antares's Issues

Default light color property isn't applied

There are currently 2 issues with the circuit's "Default light color" property:

• It doesn't get applied when adding light emitter components such as LED
• The property editor tells "From system settings", but the color displayed in the dropdown is always white

Highlight addressed cell in desktop memory view

When the simulation is running, highlight the cell that is currently being addressed if the memory component is openend in a desktop view.

UnexpectedError when dragging wire

When dragging wire from right to left and going over the starting point, an unexpected error occurs (see attached movie).

Choose bit width in Delay component

Allow the user to set the bit width attribute of delay components.

Cannot open circuit after moving to another folder

After moving a circuit from its current folder to another folder, the circuit can't be opened any more afterwards.

Draw inactive Controls as "disabled"

Controls are interactive elements from sub circuits that are placed on the symbol of the sub circuit. If flat simulation is used AND the sub circuit uses a script, the models of the controls are never really updated during the simulation. Such Controls in symbols can confuse the user, for example when the display (the initial value) 0000 as the content of a register, although
this doesn't reflect the real value. Therefore, draw those controls as "disabled".

I18N support in text component

Allow the user to translate the text of a text component

Preference setting for switch propagation delay

Add a new preference setting for configuring the default propagation delay of switches. This value will also be used as propagation delay when the user clicks on a circuit input. Version 0.3.0 uses a hardcoded value of 1'000 ns for interactive circuit input clicks, which is too large compared to typical gate propagation delay, because it will dominate in graphical signal curves in the upcoming oscilloscope feature.

Undoing complex wiring can fail

Undoing complex wiring using the undo system (especially when using junctions and) can sometimes scramble the wires. This is due to the fact that the design of the undo system uses "undo logic", which is error prone. Explore using a "event sourcing" based approach.

Transistor

Add a transistor component (n-type, p-type)

Splash screen not shown at start-up

Although a splash-screen is part of the software (and displayed when starting the built JAR directly), it is not displayed when starting installations that have been installed by the installers. At least on macOS.

Statistics for "deep" and "flat"

Version 0.1 of Antares calculates statistics (number of components per type) only by deep traversal in the circuit graph, recursively expanding all subcircuits. It would be interesting to see to what degree the component graph is cut down by using scripts. Calculate two separate statistics, one for "deep" circuit structure and another for "flat" circuit structure.

Renaming circuit when clicking breadcrumb

Small suggestion concerning the renaming of a circuit: It would be convenient to have the ability to double-click the breadcrumb in order to rename the current circuit, which could be confirmed by pressing the enter key.

Sharper icons

The icons look quite blurry, especially on high resolution displays. Add higher resolution icons and choose depending on the screens DPI.

Incorrect layout after closing main view with sub views

1. Open a circuit in a main view
2. Open a subcircuit in a sub view
3. Close the main view
4. Re-open the main view
   => The circuit in the main view is positioned as there was an open sub view (to much to the left)

Alignment attribute in text component

Allow the user to set horizontal and vertical alignment property of text components.

Break component

Introduce a new break circuit component with one input. If the input is asserted, the simulation is suspended if it runs in single step mode. This can be used for example in a microprocessor circuit to implement a "single machine instruction" mode if a breakpoint is activated whenever the microprogram returns to address 0.

Repainting errors in text components

If the text of a text component (or a rectangular component containing text) is larger than the surrounding box, repainting errors occur when moving the component.
Fixes:

• Respect text bounding box when calculating text component bounding box
• Clip text to surrounding box in case of rectangular components (rect, ellipse etc.)

Show scripts even if not circuit author

The properties of an object can only be edited by the author of a circuit. Since script properties show their scripts in a popup editor, an Antares user is not able to inspect the scripts of standard library components, because he is not the author of the standard library circuits. This prevents Antares users from studying the scripts used in the standard library.

Change the property editor of script properties such that it opens the script in a read-only popup editor.

Simulation is not stopped when circuit is closed

If the main circuit is closed by the user during simulation, the simulation isn't stopped.

Extend scripting DSL

Add the following functions to the scripting DSL:

• Word.subword()
• Word.shiftLeft()
• Word.shiftRight
• CircuitElemModelBridge.load()
• CIrcuitElemModelBridge.store()
• CIrcuitElemModelBridge.hexWord()
• CIrcuitElemModelBridge.undefinedWord()

Pull resistor

Add a new built-in component that allows to add pull-up and pull-down resistors to circuits.

More port descriptions in standard library components

Gate symbol types in library trees

Change the icons for logic gates in the library tree according to the currently selected symbol type (ANSI/IEEE, ICE)

Codec:4-16 Decoder can't be opened

The "4-16 Decoder" of the standard library can't be opened. Exception "Illegal argument: isPort with name 'I0' already contained".

Draw text of selected rectangles

When selecting a rectangle with a text, the text is currently not drawn. The selection model consists only of the boundary of the rectangle. This can lead to disorientation when selecting multiple rectangles with text. Display the entire contents of the rectangle view using the selection color.

In addition, in order to make this work correctly, it is necessary that component draw their background with full transparency when being selected.

