I absolutely have contempt for a schematic entry program that allows things that are visually connected to be not really connected. And for tools that crash, and crash more if you enable auto-backup. PADS does neither.

I do what I enjoy, not what anybody tells me to do. I like to draw, so I do it. Sue me.

Two lighthouses, actually.

How do you feel about upside-down grounds?

I know you didn't ask *me*, but...

I'd rather have the usual kind, but I don't have a problem with this one. In fact, I'd prefer it to one that has one or two 90 degree bends in the connecting wire.

I used connections similar to this on my schematics to emphasize that the wires need to be connected at one and only one point, usually to a ground lug. The technician building the gear knew exactly what I wanted and he knew I would inspect for it.

I don't like connection-by-netname, either, but I've been known to do it (local power is one reason).

Some of us don't get to choose our tools.

They look too much like antennas. I don't much like upside-down power bars either, but bending a wire around to a negative power supply isn't any prettier.

If that suggest reality, I have no issue with it. Some don't like angled signals, at all, but often it makes a lot of sense (cross-coupling and bridge structures, come to mind). If I can suggest a physical property in the schematic by drawing something unusual, I'll do it.

Oh yeah, three different media. With Orcad me no take no chances no more :-)

What, you had that turning gray of probe pins happen, too?

I got a chuckle out of the "smoke parameters". But it doesn't have a BANG device.

No, Remember I don't use Crapture, but can convert my schematics to Crapture upon request... without ever opening Crapture ;-)

Eagle doesn't either as long as stay-on-grid is turned on. If it ain't you can move a part and if the wires tag along it's connected.

Orcad also seems fussy about replacing parts. Delete one, pick new part, move over, click to place ... refuses. Same symbol, no dice. First the wires need to be deleted, part placed, then new wires drawn. Probably I didn't use some magic trick but man, that's the opposite of intuitive.

Copying a part over an old part should work. You can't copy it somewhere else and drag it into position, though. OrCAD won't let you move anything that would change a connection (i.e. a move can't cause a change in the netlist); copy can.

Check that you have Options->Preferences->Miscellaneous->Wire Drag->Allow Component Move With Connectivity Changes checked? (It isn't checked after a default installation.)

Also, in case you aren't aware of this... if you Alt-drag a part, it'll purposely *not* drag its wires along with it. (...and Ctrl+dragging a part duplicates it, as happens in most Windows programs.)

---Joel

Just tried it but unchecked it again. It does then accept parts to be scooted into position but when moving them it breaks connections. Not so cool. Cadence should buy a copy of Eagle and see how it's done :-)

Another annoying "feature" of Orcad is that it pushes wires upon block moves. Meaing some cleanup after evey move, including some contortion art. Makes no sense. SDT didn't do that, but that was from the good old times.

It wasn't in earlier releases but I think it is now. I've never changed that option and no one would have done it for me.

...which is stupid because Ctrl+drag is also how you select components in an area. OrCAD likes to confuse the two and you get an area selected and copied on top of itself (and both still selected). Good thing Ctrl-Z is handy.

You can Cntl-uncheck wires before the move. Uncheck them in the segment

The word "crapture" has become trite, especially when used three times in one sentence.

Please, Jim, tell me you're not developing a feces fetish like your most recent admirer.

The older ones are definitely more stable. They got heavy on theft deterrence, and those checks, and that detection engine is part of why the newer versions suck so badly. They suck so bad, they suck at sucking.

Anyway, 13 thru 15 are nice. 15 works good on a laptop (hey, if I own the license, I should be able to run it anywhere).

We used to buy software dongle replacements from a house in Canada.

That is the most retarded prognosis I have ever seen.

I'll bet his box will run blu-ray video stream level stuff, no problem. That is GPU AND CPU intensive decode and render routines, AND reads AND writes to swap AND ALL the RAM. I'll bet his hardware is fine.

Your prognosis is pathetic.

RAM OR a hard drive? Which is it, boy? What a joke.

IF his hard drive was giving errors, they would still be there. He would have said something.

I'll bet those machines you have were NEVER cleaned by their owner, and they ran hot most of their life, and even up until failure. (He'll come back and claim that they were 'clean as a whistle'). Good chance that you failed them too. With a garage full of junk, it would appear that what you have is anything but "The Midas Touch".

Have you tried zero?
