E8885A Image

Note: Model number E8885A has been discontinued; however, the Convolution Simulator feature/capability is now included in the W2302 Transient Convolution Element.

The information below is provided for reference only.

E8885A Convolution Simulator is an advanced time-domain simulator that extends the capability of E8884A 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 to efficiently and accurately analyze transient circuit conditions while considering the full effects of all circuit components.

Product Highlights:

  • Transient Noise Simulation with a wider range of supported devices including all linear and nonlinear device models
  • Speed. The Transient simulator continues to improve in simulation speed
  • Effectively models off-chip elements and simulates chip to board interactions
  • Extends the capability of <> by including arbitrary frequency domain data files such as S-parameters
  • Swept variable analysis for determining optimum solutions
  • Time-to-frequency-domain transform allows RF designers to view results in the frequency domain
  • Platform Computing Load Sharing Facility (LSF) supports the following options:
    -Find the fastest available server and run
    -Run simultaneous simulations
    -Distributed Processing. Most efficient for sweeps that don't require the solution of the previous run
  • Variable Equations (VAREQN) variables may now be referenced in Measurement equations (MEASEQN) and Optimization/Yield/DOE (Design of Experiments) controllers
  • Measurement equations can access the contents of any existing dataset. This can be very useful in optimization and yield analysis where goals/specs can make direct reference to existing data. The data may be generated from a previous simulation, or from an external source such as another simulator, or an instrument
  • Advanced statistical design capability aids in optimizing performance and production yield. Capabilities include automatic normalization of sensitivity analysis output and optional run of final analysis after optimization run completion

Product Description:
Unlike High Frequency SPICE, the Convolution Simulator can also simulate circuits that contain components characterized with measured S-parameter data.
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 allows RF designers to view results in the frequency domain when desired.

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.
