A Much Spicier SPICE: Free And Fast Circuit Simulation For Mixed Analog And Digital

For circuit analysis, SPICE simulations have become a staple tool for engineers. QSPICE is an advanced iteration of the SPICE simulator that offers design engineers a unique combination of speed, reliability, and versatility. In a conversation with the minds behind QSPICE, Mike Engelhardt (creator of QSPICE and LTSPICE), and Jeff Strang (Qorvo’s General Manager of Power Management), we shed light on the significance and unique features of this simulator.

Strang emphasizes its groundbreaking mixed-signal simulation capabilities, catering to power engineers working on circuits that combine RF and digital elements. He also covers QSPICE's improved basics, including increased simulation speed and accuracy, detailed transistor models, and adaptive time-step control. Engelhardt sheds light on QSPICE's versatility, applicable across diverse fields, from AI algorithms for EV battery charging to pulsed-radar power supplies. The software's local run capability, air-gapped security, and lack of artificial limitations on circuit size or complexity enhance its appeal.

QSPICE is poised to redefine the landscape of circuit simulation, offering a faster, more efficient, and more comprehensive solution for the design community.
