envision's Introduction

Envision

This software is not maintained. I built Envision and last worked on it during my engineering (2016) for acoustic communication research for underwater applications and have not worked on it since. I don't know if the code in this repository will even build anymore. 😂

Envision is a Dynamic Systems Simulator (similar to Simulink) written in C#.

Features

Block diagram based model design.
Built-in toolbox with facilities for:
- Signal generation (Digital, Analog, Noise)
- Visualization (Time Plotting + Spectrum)
- Basic Arithmetic operations
LiquidDSP integration, which enables:
- Complex signal operations such as FFT/iFFT
- FIR & IIR filters with filter designer for Butterworth, Chebyshev, Bessel etc.
- Over 10 (PSK, ASK, DPSK, QPSK, ARB etc.) Modulation/Demodulation methods with their 8, 16, upto 256 bit variations.
Signal sinks to write simulation results to file or to even play it using audio output H/W (e.g., speaker) on the host.
IronPython integration to enable writing custom simulation components.
- Envision can load python files at startup and expose python functions as blocks.
- Also has a Python block with syntax highlighting editor which enables writing python scripts directly within the model editor.
Block interface which can be implemented and added as extension to Envision through external DLL files built using any .NET Runtime compatible languages (C#, VB .NET etc.)
