Z-solver

Sometimes you just need quick answers from datasheet parameters and what-if topologies. Z-solver gives designers quick field solver results on impedance, differential impedance, insertion loss, and impacts from copper roughness for microstrip signals, buried microstrip signals and striplines using the time-tested HyperLynx field solver.

  • The most reasonably priced path to making tradeoffs between Dk, Df, trace topologies, and spacing.
  • Results include impedance, differential impedance, propagation delay, and loss vs. frequency.
  • PCB impedance and loss-planning tutorial.

Z-planner

Z-planner is a field-solver based PCB stackup planning and materials selection tool that’s optimized for hardware engineering teams—including just about everything you can think of for designing stackups, including a lossy field solver, an extensive dielectric library, and interfaces to popular signal integrity tools.

  • Solve for Zo, Zdiff, insertion loss, and propagation delay.
  • Generic stackup library and Stackup Wizard get you started quickly.
  • Industry leading accuracy and ease of use.
  • Stackup design and PCB material-selection tutorial.
  • Includes Z-solver.

PCB Materials

The Dielectric Materials Library provides a central administrative environment for managing and deploying qualified PCB laminate materials, including frequency-dependent Dk and Df for major high-speed PCB laminates right out of the box.

Industry-Leading Analysis:

The foundation for signal quality—and signal-integrity analysis—is the PCB stackup; and yet detailed design of the PCB stackup is often handled by the PCB fabricator late in the design and prototyping process, long after signal-integrity simulation and analysis should have taken place. Here are some of the patent-pending analysis features in Z-zero software:

  • Loss planning, including copper roughness — Layer by layer calculation of loss as a function of geometry, Df, copper roughness on both sides and frequency.
  • Automated tracking of glass-reinforcement pitch — for mitigating glass-weave skew (aka: fiber-weave effect).
  • Etch effects (aka: trapezoidal traces) — The ratio of the prepreg vs. the core side of a signal layer can be controlled across all stackups by default, or individual stackups.
  • Reference signals to non-adjacent planes for field-solver impedance calculations.
  • Detailed modeling of solder masks — Enabling increased accuracy in microstrip impedance calculations.
  • Show/edit Vias — Document via diameters and layer connectivity for fabrication, including aspect ratios.
  • Stackup DRC’s — Automatically detects errors, including symmetry violations, incorrect stackup sequencing, etc. in PCB stackups.
  • Propagation delay simulation — Automatic calculation of signal propagation delay. Results are available in both delay/inch, and total delay for a signal path.
  • Pressed prepreg thickness — Automatic adjustment of board and prepreg thickness due to prepreg flow in fabrication.
  • Multiple differential pairs — Unlimited named differential impedance calculations on any signal layer.
  • PCB stackup import/export utilities — for popular signal integrity software, enabling design reuse and more accurate simulation results.

Industry-Leading Ease of Use

Customizable project views, allowing each user to customize the fields, parameters, and preferences for working with PCB stackup design.

  • Stackup Wizard allows you to create a stackup of any thickness and layer count, enabling automated creation of generic stackups, or stackups based upon product or material-parameter searches of the dielectric materials library.
  • Excel export allows easy stackup documentation in a familiar, portable output format.
  • Unlimited named differential impedance calculations on any signal layer.
  • Customizable project views, allowing each user to customize the fields, parameters, and preferences for working with PCB stackup design.
  • Horizontal line of symmetry in the stackup can be turned on or off.
  • Core locking can be turned on or off—enabling you to copy/paste or drag and drop a core dielectric from the library together with associated copper layers.
