KiCad is an open-source electronics CAD tool. You can create schematics and design PCBs using an extensive open source library of parts. View your resulting PCBs in 3D and export to gerbers for manufacturing.

wasora is a computational tool designed to aid a cognizant expert, whether an engineer, scientist, technician, or geek, to analyze complex systems by solving mathematical problems by means of a high-level plain-text input file containing algebraic expressions, data for function interpolation, differential equations, and output instructions amongst other facilities. At first glance, it may look like another high-level interpreted programming language, but it should be seen as a syntactically-sweetened way to ask a computer to perform a certain mathematical calculation. For example, the famous Lorenz system may be solved by writing the three differential equations in a human friendly plain text file.

fxopt is a plugin for GCC that converts floating-point functions to fixed-point arithmetic, primarily for implementation in embedded, real-time systems without floating-point hardware. The conversion is performed in GCC's "middle-end", after the source code has been converted to GCC's intermediate representation but before any target-specific optimizations are done. Several optimization options are available to improve the accuracy of the fixed-point arithmetic, including affine range estimation, rounding, and double-precision multiplications. Fixed-point code produced by fxopt can be significantly more accurate than typical fixed-point implementations with comparable execution time and code size. In many cases the fixed-point code produced by fxopt provides accuracy comparable to single-precision floating-point arithmetic with a factor of 10 faster execution.

Cuadro CPU Benchmark measures the CPU performance by numerically finding a solution and measuring the runtime of the two-dimensional heat equation in Cartesian coordinates. The program is a model of a vertical square stainless steel plate undergoing heat generation and natural convection on both sides. It finds a temperature distribution matrix of this system at every time step.
