Best software for block diagrams?

Click For Summary

Discussion Overview

The discussion revolves around the search for suitable software for creating block diagrams, particularly in the context of optics and transmission work. Participants explore various software options, including free and paid solutions, and consider their applicability to both presentation and simulation needs.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant seeks recommendations for software to create professional block diagrams, mentioning a preference for free options unless paid software offers significant advantages.
  • Another participant suggests Microsoft Visio for presentation purposes, while noting that Simulink is more focused on computation and simulation.
  • A participant expresses a lack of interest in running simulations, indicating a preference for lab work instead.
  • There is a suggestion that simulation can be more important than lab testing, although some participants express uncertainty about their ability to learn simulation tools.
  • A first-year PhD student shares their background in photonics and MATLAB, indicating a desire to learn more about simulation despite feeling it may be challenging.
  • Another participant encourages the student to check if their university provides access to Visio or to consider open-source alternatives, while also emphasizing the practical importance of simulation.
  • Concerns are raised about the compatibility of Visio with Mac operating systems, leading to a search for alternative software that works on Apple OS.

Areas of Agreement / Disagreement

Participants express differing views on the importance of simulation versus lab work, and there is no consensus on the best software for block diagrams. Multiple software options are discussed, but no single solution is universally agreed upon.

Contextual Notes

Participants mention various software tools and their functionalities, but there are limitations regarding specific software capabilities and compatibility with different operating systems. The discussion also reflects varying levels of experience and interest in simulation among participants.

Who May Find This Useful

This discussion may be useful for students and professionals in optics, photonics, or related fields looking for software solutions for block diagram creation and those interested in the balance between simulation and experimental work.

Hi - I need/want to create reasonably professional block diagrams and wondered if anyone knew of the best software to do this? Free is better than $$ unless the stuff you pay for is loads better.

We are not talking anything amazingly complicated here. I am doing some work with optics and transmission. So if I can stick in lasers, modulators, various types of amplifiers, different types of fiber and receivers etc that would be more than enough. Going forward

I have MATLAB and am told you can do this with simulink, but I have no idea how to do this and want to know if there is something better?

Thanks

are you trying to do anything with these block diagrams, or just present them?

Microsoft Visio is the perfect tool for presenting. Simulink is a computation/simulation tool that happens to present its data in a block diagram.

As things stand I have pretty much no interest in running simulations on a computer. My work is/should be done in a lab.

I'll have a look into Visio! Thanks.

Simulation is often more important than actual lab testing...

I get that. But I don't know how to do it. I'd love to know - but I have no idea.

However - I'll buy this: https://uk.mathworks.com/support/books/book120003.html and have a go at learning. I'm not sure I'm capable though.

Are you a student or a professional?
What type of work are you doing?
What level of education/experience do you have in the field?
 
I'm doing some work related to photonics. I'm a first-year phd student - and have used MATLAB a fair bit, but have never used simulink.

There are people in my office who do a fair amount of simulation type stuff. But I am not one of them. My PhD is meant to be more experimental than theoretical.

I think what I'm trying to do would be hard to simulate. But I don't know unless I learn a bit more about it.
 
Ok cool. So as a student hopefully your university should give you access to visio. If they do not, ask your professor to buy it for your department (or look for open source versions). baring that you can always use power point (for free with a college email! https://www.microsoft.com/en-us/education/students/default.aspx).

Simulation isn't theoretical, its actually very practical and can be crucial to actually do testing. You want to get a ballpark idea of what will happen, you don't want to just throw a switch and cross your fingers.

Matlab is a great tool for you to learn, although there may be software specific to what you are studying

Visio is generally the goto for process planning and block diagrams, but this is not included in the base Office packages - Review these options

Cheers - I use a macbook pro for most of my work. And I've found visio won't work on that. I could get it to run windows - but i don't want to do that so I'll have to find something that is happy with Apple OS. I have a windows based computer in my office. But am really not a fan of it.

I'll look into the options - and do the smart thing and ask my colleagues what they use! Cheers.
