Silvaco Announces Viola I0-X – 10X Faster I/O Pad Characterization for Nanometer Silicon

SANTA CLARA, Calif.–(BUSINESS WIRE)–Silvaco Inc., a leading global provider of software, IP and services for
designing chips and electronic systems for semiconductor companies,
today announced Viola I0-X, a scalable semiconductor intellectual
property (IP) characterization and modeling tool and the latest addition
to the Silvaco Foundation IP product line.

By leveraging new Intelligent Optimization delivering 10X faster
performance (I0-X) and embedding Silvaco’s SmartSpice simulator and
Jivaro-A reduction technology, the fully automated Viola I0-X flow
delivers accurate models and faster turnaround time, setting a new
standard in Input/Output (I/O) Pad circuitry characterization and
modeling for designs targeted at nanometer process nodes.

Viola I0-X is an advanced characterization system that automatically
performs static structural analysis on transistor-level netlists of
standard cells and complex custom cells or macros. It uses the results
of this analysis to set up complete characterization constraints and
then leverages the foundry-certified, highly accurate and accelerated
SmartSpice simulator to increase the overall throughput of timing,
power, noise and statistical static timing analysis (SSTA) model
generation. Viola I0-X not only offers faster I/O pad characterization
capabilities, it supports all industry-standard model formats and
includes a closed-loop model validation flow that allows users to
seamlessly launch third-party to verify the generated models.

“Certus provides the most advanced solutions for optimizing area, power,
Electro-Static-Discharge (ESD) protection, features and performance of
I/O circuits,” said Stephen Fairbanks, Director at Certus Semiconductor.
“With Viola IO-X, we met the tight development and characterization
schedule for our client, a leading provider of IoT sensors. Its 10X
faster throughput makes no compromises in accuracy and enables
optimization of the area, power, and performance of I/O pad circuitry.”

“With Viola I0-X, I/O pad developers no longer need in-depth knowledge
of a circuit’s electrical operation to properly set up a
characterization run. Manual modeling efforts are eliminated which leads
to reduced delay in model development and excludes human errors,” said
Ole Christian Andersen, General Manager of the EDA Division at Silvaco.
“The technology in Viola I0-X extracts functionality, identifies all
electrical arcs, and optimizes the complete characterization methodology
for efficiency and accuracy, significantly reducing the time and effort
to model I/O pads and delivers 10X faster I/O Pad characterization
through the use of Silvaco’s Intelligent Optimization technology.”

Viola I0-X: Faster, More Reliable Model Sign-off

At the heart of Viola I0-X are Silvaco’s proprietary circuit functional
recognition, vector generation and SmartSpice simulation and Jivaro-A
reduction technologies . Each contributes to the ease of setup,
accelerated characterization throughput and quality of model sign-off in
Silvaco’s characterization solution:

  • Leveraging intelligent algorithms, Viola I0-X automatically recognizes
    and models the functionality of standard cells and generates an
    efficient vector set for all timing arcs. By eliminating
    time-consuming, manual analyses, Viola I0-X dramatically reduces the
    time required to set up and characterize I/O pads across a wide range
    of functional modes, process points, supply voltages and junction
    temperatures. The ability to efficiently handle the increasing number
    of process, voltage and temperature (PVT) points and operating modes
    is critical to nanometer design success.
  • Viola I0-X’s smart topology-driven vector generation features unique
    structure-based vector optimization and an intrinsic,
    simulation-induced constraint acceleration algorithm. These features
    eliminate vector redundancy and avoid unnecessary simulation while
    maintaining characterization accuracy. Viola I0-X also offers a
    flexible methodology, allowing the user to supply a vector set and its
    sequence for specific measurements.
  • Viola I0-X supports commercially available SPICE simulators, including
    Silvaco’s SmartSpice. When used in conjunction with SmartSpice, Viola
    I0-X’s optimized vector generation capabilities deliver an
    order-of-magnitude faster throughput than previous generations of
    Viola, without any loss of accuracy. SmartSpice is a full SPICE
    simulator in wide use by analog/mixed-signal designers, foundries and
    IP developers down to 5nm.
  • Jivaro-A is the industry-leading RC parasitic reduction technology for
    layout parasitic extraction (LPE). Its circuit optimization is based
    on accuracy requirements, stability of simulation, realistic values,
    reliability of analysis and verifiability. Jivaro-A is not a simple
    data crunching or filtering tool. Optimized for SPICE netlists, it
    reduces simulation time, increases accuracy compared to built-in
    reduction of circuit simulators and offers blazing fast processing.
