A few of the listed packages I have experience with, for some others I know designers with extensive experience. So some of my comments may be of use. > OrCAD, Inc > Software: OrCAD Capture CIS (Release 9) > OrCAD Layout Plus (Release 9) As others have said, Capture is good. Layout, if someone held a gun to my head and told me I had to design with it, I'd hesitate, like Bob Hope when a robber stuck a gun in his ribs: "Your money or your life." For those of you who never saw this, Hope hesitated. The robber again repeated it, and Hope answered "I'm thinking, I'm thinking!" > Zuken-Redac Inc. > Software: Cadstar I was recently being interviewed by a company and was told that this company was the largest Cadstar user in the United States. I don't know that this was true. They were not particularly happy with it and were considering moving to Allegro. > VeriBest, Inc. > Software: Ascent L2 > > Company: Cadence > Software: Allegro Studio > > ACCEL Technologies, Inc > Software: Accel EDA > > PADS Software, Inc. > Software: PADS Power PCB > > Mentor Graphics Corporation > Software: Board Station There are vast differences in price between some of these and others. All of these have reasonably good reputations. And with high initial prices go higher maintenance costs. But, since OrCAD was on the list, I think that Protel should also be, even though it costs much less than any other listed system. Protel does not get the publicity, in the United States, that other systems enjoy, and part of this is due to a low marketing budget. Protel does not show up at the CAD shows. But I found, last year, calling many small companies, that in such companies, Protel was the most common CAD system. In larger companies it was Allegro. That a CAD system is in wide use is not an irrelevant statistic. If the system is widely used, there will be designers available who know it, and service bureaus which use it. I've never seen a PCB, in over 20 years as a designer, that Protel would not be able to handle. I'm sure they exist, but my point is that one of the higher-end systems might be overkill; and overkill means more overhead in setting up a project, so if the program is not right for the company's mix of work, more cost does not necessarily translate to faster work or even higher-quality work. Frankly, the task of choosing a CAD system, in many environments, is a very difficult one. Every system has its avid proponents, who will, quite honestly and sincerely, tell you that it is truly the greatest. And if one of them tries out another system, he or she will usually not like it. We are creatures of habit, and it takes time to build new habits and even more time until the new habits are as familiar as the old. In spite of my own prejudices, if all your designers knew OrCAD, for example, I'd probably suggest sticking with it. Most companies cannot afford to have their entire CAD department effectively shut down while everyone learns a new system, so, for a time, even if the switch is made, the company will be designing in two systems. I'd want a very good reason to change, and I would think long and hard about how to make the transition. If it is a totally new company, and the design staff has not been hired yet, then the matter would be a little easier. My inclination would be to recommend Allegro if money is plentiful and the expected design volume is large, and Protel if the company is small. If the design volume is small, I'd suggest qualifying a good service bureau instead, and pick a CAD system compatible with what the bureau prefers. [log in to unmask] Abdulrahman Lomax P.O.
