Logisim doesn't really emulate the hardware well enough to give you a a reasonable way, so effectively no.

ok, then ill connect the J and the K and put an inverter between them...

That's actually just as useful!!
I need help with Random (x86 Happy), pm me if you want to help :D
LOOK IN MY SPOILER, MY SIG IS UPDATED (almost) EVERY DAY
Spoiler For MiniTale:
No mini competition please, teamwork is better :D
I suggest we do not use "MiniCraft" as the name:
Notch has asked us to not do that.
It will get changed to "MiniTale"
@Hayleia, you don't _have to_ organize :P
THIS POST IS IN MY SIG TOO

Details
Language: Axe
Platform: TI 83+

Things we'll need to do/make
Draw the sprites saintrunner is working on this
A save file format.
A level generator.
A Tilemapper.
Some sort of AI.
Crafting system.

And even more:


[07:53:14] <+Frey> Y'know, when people descend from my heavens , they're never Chuck Norris
[07:53:55] <+Frey> I usually get another catgirl or an angel pops down for a visit
[07:54:06] <+Frey> Some angels are really nice
[07:54:33] <+Frey> Some are into the whole "scare the locals" bit
[07:54:54] <+Frey> And some just absent minded
[07:55:38] * +david_ has nothing to do
[07:55:40] <+Frey> It's the absentminded ones you gotta look out for, because the'yre the ones that forget they're 40ft tall
[07:56:04] <+Frey> They're also the ones that forget about social taboos, like nudity
[07:56:28] <+Frey> Have you ever tryed to explain to an angel...anything?
[07:56:45] <+Frey> They don't listenunless they want to
[07:57:16] <+Frey> And don't learn unless they think they don't know
[07:57:51] <+Frey> Except for the nice ones, they're nice
[07:59:27] <+OmnomIRC> (O)<yrinfish> lol
[07:59:32] <+Frey> And they're all so pretty!
[07:59:38] <+Frey> It's ridiculous
[07:59:44] <+OmnomIRC> (O)<yrinfish> I hate PUSHES, THEY HAUNT ME
[08:00:06] <+Frey> Want an angel to come over and exorcise them?
[08:00:36] <+OmnomIRC> (O)<yrinfish> or, more specific: the fact that sometimes, happy outputs: pushes != pops
[08:00:47] <+OmnomIRC> (O)<yrinfish> I know why
[08:01:01] <+OmnomIRC> (O)<yrinfish> and I can solve it by adding a lookahead
[08:01:10] <+OmnomIRC> (O)<yrinfish> But I don't want to
[08:01:24] <+OmnomIRC> (O)<yrinfish> but continue your story
[08:01:35] <+OmnomIRC> (O)<yrinfish> lol
[08:03:13] <+Frey> Ok, so one day, I was walking to the school bus, and, long story short, got my life saved by an angel
[08:03:27] <+Frey> This one was a scary one
[08:03:42] <+Frey> Same height/age as me
[08:04:14] <+Frey> OMG She was the scariest person I had ever met
[08:04:28] <+Frey> She made the entire football team pee their pants
[08:04:43] <+Frey> I was so glad she was on my side
[08:05:04] <+Frey> Right up until she tryed to enter the bathroom with me
[08:05:37] <+OmnomIRC> (O)<yrinfish> lool
[08:05:45] <+Frey> After a muchness of arguing, I finally got through to her
[08:05:56] <+Patrick-D> is this a rap song?
[08:06:06] <+OmnomIRC> (O)<aeTIos> idk
[08:06:09] <+Frey> She tap danced outside my stall the entire time, though
[08:10:04] <+Frey> She was in all my classes too, which was weird, especially as they were all advanced courses and she joined in the middle of the semester
[08:10:28] <+Frey> Even the teachers were scared of her
[08:10:45] <+Frey> Note that she was gorgeous
[08:12:09] <+Frey> So, this angel and I, we managed to stop the apocalypse
[08:12:48] <+Frey> And she kissed me before going back,
[08:13:08] <+Frey> To heaven, but as it turns out that kiss sealed her to Earth
[08:13:47] <+Frey> We still don't know what to do

Seriously, people. Verilog.

What, exactly, is to be gained by having a gate-level schematic of a microprocessor? If that image is part of your tutorial, then you are far from keeping this tutorial simple. You are treading in a territory that electrical engineers have long forsaken and (I assume) have no intent of returning to.

Well, one thing to be gained by me is a grade :P

I also just posted this because multiple people have made posts describing gate level schematics.

Also, the image isn't part of the tutorial. That's much worse than what the actual tutorial CPU will be.

If your school project is to make an Electrical Engineering major have a cerebral infarction or an aneurysm-hemorrhage, then you get full credit plus some! X_x

I'm glad that image isn't part of the tutorial but still. Some things were never meant to be described on the gate level for reasons of sanity, time, space, and understanding.

For the record, I'd just like to state that I'm not trying to flame or troll or insult anybody. Rather, as an EE Major, I am compelled to ... emphasize certain things. If y'all want to build simple microprocessors at the gate level, be my guest. I warned you twice or thrice about how masochistically insane it can be. As Qwerty's brain-buster image so demonstrates, this stuff gets complex fast. The amount of time you'll spend debugging something like that will grow exponentially to the point you may as well call it outright impossible.

I've spent less than five minutes debugging that microcode instruction ROM and it works perfectly...

I *did* spend an hour wiring it up, though.

You're either really good or really lucky or both. Fact of the matter is, it's still a pain in the butt. I've spent more time debugging simpler circuits. Furthermore, what's the practical application of creating a simulated schematic like that, anyway?

There's pretty much no practical application for it, except a general understanding of how computers work at their most basic level.

I guess that's a worthy reason but it's not exactly a marketable one unless you're going into microprocessor design for a career. Personally, if you want to just generally understand how computers work at their second-most basic level (most basic would be literally arrays of transistors), I'd suggest playing around with simpler sequential logic machines. Build a simple vending machine facsimile or a simple cruise control analogue. They're much, much less difficult in comparison and they teach the general concept of computers as state machines and how volatile memory works.

I know, designing a vending machine was the *other* project we had to do...

I didn't use state machines to design any of the circuits in that diagram, though ;)
Way too much work to draw out the transition table for such a complex device.
