# Eagle versus ORCAD versus ???

I have been an ORCAD user for decades. I read a lot of posts from EAGLE users complaining that a certain part isn't in the library. I can model a new IC (for drawing purposes) in ORCAD in a matter of seconds. Is it the SPICE models in Eagle that are not available? Is it hard to create new ICs in SPICE?
How does ORCAD compare with Eagle?
What other programs are popular? How do they measure up?

I used an older version of Orcad for some years and now found Kicad pretty much compatible, if not better.
There is a new version out this November.
Free and open source, no restriction on size of board etc.
Max.

I've been an Eagle user for over 15 years. Most of the parts that I use were created by me. Eagle is a schematic capture/ PCB board layout tool that is superior to Orcad. It has no simulation capabilities. I used Orcad back in the early '90s and it was great in its time, before it was bought out by MicroSim (?) and before Microsim was bought out by Cadence. Microsim integrated the Orcad schematic capture package with the PSpice simulation engine somewhere along the way.

I use PSpice for simulation projects that I have. I obtain the spice models from the manufacturers of the part that I want to use, which usually is not a problem.

So, I use Eagle for schematic capture and PCB layout, and Orcad/PSpice for simulation. This does mean that I have to redraw the schematic in one or the other program, whichever I do first. When I first started using Eagle, I found that its capabilities were superior to what was available at the time. I have used extremely complex capture/layout packages, like Mentor and the original Cadence (which I hate both) and still find myself going back to Eagle to do my layouts. I've done PCBs up to 6 layers in Eagle and I find the ease and simplicity of its use refreshing.

I never used Orcad but for me eagle is great program and has alot support behind for the newbie..

If you're pleased with ORCAD what's the problem? -- IOW "If it ain't broke why fix it?"

Thanks for the comparisons.

I'm having trouble getting PSPICE to work and wondering if it was worth it. I've recently reloaded my 16.6 up to 16.6 2015 but haven't had a chance to play with it yet.

I figured if Cern is heavily involved with Kicad it must have some value.

Max.

No problem

It's pretty hard for me to learn a cad or PCB without pictures in order to better help me understand and get it m. For eagle there are alot of people and companies that write books for free on using eagle and they break down for the newbie to understand .... I really like design spark and love playing with but the tutorials suck and turned me off cause it's a pain to keep them in order ,hear ,and or understand them.

I would reccomend Allegro, although it was not one of your options. I tried to work also with Orcad, but Allegro is much better.

Its because many "users" don't take the time to learn to make their own parts so they complain on the internet and hope someone will do it for them vs actually learning how to use that part of the program.

Happy Diptrace user here..
Prior to that I was modeling PCB's in Autocad because thats how they did it at my company.. yes.. PITA and I changed that real quick

I used Eagle for many years, and the last three I was working with Orcad 16.6 (not the dos version mind you) and I have to say orcad/allegro is far superior to eagle. The pspice is a "nice to have" feature, but the capabilities of the PCB package are far beyond those of eagle. Have you tried moving a trace or via in eagle without messing everything up? Or a bus of traces at a once?As far as I remember the only good way to move a trace that is next to other traces in eagle is to delete that area and route it again. Orcad will simply shift the adjacent tracks if you want to and let you move the trace, and will keep 45 degree corners instead of messing them up.
Online DRC is another great feature, it lets you put the traces right next to each other will keeping the required clearances, instead of checking, shifting things around and rechecking the DRC like you have to do in Eagle.

Try doing something like this in Eagle - crammed four layer board with 6 gigabit ethernets.
