SciLab - A Small Sized Open-Source Alternative to MATLAB

Picture1

Scilab is an open source, cross-platform numerical computational package and a high-level, numerically oriented programming language. It can be used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations, numerical optimization, and modeling and simulation of explicit and implicit dynamical systems. MATLAB code, which is similar in syntax, can be converted to Scilab. Scilab is one of several open source alternatives to MATLAB.

Scilab is a high-level, numerically oriented programming language. The language provides an interpreted programming environment, with matrices as the main data type. By utilizing matrix-based computation, dynamic typing, and automatic memory management, many numerical problems may be expressed in a reduced number of code lines, as compared to similar solutions using traditional languages, such as Fortran, C, or C++. This allows users to rapidly construct models for a range of mathematical problems. While the language provides simple matrix operations such as multiplication, the Scilab package also provides a library of high-level operations such as correlation and complex multidimensional arithmetic. The software can be used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations, and numerical optimization.

Scilab also includes a free package called Xcos (based on Scicos) for modeling and simulation of explicit and implicit dynamical systems, including both continuous and discrete sub-systems. Xcos can be compared to Simulink from the MathWorks.

As the syntax of Scilab is similar to MATLAB, Scilab includes a source code translator for assisting the conversion of code from MATLAB to Scilab. Scilab is available free of cost under an open source license. Due to the open source nature of the software, some user contributions have been integrated into the main program.

PID Simulator

pid

As obvious from the name, this software help in simulation of various PID controllers by merely changing their parameters. It may not be more useful at industrial level, but (I hope) students will find it helpful for their studies.

On a friend’s request, I searched for PID tuning software but could not succeed. Instead, I found these 5 (1 excel file and 4 exe). A brief description and download link of each of them, is given below:

  1. PID Loop Simulator: This tool simulates a control loop consisting of a first order process with deadtime and a PID controller.
    • How to use: The process is specified by the process gain, time constant and dead time. The PID controller has 3 parameters: gain, integral and derivative. Key in these values into the appropriate cells. If the integral time is keyed in as 0, the integral term is ignored.
    • Personal comment: Nice!!
  2. PID Simulator 1.0.0.6: PID simulator is a simple PID simulator designed to help you get a feel of how to tune a PID by adjusting the various properties.
  3. PID Simulator: The module gives time and frequency domain views of the responses of a closed-loop system consisting of a PID controller and a process model. Many process models can be selected, controller parameters can be changed interactively, and the resulting responses are displayed instantaneously.
    • Personal comment: Probably the 2nd best.
  4. PID Loop Shaping Module: This module will give you insight into loop shaping using PID control.
  5. CONTROLLER TUNING 101: This is the best PID simulator I could find, but unfortunately, this is a demo version. I did not observe any restriction in the demo version so far. It provides controller input fields with the help of a block diagram, which is quite helpful. After setting the values, click the ‘Run’ button to view the output graph.
    • Personal comment: Best but Demo version.

RECOMMENDATION: Since, the total download size of the 5 simulators is less than 4MB, I shall recommend you to download and try each of the simulators. This will help us finding which of these is best.

Proteus 7.7 SP2

proteus7.4L(1)

The Proteus Design Suite is wholly unique in offering the ability to co-simulate both high and low-level micro-controller code in the context of a mixed-mode SPICE circuit simulation. With this Virtual System Modeling facility, you can transform your product design cycle, reaping huge rewards in terms of reduced time to market and lower costs of development.

If one person designs both the hardware and the software then that person benefits as the hardware design may be changed just as easily as the software design. In larger organizations where the two roles are separated, the software designers can begin work as soon as the schematic is completed; there is no need for them to wait until a physical prototype exists. In short, Proteus VSM improves efficiency, quality and flexibility throughout the design process..

What is Proteus VSM?

Proteus Virtual System Modeling (VSM) combines mixed mode SPICE circuit simulation, animated components and microprocessor models to facilitate co-simulation of complete microcontroller based designs. For the first time ever, it is possible to develop and test such designs before a physical prototype is constructed.

This is possible because you can interact with the design using on screen indicators such as LED and LCD displays and actuators such as switches and buttons. The simulation takes place in real time (or near enough to it): a 1GMHz Pentium III can simulate a basic 8051 system clocking at over 12MHz. Proteus VSM also provides extensive debugging facilities including breakpoints, single stepping and variable display for both assembly code and high level language source.

Circuit Simulation

At the heart of Proteus VSM is ProSPICE. This is an established product that combines uses a SPICE3f5 analogue simulator kernel with a fast event-driven digital simulator to provide seamless mixed-mode simulation. The use of a SPICE kernel lets you utilize any of the numerous manufacturer-supplied SPICE models now available and around 6000 of these are included with the package.

Proteus VSM includes a number of virtual instruments including an Oscilloscope, Logic Analyzer, Function Generator, Pattern Generator, Counter Timer and Virtual Terminal as well as simple voltmeters and ammeters. In addition, we provide dedicated Master/Slave/Monitor mode protocol analysers for SPI and I2C - simply wire them onto the serial lines and monitor or interact with the data live during simulation. A truly invaluable (and inexpensive!) way to get your communication software right prior to hardware prototyping.

Should you wish to take detailed measurements on graphs, or perform other analysis types such as frequency, distortion, noise or sweep analyses of analogue circuits, you can purchase the Advanced Simulation Option. This option also includes Conformance Analysis - a unique and powerful tool for Software Quality Assurance.
Co-Simulation of Microcontroller Software

The most exciting and important feature of Proteus VSM is its ability to simulate the interaction between software running on a microcontroller and any analog or digital electronics connected to it.

The micro-controller model sits on the schematic along with the other elements of your product design. It simulates the execution of your object code (machine code), just like a real chip. If the program code writes to a port, the logic levels in circuit change accordingly, and if the circuit changes the state of the processor's pins, this will be seen by your program code, just as in real life.

The VSM CPU models fully simulate I/O ports, interrupts, timers, USARTs and all other peripherals present on each supported processor. It is anything but a simple software simulator since the interaction of all these peripherals with the external circuit is fully modeled down to waveform level and the entire system is therefore simulated.

VSM can even simulate designs containing multiple CPUs, since it is a simple enough matter to place two or more processors on a schematic and wire them together.

INSTALL INTRUCTIONS:

  • Uninstall old versions of Proteus first.
