Key Inclusions:

  • Eye Diagram Analysis: Essential for determining if your PCIe signals meet the required standards for BER. The template uses the bathtub curve to determine the eye width and height at 1e-12 BER. Eye diagrams are crucial in identifying signal integrity issues.
  • Bathtub Curve Analysis: Provides detailed bathtub curves that evaluate signal integrity and eye height at various BER levels, helping ensure your design meets critical specifications. Bathtub curves give a comprehensive view of signal performance over time.
  • Signature Analysis: Helps identify and troubleshoot bad transitions, impedance changes, crosstalk, jitter, and other irregular signal phenomena. Each signature has a meaning and can highlight specific issues such as impedance mismatches or excessive jitter.
  • Equalization Parameters: These parameters are crucial for ensuring the PCIe lines maintain sufficient bandwidth. The template allows you to modify or remove equalization to study its effects. The ability to test with or without equalization helps in understanding the performance limits.
  • S-Parameters: The only input required is the S-parameters of a full/partial link. This significantly simplifies the setup process, enabling quicker analysis. The S-parameters define the electrical behavior of your PCIe channels.
  • Return Loss Analysis: PCIe specifies return loss, differential return loss, and common mode return loss. Each standard has its specifications extended to a frequency point. The template provides detailed plots for these parameters, helping ensure your designs meet all necessary standards.
  • Pre-Configured Test Setups: Multiple pre-configured test setups are embedded within the template, covering a range of PCIe compliance requirements. This includes eye diagrams, return loss, differential return loss, and common mode return loss, with all parameters and limits predefined for ease of use.

  • Automated Compliance Checks: The template automates various compliance checks, such as validating signal integrity, ensuring compliance with PCIe standards, and identifying any design flaws early in the process.

  • Comprehensive Simulation Capabilities: Supports advanced simulations including crosstalk analysis, jitter impact analysis, and power integrity studies. This helps in understanding the interplay between different signal integrity issues and how they affect overall performance.

  • Data Visualization: Advanced data visualization tools within HFSS allow for clear interpretation of results, making it easier to pinpoint areas of concern and optimize your design for better performance.
  • Integration with Other Tools: Seamlessly integrates with other Ansys tools, allowing for a holistic approach to design and analysis. This includes integration with SIwave for power integrity and EM simulation and with DesignerSI for system-level analysis.
  • Documentation and Reporting: The template includes features for generating comprehensive reports and documentation, which can be customized to include all relevant data and analysis results. This ensures all stakeholders have access to detailed insights into the design process.
  • Return Loss Analysis: PCIe specifies return loss, differential return loss, and common mode return loss. Each standard has its specifications extended to a frequency point. The template provides detailed plots for these parameters, helping ensure your designs meet all necessary standards.
  • Group Delay Analysis: Understand the delay between lines by calculating the skew based on the group delay of the differential mode. This is crucial for maintaining signal integrity across the PCB.
  • Advanced HFSS Capabilities: Includes options for adding random/continuous/discontinuous jitter or noise and supports advanced eye width analysis. Users can study the eye width of the signal under traces and make adjustments as needed.
