Circuit Simulation & PCB Design Tools

In the fast-paced world of electronics design, having the right tools at your fingertips can make all the difference between a concept that stays on paper and one that comes to life. Whether you’re just starting out or you’re a seasoned pro, circuit simulation and PCB design software help you prototype, test, and refine your ideas before you ever send files off for fabrication. Below is a curated roundup of both free and professional-grade applications, complete with links and brief descriptions, so you can quickly find the right fit for your next project.

Free Circuit Simulators:

• Tinkercad
  Free, easy-to-use app for 3D design, electronics, and coding.
  
  
• CRUMB: Circuit Simulator
  Educational circuit simulation.
  
  
• Falstad
  Electronic circuit simulator with animated schematic visualization.
  
  
• Qucs project: Quite Universal Circuit Simulator
  Integrated circuit simulator for large-signal, small-signal and noise behaviour simulation.
  
  
• EveryCircuit
  Interactive circuit simulation
  
  
• CircuitLab
  Online circuit simulation and analysis
  
  

Professional Tools:

• LTspice
  Powerful, fast, and free SPICE simulator software with enhancements for analog circuits
  
  
• TINA-TI Simulation tool
  Provides conventional DC, transient and frequency domain analysis with extensive post-processing capability
  
  
• PCB Design and Circuit Simulator Software - Proteus
  PCB Design and Circuit Simulator Software combining schematic capture, advanced simulation, and PCB autorouting:
  
  
• Altium Designer - PCB Design Software
  Complete solution for PCB projects with advanced routing and 3D surface design

No matter which tool you choose, the key is to dive in and experiment: run simulations, tweak parameters, and layout a PCB to see how it behaves in the real world. As you explore this list, you’ll discover that each software has its own strengths; whether it’s lightning-fast SPICE analysis, interactive waveform displays, or advanced routing features. Feel free to share your experiences, favorite tips, or any hidden gems you uncover. 

Happy Designing!

What To Do If You Are Being Cyber Stalked - How To Deal With Cyberstalking

Steps to Take if You Are Being Cyber Stalked

Does Your Device Support Wifi6 or Wifi6E

 

In this post we’ll give you a quick, jargon-free way to tell whether your current phone, laptop, desktop motherboard or router is likely to support Wi-Fi 6 or 6E, and what to do if it doesn’t. No deep dive into radio theory, just practical timelines, and some viable Wi-Fi upgrade options.

AI-Washing: 

The Potential Dot.Com Bubble Dejavu...

Artificial intelligence is transforming software, but the gold-rush mentality around “AI-powered” everything has begun to look (and behave) like the dot-com bubble. Below is a concise look at the evidence, the warning signs, and what real AI work actually entails.

AI Mechanistic Interpretability

AI Mechanistic Interpretability: Why Understanding AI is Just as Important as Building It

AI is no longer just a tech race, it’s turning into an arms race. We like to think we’re teaching AI, but in many ways, we’re struggling to keep up with what AI is teaching us. As AI systems grow more powerful, we’re granting them enormous levels of trust and control; sometimes without fully understanding how they work.

And that’s a problem.

Allow a Blank User Password for Scheduled Tasks

To allow blank passwords for a scheduled task in Windows 11, you need to disable a security setting in the registry. A simple Windows Registry key controls whether blank passwords can be used for local account logins, including scheduled tasks. By disabling this setting, you can allow the scheduled task to run without a password!
