elec-sim

This is a simple FOSS logic simulator program. That's it.

Running the source

Using Eclipse

Linux

Download the zip and extract it into your eclipse workspace. Open eclipse and navigate to src/main/java/com/cospox/elecsim/main.java and click run.

Other platforms

Follow the linux instructions but before running there is one extra step. Navigate to lib32 or lib64 (depending on your architecture) and select the files ending in yout OS. Right-click them and choose build path->add to build path. Then click run and it should work.

Using Java without Eclipse

Tutorial to come when I figure it out myself.

Licence

wtf is a license anyway, pfft. Just use the code, I don't really care. Just don't sell it for money. Keep any changes free and open source.

See licence.txt.

Processing

This program uses the Processing library (https://processing.org/) and I have included a copy of their licence at licence-processing.txt.

Critical bugs

As this is a new (and alpha) project, there are a few recognised critical bugs in the codebase. Most of the bugs arise from the behaviour of ctrl-z. To completely remove the chance that these bugs happen then after ctrl-z'ing, save the file and reopen the program therefore it is impossible for the bugs to occur. I'm working to resolve the bugs however it is insanely complex.

elec-sim's Issues

Some UI elements do not respond to font changes, i.e. top-right

Save prompt on open new file needed

Some component movements cannot be undone

Cannot select wires in '90 degree' mode, only 'straight mode'

Components snap to an invisible/visible grid

Undo does not undo moving components

Does not open most recent file on startup

Close button/action

After saving from the exit menu the window does not close

In 'square' wire mode, the click detection is a bit off

Setting to set how many logic iterations per frame

TEST ISSUE

When exiting, the save option does nothing

Undo history is not cleared after opening file

The text at the top right is slightly too far down

When the andgate is selected the red outline has a bar through the middle

Cannot terminate wire termination after started

Visual wire bug

When selecting a component to attach a wire to for the first time after opening the program the visual trace from the component to the mouse does not show.

Connections very hard to click on

Ctrl-z after deleting wire does not work

Add redo action?

Wires don't get selected by ctrl-A
