Re: advice on selecting new PCB design package

Dax,

I'm impressed by your broad experience with these difference CAD programs,
even if I don't agree with all of your opinions!

OrCAD Capture is simply the best in it's class. It looks great and
works great.

As you say, "oh, come on!" :-) Here's a short list of things that are
annoying in OrCAD capture:

-- Tab-click works to select one of multiple overlapping objects, but this
doesn't work in conjunction with multiple select (ctrl+click)
-- The highest zoom level is artificially low
-- No means to set the "pick" radius
-- Pins for schematic symbols must be placed strictly around a rectangular
bounding box.
-- Pin styles are limited (there's a canned number of selections -- e.g.,
"short" and "long" for general purpose pin; no independent adjustment of pin
length)
-- Pin names can't be turned off on a pin-by-pin basis (it's all or
nothing! -- so you end up turning them all off and using text to display what
you want)
-- No ability to add or change keyboard mapping (!! -- this is, what, 2006?)
-- Macro language is half-baked; many functions you'd like to use (e.g., "zoom
area" with mouse input providing the bounding box) don't exist
-- No "area de-select" option
-- No polygon shape select
-- No way to toggle area select from "everything wholly within the selected
area" to "everything touching the selected area" from the keyboard
-- No tool-tips/status bar display/whatever of a net's name, class, etc. when
you select it (must double-click to bring up a modal dialog to obtain this
information)
-- Busses can only contain homogenous items, e.g., Data[0:7] -- you can't
create a "mixed" bus that also bundles in, e.g., CS, Rd, Wr!
-- No tabbed window view

I realize that many people aren's used to these features and therefore just
don't know what they're missing, but I find the biggest annoyance when using
multiple CAD programs is that you really start to miss nice features from one
in another. Better programs (e.g., those with full macros and keyboard
re-assignment) often let you emulate the other programs' functionality to a
large extent; such is not the case with OrCAD.

Compare that to the Cadence website where everything related to
support is under lock and key with a password unless you have a support
contract.

Did you mean Mentor? Mentor won't even let you access their web site
knowledge base for, e.g., PADS without a support contract. (I've mentioned
before that I really tend to think that PADS is somewhat like Oracle -- it's
really not that much better than the competition, but information about it is
purposely kept somewhat obscure so that there's an entire artificial industry
in training, support contracts, etc.)

I rated Electronics Workbench v9, the Frankenstein of EDA packages,
above Proteus and Eagle because EW is solidly in the professional
class.

Just curious -- what *does't* Proteus do that you'd like it to? I've never
used it, but on paper it looks pretty good. I certainly don't downgrade a
package because it also happens to cater to hobbyists (e.g., printing out
drill hole targets for manual PCB fabrication, as you mention).
