Re: Concurrency

The main problem that I see is what happens when many inputs are effected by any one particular signal change (concurrency) - - in particular, from a clock. In the sample that I put together, this is a series of shift registers. No problem occurs if each register is handled after the one which it ...

Re: Concurrency

It is not a problem that I have but one that I have anticipated. I don't know how your program handles concurrency over multiple devices, but when many devices must operate concurrently it is important that none be handled by the software before any of the others, because the operation of those may ...

Concurrency

I have run into something with your program that you should look into. The main strength of digital logic circuitry (hardware) is its operational concurrency. Software, on the other hand, is almost totally sequential in operation. This is one of the main strengths of hardware operation, but it is ...

Binary to BCD Converter

I am enclosing the files for a 32-bit Binary-to-BCD converter. It uses the standard approach. I plan to give further info on it later, however, it takes a binary input in the bottom 29-bit register, LSB to the right. Basically, to convert:
1. Zero the Binary register using the button to the left.
2 ...

Active Files

Is there a way to attach and upload a working file, so that the others can run it? If so, I'd like some instructions.

Zoom?

Is there any way to "zoom" a diagram? I have created one that is over twice the screen width, but I need to be able to observe the whole diagram when it is being executed. An exported copy of the diagram is easy to read on the screen in a zoomed state.

Re: Input

Yes, I finally came around to that. It feels a little awkward at first, but you do get used to it. This is a very robust program. It doesn't seem to jump around and give crazy results like those programs from a certain multi-multi billion dollar company. This is very good, and it allows some rather ...

Input

I am new to this software package, but not to logic design. My particular question is"how do you tie inputs to power or to ground?" In particular, how can you implement a switch or push-button to supply a power or ground to an input? Finally, what does your "button" provide to the input?
