Package: klogic
Version: 1.63-1
Severity: wishlist
Hi,
I've looked for a simple digital logic simulator to play around with
some circuits and it seems that all the applications in Debian for
this are seriously lacking in either features or simplicity. But
klogic seems to be by far the best for just connecting a few logic
gates and seeing the result. If only it wouldn't crash so often but
that is another bug. But some things are still missing which I think
should be there:
1. Sub-Circuits should have a configurable width and the labels for
connectors should allow more chars.
2. The size of the workspace should not be limited. I suggest creating
a bounding box around all placed objects and using that box to
calibrate the sliders in the scroll bars. But the arrow keys in the
scroll bars should allow scrolling outside of the bounding box and the
bounding box should grow when an item is placed outside it.
3. Simulation should have more running options. It is nice that one can
single step the simulation or let it run. But as designs become more
complex it will take more and more cycles for hange to propagate. It
would be nice if one could run the design untill the output stabilizes
and/or until a clock source changes. If a button is pressed or switch
toggeled the simulation could run again till it settles into a stable
state (assuming no clock source there).
4. The logic needs more values. Currently only high and low values are
known. But for example a tri-state has a thrid value "neutral" where
it does not influence the wire. In the graph this could be shown as a
line half way between high and low. There can also be a fourth value
"short circuit" when two outputs with different values are
connected. In the graph this could be shown as a crossed out (or
stippeled) box ranging from high to low.
5. Some more primitives would be nice.
- multiplexer: e.g. one data in, 4 address bit in, 16 data out,
address says with output gets the data input, rest is neutral (via
tri-state)
- demultiplexer: reverse of the above. address selects which of 16
inputs becomes output
- led matrix / visible ram
The current ram primitive could display the contents of its ram
as a matrix of leds.
- identity gate
Sometimes you want to delay a signal by one cycle, for example to
avoid the output flickering when the path length differ. It would be
nice if there where an identity gate that would just add a delay.
