Bartels AutoEngineer is a commercial CAD tool for electrical / computer engineers. It supports Linux, Win95/NT, DOS, OS/2, HP, DEC and Sun. Features include a schematic Editor with hierarchical design support, Forward/Backward Annotation, PCB Layout system, CAM Processor, CAM View, Integrated, object-oriented database system, User Language Compiler, utility programs for database management, foreign net list and design data import, etc. and part libraries for SCM and PCB layout
BitGen accepts text strings of 1's, 0's and hex digits and converts them to equivalent "pwl" voltage sources for inclusion in netlists for circuit simulation (with SPICE or Spectre, for example). Periodic waveforms (eg, clocks) can be exported as "pulse" voltage sources. Parameters such as rise time, fall time, pulse width and duty cycle can be set on a waveform-by-waveform basis. BitGen is written in Perl with the Perl/Tk toolkit and has an easy-to-use graphical interface.
The Eagle EDA software is composed of tightly integrated modules for PCB design, including Schematic Capture, Board Layout, and Autorouter. There is a free full-function (only board size limited) non-commercial license available for hobby and educational use as well. Windows, DOS, and of course, Linux versions are available.
gEDA is a suite of electronic design automation (EDA) tools. Currently, the project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.
HDLmaker generates hierarchical Verilog and VHDL code, PCB netlists, simulation and synthesis scripts/projects/make files, and schematics. It can translate Verilog/VHDL and HDLmaker projects into HTML, including extensive hyperlinking between the modules. It can also translate PADS PCB netlists into Verilog and VHDL and can do some simple VHDL to Verilog translations. HDLMaker synplifies the development of complex FPGAs and ASICs, and has extensive support for most Xilinx FPGAs.
LinkCAD is an all-in-one converter for AutoCAD DXF, Gerber RS274X, Calma GDS-II, CIF, PostScript, IE3D, TLC, and more. LinkCAD allows you to convert your mask or PCB layout between all the supported formats. Typical users are layout designers in the electronics industry, and mask designers for micro-technology applications.
