Server Availability Improvements

Feb 23 2014, 12:30 PM PST · 1 comment »

Earlier this month, we completed long-awaited improvements to the CircuitLab server infrastructure. As CircuitLab has grown to be used by tens of thousands of engineers, hobbyists, and students every workweek, we've faced normal "growing pains" in our ability to keep the site up and working fast for you. Unfortunately, that led to brief intermittent outages or sluggishness for our customers, especially in the December and January timeframe.

Our team targeted the critical areas causing these issues, re-engineering several of our server-side systems. In the past two weeks since we've deployed our improved back-end infrastructure, our site availability and performance are markedly better. We've also improved our monitoring systems that will allow us to more easily detect and solve these issues faster in the future. Thanks to all of our customers for your patience as we grow!


Expanded Device Library

Oct 26 2013, 3:00 PM PDT · 1 comment »

We've added over 100 new device models across MOSFETs, BJTs, diodes, and op-amps to make it easier for you to simulate your designs!

Just double-click on any component within the CircuitLab editor to use one of our standard library models, or create your own models from numerical parameters or from SPICE.


Custom Device Models and SPICE import!

Up until now CircuitLab has had only a limited number of device models in its component library. While you all love our interface and simulations features, our #1 most requested feature has been a more extensive library of components. Today we are releasing the ability for you to save your own device models, and reuse those models later in your other designs.

We have also added the ability to import certain SPICE models for BJTs, MOSFETs, and Diodes directly into CircuitLab, and you can save those models to your personal library for reuse later.
