HILLSBORO, Ore. — October 10, 2024 — Wild River Technology (WRT), the leading supplier of signal integrity measurement and optimization test fixtures for high-speed channels at data rates of up to 224G, announced today the availability of a new advanced channel modeling solution that helps achieve extreme signal integrity design to 70GHz.

The solution is available both in a standard configuration and as a custom solution for customer-specific stack-ups and fabrication. The primary target application is to support a 3D EM solver analysis modeling versus time and frequency domain measurement methodology.

The solution contains:

  • The CMP-70 platform, assembled and 100% TDR NIST traceable tested, with custom stands
  • Material Identification overview web-based meeting including anisotropic 3D material identification
  • A cross-section PCB report and structures for using as-fabricated geometries
  • Measured S-parameters, pre-tested for quality (passivity/causality and resampled for time domain simulations)
  • A host of novel crosstalk structures suited for 112G HD level project analysis
  • PCB layout design files (NDA required)
  • An EDA starter library including loss models with industry-first accurate surface roughness models
  • Comprehensive training available for 3D EM analysis – correspondence, material ID in X-Y and Z axis for a host of EDA tools

The CMP-70 delivers a complete advanced channel modeling solution

The CMP-70 program continues the industry-first simulation-to-measurement collaboration with Cadence Design Systems that was initially established with the CMP-50. Significant resources were dedicated to the development of the CMP-70 by Cadence and Wild River over almost three years. At the recent DesignCon event, the CMP-70 was used in the Cadence booth to benchmark the Cadence Clarity 3D Solver.

The WRT application package also includes an industry-first modified Hausdorff distance (MHD) technique, included as Matlab code. This algorithmic approach provides an accurate way to compare two sets of measurements in multi-dimensional space to determine how well they match. The technique is used to compare the results simulated by Cadence Clarity with those measured on the CMP-70 platform. The methodology and initial results are shown in the figure below, where the figure of merit (FOM) is calculated from 10, 35, and finally to 50GHz. The MHD algorithm requires a Matlab license, but WRT also accommodates customer data as another option, where WRT provides the comparison between measured and simulated data.

Application of modified Hausdorff technique

“I am not a fan of hype-based programs that simply get attention,” remarked Alfred P. Neves, Wild River Technology’s co-founder and chief technical officer. “Both Cadence and Wild River brought substantial skills to the table in this project as we continued our industry-first simulation-to-measurement collaboration. The result is a proven, robust and accurate platform that brings extreme signal integrity to 70GHz designs. This application package has also been instrumental in demonstrating the robust 3D EM simulation capability of Cadence Clarity.”
