How Important Is to Be Versed in the Use of Software Tools?

The speed of current technology advances could not be possible without  the extraordinary support provided by software for design, simulation, analyses, automated testing and manufacturing. Any professional or amateur in any Engineering, Technology, Science or any other activity must be versed in the use of some of the tools related to their area of interest. Despite of this need, some professionals devote so little for the acquisition, learning and use of these marvelous tools, something hard to understand when many are offered free and excellent. Do not limit your self for advance and progress, remember software can help  you to make a better job, faster, with less errors and most important more enjoyable.

What is CAD? = Computer Aided Design

What is CAM? = Computer Aided Manufacturing

Among others, the software types you can explore in this page are: microwaves software, radio frequency or RF design software, mechanical design software, pcb software, spectrum analysis software, mathematics software, analog design software, digital design software, mix mode software, pll simulation software, power supply design software, test software, spurious analysis software and more, from free to paid highly professional  suites, however most can be evaluated at no cost, some are free and excellent.  

 

The listing of the software is organized in engineering field tables, showing which one is offered as free and which only offer demos and trials only before purchasing their products
