Ключевые возможности и технические характеристики

The Transient Simulator and Broadband SPICE element contains:

  • Transient Simulator (High Frequency SPICE) for RF and microwave application such as phase-locked loops and also for power electronics and power integrity (See the note below if you have signal integrity and/or power-aware signal integrity applications).
  • Support for native ADS netlist dialect, plus compatibility modes for netlists in other dialects: classic SPICE by UC Berkeley, Spectre and PSPICE by Cadence, HSPICE by Synopsys, and LTspice by Analog Devices.
  • Our patented Rao Convolution engine creates causal and (optionally) passive time-domain models from frequency-domain models. Such models typically come from EM field solvers such as ADS Momentum and EMPro FEM or from S-parameters from a VNA or third-party EM tool. Unlike other tools, ADS Convolution correctly handles challenging cases such a long or lossy transmission lines.
  • Broadband SPICE Model Generator, which lets you convert measured or simulated S-parameter models to lumped equivalent circuit or pole-zero (rational function) representations for use in third-party SPICE simulators.

IMPORTANT NOTE

A related element, the W2302EP/ET Transient Convolution + Channel Sim, has the Channel Simulator in addition to everything that W2310EP/ET Transient Simulator and Broadband SPICE contains.

If your application is RF/microwave, power electronics, or power integrity we recommend the W2310EP/ET Transient Simulator and Broadband SPICE element. However, if your application is signal integrity and power-aware signal integrity, we recommend the W2302EP/ET Transient Convolution + Channel Sim. If you have a mixture of these applications, obviously the superset product W2302EP/ET Transient Convolution + Channel Sim covers them all.

Описание

Our version of the classic SPICE simulator has been fine-tuned over many years for high-speed and high-frequency applications.

The Convolution engine is an advanced time-domain simulator that extends the capability of High Frequency SPICE by accurately simulating frequency-dependent components (distributed elements, S-parameter data files, transmission lines, etc.) in a time-domain simulator.

Designers can use Convolution along with Momentum to efficiently and accurately analyze transient circuit conditions while considering the full effects of all circuit components, including an EM-based model of distributed parasitics from the PCB traces.

Convolution Pulse Response

Convolution Simulator extends High-Frequency SPICE by allowing it to simulate circuits that contain components characterized with measured S-parameter data. The Convolution Simulator evaluates high-frequency effects such as skin effect, dispersion, and higher frequency loss. Typical examples include analyzing transient conditions where the effects of dispersion and discontinuities are significant, and observing the effects of off-chip elements, and chip-to-board interactions in IC simulations.

A time-to-frequency-domain transform is included. This feature enables RF designers to view results in the frequency domain when desired.

The Convolution Simulator can also produce transient, nonlinear analyses with respect to optional swept variables.

Voltage, current and user defined measurements can be manipulated mathematically using built in post processing.
 

Convolution allows accurate distributed models in transient simulation

The High-Frequency SPICE simulator is a non-linear, time-domain simulator for analyzing very large base-band circuits, startup transients, oscillators, and high-speed digital and switching circuits.

High-Frequency SPICE's ability to find a time-domain solution, for even the most complicated problems, makes it the most flexible type of non-linear simulator. Circuits with thousands of transistors can be effectively analyzed with this technology.

RFIC Oscillator Transient Simulation

At lower speeds, SPICE allowed designers to perform simulations using lumped-element models. But at today’s RF & microwave carrier frequencies and multigigabit per second chip-to-chip data rates, high-frequency and distributed effects such as impedance mismatch, reflections, crosstalk, skin effect, and dielectric loss come into play.

Ordinary SPICE simulators hit the "microwave wall." In contrast, the Advanced Design System (ADS) Transient Simulator accommodates not only lumped-element models, but also the distributed transmission line, S-parameter, and EM models that are essential to surmount the microwave wall. Our Transient simulator is unique in that it is not simply a high performance point tool, but a set of capabilities integrated into the ADS platform. You can combine system-, circuit-, or EM-level models – each at the appropriate level of abstraction – into one simulation.

Multicore processor support and a new, high-capacity sparse matrix solver achieve a three-fold simulation speed improvement for traditional transient simulations and make this the industry's fastest signal integrity circuit simulator.

High-Frequency SPICE is ideally suited to time-domain analysis of large high-frequency RF circuits with thousands of transistors. It is used to analyze the steady-state response of mixers, oscillators, amplifiers, and other circuits.

The simulator is also used to verify transient behavior, such as start-up times in oscillators, filter step function responses, pulsed RF network responses, high speed digital and switching circuits, and more.

High-Frequency SPICE offers all the regular features of SPICE transient analysis, plus improved convergence for large circuits, and additional features such as DC back-annotation to the schematic.
