Open Source C++ Design Software

XLS is an open-source toolkit for building high-level hardware with a modern compiler stack that spans from a functional DSL to optimized IR and hardware generation. At the front end, DSLX lets you describe algorithms with strong typing and familiar control flow while remaining synthesis-friendly. The compiler lowers DSLX into a rich intermediate representation, applies aggressive optimization and scheduling passes, and can either JIT the design for software simulation or emit Verilog for FPGA/ASIC flows. A key idea is “software-style” iteration: fast, deterministic simulation via the JIT encourages test-driven development and property checking before committing to RTL. XLS also provides tooling for pipelining, state insertion, and formal equivalence checks between different stages, giving developers confidence as designs evolve. The result is a productive path from high-level specification to real hardware, without giving up control over latency, throughput, and area trade-offs.

A graphical tool for designing finite state machines and exporting them to Hardware Description Languages, such as VHDL, AHDL, Verilog, or Ragel/SMC files for C, C++, Objective-C, Java, Python, PHP, Perl, Lua code generation.

A C++ library of designs, containing flexible implementations of common design patterns and idioms.

ConceptBase.cc is a multi-user deductive and object-oriented database system for metamodeling and method engineering. Includes a graphical client that builds upon the logic-based features of the ConceptBase.cc server. The data model is O-Telos. ConceptBase.cc can represent information at the data level (example data, traces of process executions etc.), the class level (schemas, process definitions etc.), the metaclass level (constructs of modeling languages), the meta-metaclass level (constructs for defining modeling languages), and so forth. ConceptBase.cc is developed by the ConceptBase Team at University of Skövde (HIS). ConceptBase.cc supports Linux, Mac OS X and Windows. ConceptBase.cc is free software distributed under a FreeBSD-style license.

Provides: WYSIWYG editing fully integrated into Word; Typechecking using fuzz (for Spivey Z) or CZT (for ISO standard Z); Indexing and cross-referencing; Diagrams of specification structure; Conversion from Spivey to Standard Z- also available as a stand-alone program and Java class for non-windows users. See project website for details.

TTFviewer is a small tool for developers to view and preview various ttf font/icon image formats. It is based on Qt and supports windows/linux/macos.

Commodore Basic and text editor. It can edit Commodore Basic PRG, text, asm, d64, data files. Basic tools - Find text - Goto, Renumber , Insert Characters - D64 manipulation, load save rename - Decimal to Hex, assembly frontend.

HiPS tool is developed at the Department of Computer Science and Engineering, Shinshu University, which is a tool design and analysis of Petri nets, developed using Microsoft Visual C # and C++. HiPS tool has a way of intuitive GUI which enable hierarchical and/or timed-net design. HiPS tool has also functions of static/dynamic analysis : T-invariant detection, Reachability path analysis, deadlock state detection, and k-boundedness analysis. In addition, it is possible to perform a random walk simulation with each firing steps.

With the help of the ProgramNet the user can develop plug-ins(called units) which can be connected with other units forming a net. The net has a form of a flow diagram. The resulted net can be executed in the ProgramNet for testing purposes or independently in the target platform as a final release. In order to execute a net the ProgramNet uses the kernel. The kernel executes automatically each unit in a separate thread and manages the data exchange between the units.

ClassBuilder is freeware CASE tool targeted at the C++ developer, running on Win2K/XP/Vista/7. It lets you create, manipulate and navigate classes, class relations, class members and class methods at a high level of abstraction through a graphical user interface

Duplicated source code can harm maintainability of software systems. Duplo is a tool to find duplicated code blocks in large C, C++, Java, C# and VB.Net systems.

When computer power increases, programmers generally add more "features", thus making any performance gains in new hardware negligible. This project is an attempt to develop a library above libc that breaks out of this terrible loop.

OnyX is a C++ Integrated Development Environment for Linux that resembles the old Visual basic 3.0

123SQL engine is a small portable relational database aimed for PDAs. Data is inserted via database import of spredsheet TAB delimited column data. Browsing is performed via SQL syntax commands.(http://www.jasenko.com.mk)

Almas Designer is a dialog editor for wxWidgets. It's a sizer based RAD tool for wxWidgets with code generation which allows you to develop wxWidgets programs more easily.

This is a tool developed by 2nd yr CSE B.Techs at IIT Guwahati.We have designed a software in C++ language which,given some design specifications of an analog amplifier generates a netlist file in the current folder which can be opened in LTSpice.

The Basic Object System (BOS) means to provide a dynamic environment for hosting and using components. It can also be described as a general purpose software framework based on component technology.

C++ SimpleTable is a class which enables the developer to create tables and detect design errors in compile-time

Catsfoot provides to C++ concept checking, overloading with concepts and concept testing to C++ 2011 as a library.

Code Appearance is a small application that beautify the code before you put it on a forum or a website. What it does? It adds color to the code, like the syntax highlighting of your favorite IDE. The syntax files are easily customizable. How it works? You choose a syntax file, these files can be downloaded or made by you, and write/copy/open your code and click on execute. A new window will pop up with the result. On this new window, you will be able to save or copy the code to the clipboard.

Code generator based on wxWidgets

Javascript animation authoring environment. A WYSIWYG cross-platform desktop application using jQuery to animate XHTML and HTML elements. Its built in XUL.

An algorithm to efficiently compute the number of products and the commonality of the features modeled by a Feature Diagram

The API features a layer between the trivial PHP and the low level web GUI (XHTML, XML, Javascript, PDF, Ajax ...). It’s extensible because of its clean and easy structure. The Concept comes with a widget toolkit, many plug-ins, themes and sub-modules.

**** THIS LIBRARY WAS MOVED INTO Boost **** New location: https://github.com/boostorg/contract C++ Contract Programming (a.k.a. Design by Contract or DbC). All Eiffel features supported: subcontracting, postcondition old and result values, optional contract compilation, customizable action on assertion failure, block invariants, loop variants, etc. Plus virtual specifiers, concept checking, named parameters.
