Hi everbody, I´ve been asked in my company to advise for choosing among Protel and Electronics Workbench (I think is a compendium of packages that makes a whole suite). Anyway, I´ve used Protel before and I like it very much because it has a relatively simple interface. Also, it has a huge database of components and the editors are quite good (I love to be able to display the menus by pressing just a key). I also have used the simulator but only n Protel 99 because I couldn´t find the simulator in the in the DXP version. However, I´ve never used Electronics Workbench. I read the specs and highlights, and it seems to me that is very similar to Protel. I´ld try it myself, but I don´t have time right now to download the trial and install it. I also saw that this software has an RF module and other module for simulating communication systems. They make a comparison in their web site against Protel and Orcad, but I can´t rely on this comparison because it would only show the things that EW does better, but not the ones that Protel or Orcad is superior. So, the purpose of buying this software is for two things: first, for making analog simulations, specially at the transistor level by varying the manufacturing parameters; and second, to have it as an additional tool for PCB designs and maybe digital simulations. My request to the group is a recommendation among these two software packages, and also you may know of a better software than these two that has a better performance at a similar cost. Thanks to all, and sorry for sliding out a little of the group´s topic.
