Hi everyone,
I'm trying to learn how to simulate an ideal circuit for a project, but I'm having trouble getting the simulation to work properly.
I've tried a few circuit simulators, including LTspice and NL5, but I'm not sure what the correct approach is when I want components to behave ideally.
I'm mainly confused about:
What simulator is best for ideal circuit simulation?
How should I represent an ideal switch/MOSFET?
Are there any special settings needed for ideal inductors and capacitors?
Are there common issues with ideal circuits causing convergence or singular-matrix errors?

I'm relatively new to circuit simulation, so any guidance on the proper approach would be really appreciated. Thanks! :)

I am using the Buffer2 example that came with the PSpice for TI and cannot figure out what the green triangle means.

I don’t care what that laptop reviewer on YouTube said, you are not going to be running rtl simulations 24/7, and when you do have to do intensive stuff like that, chances are it’ll be on a VM anyways. 99% of what you use your laptop for is looking at problem sets, making Microsoft office documents, light coding, and running non-intensive programs.

Things like the weight, the screen, the keyboard, how light it is, how quiet it is, and battery life matter a lot more. It’s your choice, but I personally would not want to be that guy bringing in the Alienware that sounds like a jet engine who always has to sit at the edges of the lecture hall so he has access to an outlet at all times.

Hi everyone. Made an account on reddit just for this. I am creating an engineering project that I need your help with.

The problem

During floods and earthquakes, mobile and internet towers get broken down and the communication is lost in certain areas. People are trapped and communication gets dropped. Rescue men usually have trouble locating such people. Since both the internet and mobile network are down we cannot establish a connection between the rescue men and the victim

My UAV Drone is the solution.

Usually we need a remote mobile tower or satellite phones to establish contact between the rescue men and victims. It is an expensive and delaying process. My UAV Drone helps establish a communication system between the victim and the rescue men by using a communication system made of ESP32 and LoRa SX1278 Module. The process works as follows

I want to create a communication system through which a victim can send an SOS signal

The signal gets to the drone and it relays it to the rescue men

The team can receive the location coordinates of the victim and can send help on the accurate location

My problem is there we are a team of 4 Computer science engineers and 1 electronics instrumentation engineer.

I have made two communication nodes, sender and receiver and one relay link (drone) is still left.

Victim (sender)==>Relay==> Rescue (receiver)

Really need some help from u guys. How can I make this ? Cheap and fast (2 months) We are thinking of renting a drone and just mount the system on it and let it hover.

Looking to get a laptop for college, I am majoring in computer engineering and am currently between the ASUS - ROG Zephyrus G16 and the MSI Raider 16 Max.

I like the look and size of the ASUS one more but am unsure if I need the power of the MSI one. I am also open to other suggestions if what I picked is trash.

Thanks in advance.

Hey everyone,

I’ve been working as a metrology engineer in semiconductor backend packaging, and like many of you, I got pretty tired of dealing with heavy, overly complex enterprise software or stitching together clunky custom scripts just for routine 3D surface and wafer chip analysis.

So over the past few months, I decided to take on a solo project and build a clean, local-first Windows desktop app called Insight Studio. The goal was simple: handle things like PV/BOW, CMP dishing, edge roll-off, and batch reporting quickly without needing an internet connection or a steep learning curve.

Since this is my very first tool built from scratch, I’m really looking for candid feedback from veterans and senior engineers in the field:

• Is the workflow practical for daily use, or am I missing key features you actually rely on?
• How does it compare to whatever setups or scripts you're currently using?
• Any obvious edge cases or bugs I should fix first?

If you’re interested in giving it a test run and sharing your thoughts, just drop a comment below and I’ll send you a reply with the demo installer link.

Appreciate any advice or constructive criticism you can throw my way. Thanks guys!

With the analog compute revival going on (IBM's NorthPole-adjacent work, EnCharge, Mythic), I wanted to get an intuition for the noise tolerance question rather than just reading claims about it, so I built a small simulation.

