CircuitLogix supports analog, digital, and mixed-signal circuits, and its SPICE simulation gives accurate real-world results. The graphic user interface allows students to quickly and easily draw, modify and combine analog and digital circuit diagrams. CircuitLogix was first launched in 2005, and its popularity has grown quickly since that time.
SPICE [5] is the origin of most modern electronic circuit simulators, its successors are widely used in the electronics community. Xspice [6] is an extension to Spice3 that provides additional C language code models to support analog behavioral modeling and co-simulation of digital components through a fast event-driven algorithm.

The Gummel–Poon model and modern variants of it are widely used in popular circuit simulators such as SPICE. A significant effect that the Gummel–Poon model accounts for is the variation of the transistor β F {\displaystyle \beta _{\text{F}}} and β R {\displaystyle \beta _{\text{R}}} values with the direct current level.
Accused UnitedHealthcare CEO killer Luigi Mangione spent his first night back in the Big Apple under the same NYC federal prison as disgraced rap mogul Sean "Diddy" Combs.
A report on proposed changes to U.S. dietary guidelines suggests encouraging Americans to eat more beans and lentils for protein and less red meat.
