I'm not a fan of Capture. For a schematic front end to PSpice a lot of
people (especially long term pSpice users) still use Microsim Schematics
(that's what Jim Thompson did). I still use it and it works fine in
64bit windows.
OrCad SDT (the DOS schematic entry program) was probably the most
productive schematic entry program I've ever used. It's the Vi/Emacs of
the schematic world. Although I started using Protel/Altium in the 90's
I still used SDT as a front end until about 10 years ago.
It still has community support - for example VESA drivers supporting
resolutions of up to 1600x1200 (last time I checked) were written by the
user community.

Never had problems with that. In fact, cursor & mouse moved in
fixed steps, which was essential for the quick movements.
I even wrote a program that took the optimized sum-of-products
equations from PALASM2, created timing models from them and
made an Orcad subcircuit that allowed me to simulate the PALs
with the rest of my circuit in SILOS. It simply piped the drawing
commands from a file into the character input of Orcad. That looked
like a ghost drawing circuits at warp speed.
I also had a nice ECL100K library connected with the same mechanism
via Orcad to SILOS.

Orcad layout was buggy. We used Orcad schematics with PADS layout
and then transitioned to Visula on workstations.

Altium Designer now has NG-spice as simulator since version 19. Since
I have it, I should really give it a try. Stand-alone NG-spice looks
interesting.
cheers,

I thought Orcad was a drawing program that didn't understand circuits.
I remember a connection wire ending a couple of pixels away from a
pin, a visible connection that didn't actually connect.
PADS was a revelation. You couldn't hang a wire segment in space.
Connections weren't just line segments. You couldn't end a connection
anywhere but on a pin or a t-joint to another wire. It understood.
LT Spice will let you draw a visible connection that doesn't connect.
And you can scatter arbitrary wire segments anywhere in free space.

DOS Orcad was surprisingly good.
I remember discussing keyboard vs mouse entry with someone
that was using Mental Graphics stuff. He refused to believe
that schematics and PCBs could be easily created without
a mouse.
After 10 mins watching me use it, he revised his opinion.
I may still have a copy somewhere, but not the dongle.

It's pretty nice. I expected it to be a lot worse. It'll show various
things, like a frequency response curve.
I'd like to be able to extract the transfer function from a schematic.
Might be a bit much to ask. I've seen... various things, but ( for lack
of a better metaphor ), it'd be nice if it'd produce something that
could be massaged into a MATLAB tf() .... thing.
Dunno what use it is, but there's LiveSpice.
So you can enter the schematic of an audio widget and it simulates
it in real time against your audio hardware. Stuff like guitar pedals
for a start.
It all feels like early days for this stuff.

Dos Orcad capture was great. No circuit editor was more efficient
than that. We left Orcad when the Windows version came out.
A big step backwards. I remember how we pressed Xilinx to
provide Orcad libraries and a netlist converter to Xact.
And they gave in. Futurenet had no future.

LTspice is easy to run, you click the button. Lots of things relating to importing models and performing more complex analysis can be rather arcane.

Why is Tina a mistake? Is it not a good tool?
Any idea what is the difference between Tina and Capture/PSpice?

What I remember of Orcad Capture, admittedly in the DOS days, was how
terrible it was. Is it any good now?
I found LT Spice pretty easy to learn and use, at least for basic sims
of common circuits.

Yes, Tina was a big mistake.
But there's quite a learning curve with Capture/PSpice so I don't think
we'll see PSpice netlists posted in this group any time soon.
Anyway, Jim Thompson would have approved (maybe not so much with Capture...)