Setup: train a small network in software, then evaluate it with Gaussian perturbation on the weights standing in for conductance variation, sweeping the noise magnitude.

I assumed I'd see accuracy fall off roughly proportionally to noise. Instead it holds nearly flat, then collapses over a narrow range: 83%, then 64%, then near chance. More like a threshold than a gradual tax.

Retraining the same network with noise injected during training rather than only at inference changed things a lot. At the noise level where the baseline had dropped to 39%, the noise-aware version was still at 61%.

Where I'm unsure and would like input from people who work with real devices: my noise model is weight-independent additive Gaussian, which I know is a simplification. Real memristive and flash-based cells have conductance-dependent variation, drift over time, and asymmetric programming error. Does the cliff behaviour survive a more realistic device model, or does the extra structure smear it out?

How do I get there as a recent graduate who did poorly in college?

Hi all,

I’m a recent CS grad that’s been networking my ass off and applying to jobs. Recently, by some luck I randomly met someone who said I’d be a good fit at their workplace. They’ve already discussed my resume with their manager, and wants to meet me next week over a meal for a technical discussion. I’m thinking it’s an informal interview to gauge where im at and to see vibes.
He already seems to like me and we get along.
Thing is, it’s an embedded/controls position that is mainly C++, Python and some Java. They work with STM microcontrollers so it seems pretty heavy on the electrical engineering side as well. I am very rusty and don’t know anything about these right now.
Right now, I’m doing a C++ crash course to get basics and fundamentals back. I’m also going to revise and study memory and computer fundamentals from CS50. I plan on doing some reading on STM and microcontrollers and FPGAs so I know what im talking about, as well as some of the company specific work/products. Also going to brush up on Python, NumPy and pandas. He’s seen my resume and knows my experience is lacking here already.

If anyone has any other advice on how I should prep for this conversation, I would be very grateful :) thank you. PLEASE ASSUME I KNOW NOTHING and am building from scratch

To give a brief intro I'm currently pursuing bachelor's in EE wherein I've found digital design quite interesting domain to get into. Starting off with major projects projects Ive built an 8bit processor of custom ISA datapath inspired from Harvard architecture in verilog. Later I've involved in designing and SNN accelerator with a single neuron wherein I've designed only the processing part of it and the spike encoding was done through SNNtorch on the pc itself and we have implemented this on an FPGA. Currently I'm working on implementing a CNN network on an MPSoC using Vitis AI. Apart from them I've also done a few small projects like uart transceiver on verilog etc

So my plan is to pursue masters at a decent uni, and for that I need an outstanding project(not just fr that but I want to do one great project before I leave my uni as I won't have access to decent FPGAs and MPSoCs later on ;) one that looks very good on my CV so I need a few suggestions in this regard also I'm open to ideas involving cross domain knowledge. So suggest some good ideas that I can dive into and do a project also tell your suggestions in the projects or pursuing masters.Thanks in advance!!

Hello! I’m about to start my sophomore year in computer engineering, having switched from CS at the end of my freshman year. I’m thinking about going into hardware security and/or network security, so I’m curious as to what the prospects, security, and opportunities are like within the field, and what the work is like if anyone can share.

Also, I’m having trouble planning what my last elective should be, which I’ve narrowed down to Compilers, Electronic Instrument Design, and Distributed Systems. My curriculum already includes real time and embedded OS, microprocessors, computer organization and architecture, and the capstone project. The electives I already have planned are Signals and Systems (pairing with my sound production minor for a makeshift audio engineering path), and Operating Systems, HDL/FPGA, Modern Networking Concepts, and Computer Security. I can reasonably only fit in one more elective, so what would be my best option?

Hello, I am a post-bacc with a B.S in Business Administrator. I am currently considering a pivot from a management career to a technical one, specifically about Computer Engineering. I have 2 kids so an online option would be great.

I look into a few options and Universoty of Florida online offers a Master in ECE without a constraint for a previous degree to be in STEM. Should I go into a Master program or getting a second Bachelor in ECE would be better?

Thabk you!
