Cadence Introduces the Spectre X Simulator, a Massively Parallel Circuit Simulator Delivering Up to 10X Faster Simulation with the Same Golden Accuracy

The Spectre X simulator also delivers an increase in capacity of up
to 5X for today’s large, advanced-node designs

SAN JOSE, Calif.–(BUSINESS WIRE)–Cadence Design Systems, Inc. (NASDAQ: CDNS) today announced the Cadence®
Spectre® X Simulator, a massively parallel circuit simulator
designed to provide up to 10X performance gains, while maintaining the
golden accuracy customers have come to expect from 25 years of Spectre
industry leadership in analog, mixed-signal and RF applications. The new
Spectre X simulator can solve 5X larger designs when compared to
previous simulation solutions, enabling customers to effectively
simulate circuits containing millions of transistors and billions of
parasitics in a post-layout verification flow.

The new Spectre X simulator offers customers the following benefits:

  • Proven Accuracy: The Spectre X simulator delivers the same
    golden accuracy as previous generations of Spectre simulators, which
    analog designers have relied on for years. For users that want to
    trade off accuracy for performance, the Spectre X
    simulator provides a single control that lets users easily determine
    the right accuracy/performance tradeoff needed for their particular
  • Massively Distributed Simulation: The solution enables users to
    distribute time-domain and frequency-domain simulations on hundreds of
    CPUs and take advantage of the scalability of data center or cloud
  • Faster Runtime: Utilizing better numerical techniques and
    modern compute hardware, the Spectre X simulator offers up to 10X
    faster simulation on 5X larger designs without sacrificing accuracy.
  • Ease of Adoption: Built on the principles that have made the
    Spectre circuit simulator the industry gold standard, the Spectre X
    simulator uses the existing foundry-certified device models without
    modification. Additionally, the Spectre X simulator supports existing
    Spectre design flows such as the Cadence Virtuoso® ADE
    Product Suite, Virtuoso RF Solution, Legato Reliability
    Solution, and Liberate Characterization Suite.
  • Mixed-Signal Support: The Spectre X simulator is tightly
    integrated with the Cadence Xcelium Parallel Logic
    Simulation for mixed-signal verification using Spectre AMS Designer,
    providing full support for mixed-signal behavioral languages and real
    number modeling methodologies.

“The Spectre X Simulator marks the next generation of trusted simulators
from Cadence, providing customers with the accuracy and speed needed to
complete their designs efficiently to meet aggressive time-to-market
goals,” said Tom Beckley, Cadence senior vice president and general
manager, custom IC and PCB Group. “We have multiple customers already
using the Spectre X simulator, and they are experiencing excellent
results. With its massively parallel technology, faster runtime, and
greater capacity, it’s the ideal simulator for use on advanced-node,
analog, RF and mixed-signal designs.”


“Analog accuracy is of paramount importance for our high-precision
circuits, regardless of size and complexity. We have simulated our
advanced-node 5G designs with the Spectre X simulator and it shows up to
7X run-time improvement, even when factoring in large amounts of
parasitics in post-layout verification. This verification process will
result in improved yields and enhanced reliability for MediaTek’s
customers and consumers.”
Ching San Wu, General Manager,
Analog Design and Circuit Technology, MediaTek

“As a world-leading supplier of computer networking products using
InfiniBand and Ethernet technology, it is critical that we accurately
simulate advanced node designs fast to meet our aggressive
time-to-market schedule. Through our use of Spectre X simulator, we have
experienced up to 10x performance gain compared to our existing solution
while maintaining accuracy that Spectre simulators are known for.”

Yonatan Malkiman, VP, Advanced Solutions at Mellanox Technologies

“Analog verification is increasingly critical for our advanced designs
targeted for the automotive, industrial and broad-based industries.
We’ve participated in the early adoption program for the Spectre X
Simulator using several designs, and have seen up to 10X performance
gains with Spice-level accuracy. We look forward to using the Spectre X
Simulator for our production designs that require performance and
capacity improvements.”
– Nobuhiko Goto, Director of Design
Automation Department, Shared R&D Division 2, Broad-based Solution
Business Unit, Renesas Electronics Corporation

“Post-layout verification is critical for our analog designs. Our
designs require a simulator with SPICE-like accuracy, high performance
and very large capacity so we can simulate them with thousands of
parasitics. We evaluated several different vendors but chose the Spectre
X simulator because we routinely saw a 5X improvement in overall
simulation performance, saving us days of simulation time during our PLL
