History

Founded by Dr Ivan Pesic (September 13, 1951, Resnik, Montenegro — October 20, 2012, Japan) in 1984, the company is privately held and internally funded. It is headquartered in Santa Clara, California, with eight offices worldwide including US offices in Austin, Texas; North Chelmsford, Massachusetts; and Phoenix, Arizona.

In 2003 Silvaco acquired EDA Pioneer Simucad, for its brand name as well as for its SILOS and Hyperfault simulators. Simucad was one of the oldest companies in the IC design industry. The original Simucad was formed in 1981 with pioneering business in Verilog simulation. It was acquired by HHB Systems, which in its turn was acquired by Daisy Systems in 1980s and in the early 1990s Simucad was spun off as a management buyout. After purchasing Simucad in 2003 Silvaco re-launched the brand by spinning out its EDA product line in 2006 under the Simucad name. Simucad acquired ownership all of Silvaco's simulation and CAD products and intellectual property, most notably the SmartSpice circuit simulator. As of March 1, 2010, Simucad Design Automation and Silvaco Data Systems were merged back together forming Silvaco, Inc.

In 2012 David Halliday was appointed CEO after Ivan Pesic the company founder died from cancer. David Halliday joined Silvaco in 1992 and prior to his appointment as CEO he was the company COO. David also held the office of Vice President of Engineering for much of his tenure at Silvaco.

In 2015, Silvaco announced a new CEO, David Dutton. The company also announced its entry into the power integrity signoff market via the acquisition of Invarian.

Victory Stress is a generic 3D stress simulator designed to calculate stresses and mobility enhancement factors for any 3D structure using comprehensive material stress models.

Other tools

Interactive Tools, a suite of pre and post processing tools that provide interactive GUI-based pre and post processing services to Silvaco’s 1D, 2D and 3D TCAD simulators.

Virtual Wafer Fab or "VWF" is a group of TCAD products that automate and emulate physical wafer manufacturing. These tools facilitate the input, execution, run-time optimization, and results processing of TCAD simulations into a flow managed through a common database. It can be used for such tasks as designing more efficient solar cells for use in space.

EDA products

The company supplies integrated EDA software in the areas of Analog/Mixed-Signal/RF, Custom IC CAD, Interconnect Modeling, and Digital CAD.

Analog/Mixed-Signal/RF products

Utmost III SPICE modeling software generates SPICE models for analog, digital, mixed-signal, and RF applications.

Utmost IV optimization module provides a database-driven environment for the generation of SPICE models and macro-models for analog, mixed-signal and RF applications.

Spayn, meaning Statistical Parameter and Yield Analysis, is a statistical modeling tool for analyzing variances from model parameter extraction sequences, electrical test routines, and circuit test measurements.

Gateway is a schematic editor. It is a front end for Silvaco's Analog/Mixed Signal/RF IC Design Platform, and is integrated with the company's circuit simulation, layout, DRC/LVS/LPE, and parasitic extraction tools.

SmartSpice is an analog circuit simulator used in the design of analog circuits and analog mixed-signal circuits. It can analyze critical nets and characterize cell libraries.

SmartSpice RF is a harmonic balance based RF simulator. It provides a set of steady-state large-signal analyses and measurements to design GHz range RF ICs driven with multi-tone sources.

Such data files include schematic symbols, parameterized cells (PCells), DRC/LVS runsets, parasitic extraction runsets, and scripts to automate the generation and verification of design data.

Foundry process-specific models, symbols, and rule decks are integrated and tested with Silvaco custom IC design tools and PCells to create an AMS/RF design environment.

Litigation

Silvaco has been involved in litigation against Circuit Semantics, Inc. (CSI), Technology Modeling Associates, MetaSoftware and Avanti Corporation for theft of trade secrets. Silvaco won a $20 million judgment from Avanti just prior to the latter company's acquisition by Synopsys. In 2008, legal action by Silvaco against Cypress Semiconductor, Inc. led the California Court of Appeal to make a ruling clarifying when the statute of limitations for theft of trade secrets begins. The ruling stated that "statute of limitations on a cause of action for misappropriation begins to run when the plaintiff has any reason to suspect that the third party knows or reasonably should know that the information is a trade secret."

In Silvaco Data Systems v. Intel Corp., Silvaco sued Intel for misappropriation of trade secrets (deriving from the CSI case), but ultimately lost in both the trial and appellate courts.
