Analog FastSPICE (AFS) Platform

The world’s fastest nanometer circuit verification platform for analog, RF, mixed-signal, and custom digital circuits.

The Analog FastSPICE™ (AFS) Platform is the world’s fastest nanometer circuit verification platform for analog, RF, mixed-signal, and custom digital circuits. More than 120 companies use the AFS Platform for their toughest circuit verification challenges, including high-speed I/O, PLLs, ADCs/DACs, CMOS image sensors, RFICs, and embedded memory.

Foundry-certified to 10nm FinFET processes, the AFS Platform delivers nanometer SPICE accuracy 5x-10x faster than traditional SPICE and 2x-6x faster than parallel SPICE simulators.

For large circuits the AFS Platform delivers >10M-element capacity and the fastest mixed-signal simulation.

For silicon-accurate characterization it includes the industry's only comprehensive full-spectrum device noise analysis and a high-productivity Analog Characterization Environment—both of which deliver 5x-10x speedup over alternative approaches.

For embedded memory and other array-based circuits, AFS Mega delivers silicon-accurate simulation with >100M element capacity.

Analog FastSPICE (AFS) Platform

“The move to the 16-nm FinFET process with multiple patterning and new transistors requires new approaches for accurate memory IP verification. With Analog FastSPICE Mega, we can accurately characterize post-layout FinFET-based memory array.”

Suk Lee , Senior Director, Design Infrastructure Marketing Division, TSMC

“The AFS Platform is the only SPICE-accurate simulator capable of verifying lock and performance on a post-layout PLL. With AFS we can run PLL characterization overnight with better accuracy than a traditional SPICE simulator running for over a week – a huge productivity improvement. A recent 10GHz 4-phase PLL designed for a test chip in 65nm CMOS and verified with AFS operated entirely within spec”

William Walker, Sr Research Fellow, Fujitsu Laboratories of America

“Our integrated RF transceiver / baseband chipsets have stringent circuit verification requirements. We selected the AFS Platform because it delivers nanometer SPICE accuracy and has significantly improved the speed of simulations compared to a parallel SPICE simulator.”

Lon Christensen,General Manager, Spreadtrum Communications USA Inc

“Analog/RF block characterization in nanometer process technologies is a design limiter demanding increased accuracy, performance, and capacity from circuit simulators. AFS MCP delivers nanometer SPICE accuracy and allows us to characterize our analog/RF blocks up to 50x faster than single-core traditional SPICE simulators.”

Dr. Xingang Wang, Senior Manager, Skyworks Solutions

“With the Analog Characterization Environment it is very easy to setup, run, and analyze results of complex characterization nests, enabling silicon-accurate and high-productivity circuit characterization with 5x-10x speedup over alternative approaches.”
