A circuit simulator with graphical user interface (GUI)
Qucs is a circuit simulator with graphical user interface. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Transient, Noise and Harmonic Balance analysis. Pure digital simulations are also supported.
Simple and intuitive 2D vector drawing for electronics and not only.
A multiplatform vector drawing program with a complete library of electronic symbols. Schematics and drawings are stored in a very compact text format. There is no netlist concept behind the drawings (so no simulation, and this is a choice) but this allows a great graphical flexibility and ease of use, making FidoCadJ the perfect tool for exchange sketches in forum and newsgroup discussions with a few clicks. Drawings can be exported in several graphic formats, such as pdf. Follow the development live on Twitter: https://twitter.com/davbucci
TkGate is a event driven digital circuit simulator with a tcl/tk-based graphical editor. TkGate supports a wide range of primitive circuit elements as well as user-defined modules for hierarchical design.
upf2cpf is a cool command line tool which will takes in a UPF(Unified Power Format) and will convert it to a CPF(Common Power Format).This tool is very useful for Chip Design Engineers, who want to feed the power related info about the RTL in UPF/CPF.
Make your own virtual FPGA system and profile deeply with CI.
TestDrive Profiling Master is a free simulation software for Verilog/SystemVerilog and C/C++. It supports a CI (Continuous Integration) activity for H/W & S/W engineers' cooperation. Run by MS Windows environment, its use is governed by MIT License(Profiles) and LGPLv3(TestDrive Profiling Master). Based on the powerful compiler Verilator and GCC, TestDrive Profiling Master provides a totally free virtual FPGA system environment with various dynamic documents for profiling in deep on your system design. It performs a seamless conversion to a real FPGA environment without any changes of your testing software. I hope you will accomplish a successful design with TestDrive Profiling Master.
