Proteus Design Suite

Author : Lab center

Website : http://www.labcenter.com/download/

Licence Type : Freeware

Size : 267MB`

Limitations of the Demonstration Version

The Proteus Professional demonstration is intended for prospective customers who wish to evaluate our professional level products. It does not allow you to save, print or design your own microcontroller based designs (you can however write your own software programs to run on the existing sample design suite for evaluation), but does include all features offered by the professional system including netlist based PCB design with auto-placement, auto-routing and graph based simulation.

Licence Type : Freeware

Size : 407 MB

Description : MPLAB® X IDE is a software program that runs on a PC (Windows®, Mac OS®, Linux®) to develop applications for Microchip microcontrollers and digital signal controllers. It is called an Integrated Development Environment (IDE), because it provides a single integrated “environment” to develop code for embedded microcontrollers. MPLAB® X Integrated Development Environment brings many changes to the PIC® microcontroller development tool chain. Unlike previous versions of the MPLAB® IDE which were developed completely in-house, MPLAB® X IDE is based on the open source NetBeans IDE from Oracle. Taking this path has allowed us to add many frequently requested features very quickly and easily, while also providing us with a much more extensible architecture to bring you even more new features in the future.

SVC Filter Design Program

Author : Tonne software

Licence Type : Freeware

Size : 1.5 MB

 SVC filter is a program designed to expedite the design and analysis of lowpass (and highpass) filters with nearest 5% component values. SVCfilter is 32-bit Windows® electrical filter design software nicely written to help the radio amateur, technician or engineer design and analyze lumped-element lowpass and highpass filters.

SVC filter features

  • Cutoff frequency is entered in the usual text box and can be from audio through UHF.
  • Cutoff frequency can be as low as 0.1 Hz, allowing the value of .159155 [ i.e., 1/(2*PI) ] to be used.
  • The graphic output draws the schematic of the filter you have designed, and also plots the responses of that filter (both transmission and reflection). It selects the nearest 5% values for the capacitors and shows those values as well as the exact values and overlays the response plots for the nearest values on top of the original exact-value plot.
  • Tuning buttons allow stepping the cutoff frequency up or down in 1% steps and immediately seeing the new performance of the redesigned filter on the plot.
  • Place the cursor anywhere on the plot and see the transmission, reflection, VSWR and envelope delay values for that frequency.
  • Click on the “Write Elsie File” button to write a file to drive Elsie the filter design and analysis program for followup filter examination in even greater detail.
  • Click on the “Write Spice schematic” button to write a file to drive the LTspice simulator.

NGSPICE Circuit Simulation

Author : NGSPICE

Licence Type : Freeware

Size : 5.2 MB

NgSpice – one of the popular and widely used free, open source circuit simulator from Sourceforge. NgSpice is developed by a collective effort from its users and its code is based on 3 open source software packages:- known as:- Spice3f5 , Cider and Xspice. Ngspice is a part of gEDA project which is growing every day with suggestions from its users, development from its contributors, fixing bugs and approaching perfection. As its a collaborative project you can suggest improvement of the circuit simulator and be a part of the development team.



Gnu Circuit Analysis

Author : GNUCAP

Licence Type : Freeware

Size : 1.19 MB

GnuCap – is another open source project, developed as a general purpose circuit simulator. Known widely as GNU Circuit analysis package, this linux based circuit simulator performs various circuit analysis functions as dc and transient analysis, ac analysis etc. Developers have incorporated spice compatible model for MOSFET, BJT and Diode.



CircuitLogix Circuit Simulation

Author : CircuitLogix

Licence Type : Freeware

Size : 9 MB

CircuitLogix – this student version software from CircuitLogix enables you to perform analog, digital and mixed mode circuit analysis and simulation.  This SPICE simulation software provides 4000 devices on its student version which is 1/3 of the pro version. This circuit building software give access to switches, linear IC and digital IC, FET, Transistors, relays, displays, signal generators, SCR’s, opto isolators, photo diodes, semiconductors, motors etc.



LTSPICE by Linear Technology

Author : Linear Technology

Licence Type : Freeware

Size : 16.1 MB

LTSpice – is a widely popular SPICE simulator from Linear. LTspice is a free circuit simulation tool from Linear Technology corporation. This simulation software is considered as one of the best freeware available. Highlight of LTspice is much fast simulation of switching regulators with enhanced SPICE (compared to normal SPICE simulators).LTspice gives access to over 200 op amp models, transistor models, MOSFET models etc. A high disadvantage of LTspice is its proprietary code base which is licensed by Linear Technology.

From my experience, its good tool for power circuit analysis. Many engineers prefer using this tool.
