Satisfiability-based debugging of sequential and hierarchical designs.
Moayad Fahim Ali
Written in English
As VLSI designs grow in complexity and size, errors introduced during the design flow become more frequent, complex, and difficult to track. Debugging is the process of locating the source(s) of the error and applying corrections to rectify the design. Although much advancement has been made in the field of verification, debugging remains a manual and a resource-intensive step that consumes up to 60% of the design time and cost. This thesis proposes two novel debugging techniques, the first tackles flat gate-level sequential circuits, while the second handles hierarchical designs. The algorithms are based on Boolean Satisfiability (SAT) and Quantified Boolean Formula (QBF) Satisfiability, which are two fields that have experienced rapid development over the past few years due to their many applications in Electronic Design Automation (EDA). Experimental evaluation demonstrates that the proposed techniques are effective in reducing run-time and memory-requirements.

This page is from the beta release of the Data-Oriented Design book. There are errors, spelling and factual, and this page is only kept for purposes of maintaining old links. Data-Oriented Design. In programming, “Gotcha” is a well known term. A gotcha is a language feature, which, if misused, causes unexpected - and, in hardware design, potentially disastrous - behavior. The purpose of this book is to enable engineers to write better Verilog/SystemVerilog design and verification code, and to deliver digital designs to market more quickly.5/5(1).

An asynchronous circuit, or self-timed circuit, is a sequential digital logic circuit which is not governed by a clock circuit or global clock d it often uses signals that indicate completion of instructions and operations, specified by simple data transfer type of circuit is contrasted with synchronous circuits, in which changes to the signal values in the circuit.

Logic debugging of today's complex sequential circuits is an important problem. In this paper, a logic debugging methodology for multiple errors in sequential circuits with no state equivalence is. Formal Techniques in Design Debugging: Vennsa Technologies: Mandana Amiri: MEng () Satisfiability-based Debugging of Sequential and Hierarchical Designs: Intel Corp.
Sean Safarpour: MASc () Managing Don't Cares in Boolean Satisfiability. Over the years, the original SAT-based gate-level debugging formulation  has been extended to handle hierarchical RTL blocks , and its scalability and performance have improved.
As VLSI designs grow in complexity and size, errors become more frequent and difficult to track. Recent developments have automated most of the verification tasks but debugging still remains a. It has been reported that more than half of the total design effort was devoted to the verification and debugging process for a high-performance microprocessor design .
Automated Design Debugging With Maximum Satisfiability December IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems 29(11) - Test vector generation for counter- examples in sequential logic debugging is not the topic of this work .
Additionally, assuming that memory elements are fault-free allows both the speci cation and the netlist to reach a common initial state. For example. Debugging is a procedure in a design process that is started when the implementation of the design has failed verification.
The output of the verification engine is typically returned as a set of counterexamples CEs which proves the existence of a bug in the by: Design for Testability Analysis of Sequential Circuits. • Any sequential circuit can be divided into 3 classes of subcircuits based on the directed graph representation 1.
acyclic directed 2. directed with only self loops 3. directed with cycles of two or more vertices Ex: Size: KB. hierarchical hidden Markov models, the sequential model, unlike lstm doesn’t do long-term associations. it does local features but that’s actually what the brain is able to do so I wrote a book how to create a mind about the evidence we have from the neuroscience field and also from observing human brain in action as to why this why the Union human neocortex is organized this way.
example. A programmable controller (PC) programming technique using SFC (sequential function chart) has been adopted in sequential control system design because SFC can graphically represent the sequence flow of control logic. However, when we design an SFC program, we must verify the program with the design by: They also suggest that satisfiability captures significant characteristics of the problem of diagnosis and encourage novel research in satisfiability-based diagnosis as a complementary process to design by: Design and Analysis of Computer Algorithms (PDF P) This lecture note discusses the approaches to designing optimization algorithms, including dynamic programming and greedy algorithms, graph algorithms, minimum spanning trees, shortest paths, and network flows.
The book progresses from simple concepts such as sequential logic design to more complicated topics such as memory architecture and hierarchical sub-system design.
Later chapters bring together many of the earlier HLS design concepts through their application in simplified design by: A schematic view of debugging viewed as design. Such a model can be described as a reconstructive model, in which the programmer debugs through reconstructing some of the original design decisions and verifying them against the actual performance of the program.
This model is offered in contrast to the sequential comprehend and debug by: An OR gate's output is true if any input is a one. That is, it's zero only if every input is zero. The output of sequential logic reflects both the inputs and the previous state of the circuit.
That is, it remembers the past and incorporates history into the present. Abstract: Distributed applications written in Hermes typically consist of a large number of sequential processes.
The use of a hierarchy of process clusters can facilitate the debugging of such applications. Ideally, such a hierarchy should be derived by: FPGAs: World Class Designs 1st Edition. star rating functional unit in VHDL Basic variable types and operators Decisions and loops Hierarchical design Debugging models Basic data types Summary.

This section addresses the following important concepts in hierarchical decomposition: These concepts will be discussed with respect to the decomposition of a function into Author: Craig Borysowich.

In this paper, we study the use of QBF solvers for fault localization and correction of sequential circuits. Given a violated specification, we compute whether the circuit can be repaired by evaluating a sequence of quantified Boolean formulas. If a repair exists, it can be extracted from a certificate for another quantified Boolean by: Introduction and Overview Operating Systems Approach Used In The Text A Hierarchical Design The Xinu Operating System What An Operating System Is Not An Operating System Viewed From The Outside Remainder Of The Text Concurrent Execution And Operating System Services Programming Models For Multiple Activities Operating System Services Concurrent Processing Concepts And.
These sequential processes are placed at various hierarchical levels, in each of which one or more independent abstractions have been implemented. The hierarchical structure proved to be vital for the verification of the logical soundness of the design and the correctness of its implementation.
learn Verilog HDL. Verilog HDL allows different levels of abstraction to be mixed in the same model. Thus, a designer can define a hardware model in terms of switches, gates, RTL, or behavioral code.
Also, a designer needs to learn only one language for stimulus and hierarchical design. Most popular logic synthesis tools support Verilog HDL. Description.

Abstract. Parallel programs are much more difficult to develop, debug, maintain, and understand than their sequential counterparts.
One reason is the difficulty in establishing correctness - which must take into account temporal conditions: liveness, deadlock-freeness, process synchronization and communication, this is often called correctness : Xingfu Wu, Xingfu Wu.

In computer engineering, a hardware description language (HDL) is a specialized computer language used to describe the structure and behavior of electronic circuits, and most commonly, digital logic circuits. A hardware description language enables a precise, formal description of an electronic circuit that allows for the automated analysis and simulation of an electronic circuit.
