Overview

Logimu: Circuit & logic gate simulator

The main goal of Logimu is to simulate large circuits at a high speed.

Features

  • Live simulation
  • Embed other circuits in the form of ICs
  • Embedded tests in a LISP dialect

Building

To build Logimu, you will need a nightly Rust compiler. Follow the instructions here. Then, run this:

rustup toolchain add nightly

Then go the the directory and build with

cargo +nightly build --release

You can then run the project with cargo +nightly run --release or by running the binary in target/ directly.

  • Direction of the components as a part of component configuration

    Direction of the components as a part of component configuration

    If the direction was a part of options as in Logisim, I'd say it'll improve UX. A handle near the component to rotate it will work nicely, too. Both can be mixed and help users grasp the logimu faster.

  • Simulator debugging + fix redundant program generation

    Simulator debugging + fix redundant program generation

    • When enabling simulator debugging, dirtied components are marked with a red dot.
    • The program was being regenerated even if the circuit did not change. An extra check to prevent this has been added.

  • Don't open /tmp/ok.logimu, implement

    Don't open /tmp/ok.logimu, implement "New"

    /tmp/ok.logimu was useful in very early versions but is no longer necessary or wanted.

    The "New" button was still unimplemented. It changes the current file path along with "Save as".

  • Fix incrementing input being clamped at max value

    Fix incrementing input being clamped at max value

    Clicking an input with the middle mouse button naively incremented the output. The output may overflow but got clamped by the I/O editor.

    This patchmakes the relevant code wrap the value around if it overflows.

  • Limit input and output range based on bit count

    Limit input and output range based on bit count

    Limits the range of possible input values to [0, (2^n)-1] where n is the bit width of the input. This only changes the behavior of the "Inputs & Outputs" gui dialog.

    Screenshots

    Previous behavior (allows any value, but applies a mask): before

    Modified behavior (limits the range, but the value is still masked): after

    Notes

    • If the value is guaranteed to never go out of range, applying a mask becomes redundant.
    • This range is meant to limit the possible bit sequences rather than values. E.g., say we have a 5 bit input. The allowed range then becomes 0..=31. This corresponds to all possible bit sequences of this input: 00000, ..., 11111. These bit sequences can, however, represent many different numerical ranges (or non at all), based on what encoding is used. ([0, 31] as unsigned integer, but [-16, 15] in two's complement) So in order to account for this in the future, it might be necessary to modify the range before setting it on the gui element.

  • Package requirements

    Package requirements

    Hello, I've tried to build fresh logimu in Docker and it failed several times until I installed some packages.

    I don't know Cargo well, but if it can detect the distro and recommend to install packages, that'd be great. Otherwise, those could be added in the README.md, so the whole build process is shortened with the length of packages to be installed.

    Anyway, there's my list for now:

    • pkg-config
    • libcairo-dev
    • libpango1.0-dev
    • libgtk-3-dev
    • libxcb-shape0
    • libxcb-xfixes0
    • libxcb-shape0-dev
    • libxcb-xfixes0-dev

    What is the preferable solution?
