Maverick and Guardian – Enhancements

The latest release of Layout versus Schematic tools from CELEBRITY CAD suite (Maverick full-chip parametric netlist extractor and Guardian hierarchical netlist comparator) delivers a number of significant advances. The engines of both tools were tuned up to achieve essential reduction of running time while processing huge designs.

Design Version Control System for Expert

The DVCS subsystem of CELEBRITY CAD suite provides significant improvement in management of complex designs, design reuse and teamwork management. The most important features of DVCS are the means for version tracking and team design coordination.

Q. When I simulate my process flow the simulated profile is always lower than the SRP measurements. What could be causing this? A. In many simulated process flows the surface oxide is etched completely off after which there may be some diffusion cycles.

Using Luminous to Model the Transient Response of a Silicon Charge Collection and Transfer Structure

The rapid evolution of modern photonic devices in digital photographic and detection systems creates a need for physically-based simulation of charge collection and transfer. In this article we show the linearity, spatial sensitivity, and spectral response of a generalized silicon pixel structure using the Luminous module of the ATLAS device simulator.

Calibrated and Predictive Simulation of Doping Profiles: Low Energy As, B and BF2 Ion Implantation

This article will present an efficient and original methodology for global and predictive modeling of low energy Boron, BF2 and Arsenic ion implantation, in the suitable range for sub-100nm CMOS technology.

QUEST – Extraction of Frequency Dependent R, L, C, and G Transmission Line Models

A primary use of QUEST is intended to be for extracting frequency dependent transmission line models for use in SPICE circuit simulations. The generation of SPICE parameters for transmission line models is becoming increasingly important as clock speeds approach and exceed the 1 GHz frequency range.

Q. How can I extract VBIC bipolar model parameters using UTMOST III? A. UTMOST III Bipolar module can be utilized to extract and optimize the VBIC model parameters for bipolar devices.

NEW RF MOSFET Small Signal SPICE Model

With the advent of ever increasing operation frequencies, Silvaco is introducing a new high frequency model for MOSFETs that will be implemented into the SmartSpice code. This article describing these new models will be in two parts.

JFET/MESFET TRIQUINT Models (Level=5 and level=7)

Until now, SmartSpice has supported the TriQuint model designated TOM using the Level=5 model parameter. SmartSpice now supports the TriQuint-2 MESFET model designated TOM-2. This model is accessible as a standard MESFET model, using the Level=7 model parameter. It is an incremental improvement based on TriQuint?s original MESFET model. All current analyses are currently supported (dc, ac, transient and noise).

New Version 5.0 of UFSOI Model Released in SmartSpice

The University of Florida SOI Group first released version 5.0 of UFSOI model in August 1999 and then in November 1999. To keep backward compatibility with previous versions, two model parameters (VERSION, REVISION) have been added in SmartSpice to select the desired model. By default, the value of VERSION is 5.0 and the value of REVISION is 1.0 which corresponds to the last release of November, 1999.
