Open Source C++ Design Software

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

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.

Fluid is a collection of cross-platform QtQuick components for building fluid and dynamic applications, using the Material Design guidelines. Online documentation is available at docs.liri.io. We develop using the git flow method this means that the develop branch contains code that is being developed and might break from time to time. If you want to check out a stable version just install one of the releases or clone the master branch that has the latest released version.

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.

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.

Version 8.2.14.26.09 RC [2017-2026] - Fully ported library. September 27, 2026. This project presents a clone 100% of the Borland Turbo C/C++ or Embarcadero C++ library "conio" (https://l1nq.com/tOsMbeb) for the GCC/Clang compiler, more precisely for the C++ language in Windows, Linux, and Mac OS operating systems. Because all functions are defined within the header file itself, the installation is simple. Just place the header file "conio_am.h" (CONsole Input Output Advanced Method) inside the GCC includes directory. Or keep the file "conio_am.h" in the same location where the source programs will be compiled. For more libraries, go to https://sourceforge.net/u/augustomanzano/profile.

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.

The KlassModeler is a cross platform tool for visually creating C++ classes and class relationships. It generates attractive header files as well as HTML Documentation. An intuitive user interface makes it easy to work with large, complex models.

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.

Louvre is a high-performance C++ library designed for building Wayland compositors with a strong emphasis on ease of development. It provides a default way for managing protocols, enabling you to have a basic but functional compositor from day one and progressively explore and customize its functionality to precisely match your requirements. Within Louvre, you have the flexibility to either employ your own OpenGL ES 2.0 shaders/programs, use the LPainter class for fundamental 2D rendering, or leverage the LScene and LView system, which manages buffer damage and can also handle input events for you. Additionally, it's possible to combine these three approaches as needed.

PapaFactory is a header-only C++ library providing three generic abstract factories. The library is licensed under the Boost software license which allows incorporation into propriety software.

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.

Tools to allow Z specifications to be written in Microsoft Word. Includes a unicode font for Z symbols. 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.

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.

This software should help to easy migrate Delphi forms (Delphi & CBuilder) into Qt4 forms. The converter itself is written in Qt4.x. Special Thanks to Robert.

FireGUI is a cross platform gui design tool.write by wxWidgets lib. generate code with wxWidgets,MFC,fox,and so on.

Head First Design Patterns translated to C++. Three separate translations are planned: 'Bronze' is literal; minimal (syntax) changes only. 'Silver' is semantic; more C++ idioms + leftover patterns. 'Gold' is (forthcoming and) modern; template based

QBlock is a cross-platform rapid-prototyping game design engine written in C++, SDL and OpenGL. Features game asset management, scrolling tilemaps, particle systems, 3D model support, Lua scripting and more.

Converts wxWidgets C++ code components (generated by wxDev-C++) to XML code. Allows users to port wxFrames created with the wxDev-C++ visual designer RAD to other IDEs.

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.