Choose user language in preferences

The language in which the UI is presented is currently taken from the operating system settings. In addition, a command line parameter allows to choose the language at startup time, although this is not transparent to the normal user. Let the user change the language in the preferences window. Antares has to be restarted after changing that preference.

Inconsistent editability of memory contents

• memory contents should be editable even when opened during simulation
• don't allow to edit RAM while in edit mode (as it is reset when simulation is started)
• update main circuit after cell has been changed
• same edibility of memory contents in popup and in desktop subview

Suggestion: add one or multiple small videos to the front page

As the title says: create some short videos without sound for the Antares front page (and maybe also for subsequent pages.

For example like this (it's a little big though and unfortunately a GIF):

I think Antares capabilities are much more apparent in videos.

Alternatively put some screenshots on the front page 😉

Too short circuit input propagation delay when clicked

Circuit inputs can also be toggled by the user with the mouse, if they are part of the top-level circuit. Their default propagation delay of 1 ns is also applied when being clicked by the user. If a circuit input (with attribute "toggle" unset) drives the clock input of a D-flipflop, a very short click/release by the user doesn't trigger the flipflop, because the resulting impulse is too short for the edge detection component of the D-flipflop is implemented in the standard library, especially if the current simulation speed is small.

When being clicked by the user, a circuit input should apply the same propagation delay like a normal switch, something like 1000 ns.

Don't highlight memory cell if CS not asserted

If a ROM or a RAM is not selected (i.e. the CS input is not asserted), the memory contents view should not highlight the currently addressed cell.

Dark UI theme

The FlafLaf look & feel used by Antares already supports a dark theme. When using a dark Antares theme (such as "CRT"), the UI should also use the dark FlatLaf theme

Improve unexpected error window

Hi @flandreas

Small suggestion for the unexpected error window:

It would be helpful if you added something like a "copy error to clipboard" button and added a clickable link to the right bug tracker (I assumed it's this one.)

Hint for other users wanting to report an error: Go to "File/Export Log file". Open the generated zip file and copy the relevant exception (Most likely starting on a line containing "ERROR".

Library folder "Frequently used"

Both built-in libraries "Base" and "Standard" should have a folder containing frequently used components: Input, Output, Switch, LED, NOT, AND, OR.

Rotate ports and pins

In addition to set the orientation of ports (inputs, outputs and input/outputs in the circuit editor) and pins (in the symbol editor), ports and pins can now also be rotated by 90 degrees counterclockwise using the keyboard or the menu item.

Properties not visible with initial settings

When starting Antares the first time with initial settings, the properties panel in the lower left part of the window is not visible, because the library tree takes too much space. This confuses users.

Menu items for switching views

Add menu items (including accelerators) for switching between circuit editor and symbol editor.

Error when starting simulation

Hi @flandreas

Very nice progress in Antares 0.3.0, congrats!

So I played around with Antares 0.3.0 and following exception occured, when I clicked on the yellow highlighted part of the imported Tannenbaum project (looks very neat btw!):

Reconnect wire to existing wire

The end of a connected wire can be dragged around and be reconnected to another port or left open, but it is currently not possible to reconnect it to an existing wire to producing a junction.

Help menu for online manual

Add a help menu with a menu item "Documentation" that opens the online manual from antarescircuit.io in a browser window.

Texts don't have border or fill by default

Texts added using the text tool now don't have borders and are not filled by default

Wire description and tooltip

Allow the user to set a description attribute on wires, and show it a a tooltip. During simulation, show also the current signal of the wire in the tooltip.

Customizable tunnel symbol

The choice of the Antares tunnel symbol might be questionable. Implement an alternative, more standard-like "arrow" symbol and let the user choose in the preferences which one he wants to use.

Open circuit in navigator with ENTER key

Pressing the ENTER key in the navigator allows to open the circuit currently selected in the tree.

Doesn't start in initial environments

Antares 0.3 cannot be started on environments (PCs) where it has never been executed. When starting, it looks for the file "Antares.pref" in the application's home directory and refuses to continue if the file is not found.

Copy/Paste in symbol editor broken

Copy/Paste in the symbol editor has been broken with version 0.2. Fix and add unit test.

Slow clock causes high CPU load

When using a clock at 1 Hz even in a minimal circuit, the CPU load is too high during simulation. This is because the simulation engine is busy polling the simulation queue at a high frequency. Improve the polling strategy by deferring the next polling to the smallest execution time in the simulation queue.

Snapping of graphical component doesn't work

Pure graphical components like rectangles or circle don't perform component-to-component snapping, but just snap at the component's location. Instead, a rectangle should snap at its both sides and at the center, both horizontally and vertically. The reason for the bug is that graphical elements are wrapped by special wrapper when being added to a graph drawing, and this wrapper doesn't correctly forward snapping behavior to the wrapped graphical component.

Gap between wire and OR gate with American symbol style

The endpoint of wire that is connected with an OR gate pin is at a location that is suitable for European block-like symbols, but not for American style symbols.

Descriptions in rectangular components

Rectanguar components like rectangles and circles now have a description property. The description is displayed as a tooltip if the mouse is moved over the displayed text of the rectangle (if there is a text at all). This is primarily useful for rectangles of style "Subsystem", where it can be used to explain a subsystem in more detail.
