to become an integral part of the HDL design toolset. A HDL is grossly similar to a software programming language , but there are major differences.

Most programming languages are inherently procedural single-threaded , with limited syntactical and semantic support to handle concurrency. HDLs, on the other hand, resemble concurrent programming languages in their ability to model multiple parallel processes such as flip-flops and adders that automatically execute independently of one another.
Any change to the process's input automatically triggers an update in the simulator's process stack. Both programming languages and HDLs are processed by a compiler often called a synthesizer in the HDL case , but with different goals.

For HDLs, "compiling" refers to logic synthesis ; the process of transforming the HDL code listing into a physically realizable gate netlist. The netlist output can take any of many forms: a "simulation" netlist with gate-delay information, a "handoff" netlist for post-synthesis placement and routing on a semiconductor die, or a generic industry-standard Electronic Design Interchange Format EDIF for subsequent conversion to a JEDEC -format file.
On the other hand, a software compiler converts the source-code listing into a microprocessor -specific object code for execution on the target microprocessor. As HDLs and programming languages borrow concepts and features from each other, the boundary between them is becoming less distinct.

However, pure HDLs are unsuitable for general purpose application software development, [ why? Yet as electronic systems grow increasingly complex, and reconfigurable systems become increasingly common, there is growing desire in the industry for a single language that can perform some tasks of both hardware design and software programming.
SystemC is an example of such— embedded system hardware can be modeled as non-detailed architectural blocks black boxes with modeled signal inputs and output drivers. The high level of abstraction of SystemC models is well suited to early architecture exploration , as architectural modifications can be easily evaluated with little concern for signal-level implementation issues.
However, the threading model used in SystemC relies on shared memory , causing the language not to handle parallel execution or low-level models well. In their level of abstraction, HDLs have been compared to assembly languages. Annapolis Micro Systems , Inc.
