GoldenGate 2012.10 (4.7) includes the following new and improved capabilities:

  • Full support for X-parameters* – Including new X-parameters (XP) generation capability in addition to XP simulation support. X-parameters enable designers to capture the nonlinear behavior of active components in a standard format. X-parameters also hide intellectual property while enabling fast, accurate simulation within GoldenGate, Advanced Design System (ADS) or SystemVue.
  • New AC Stability (ACSTAB) Analysis – ACSTAB provides simplified setup, analysis and results processing for Bode stability analysis using the Middlebrook technique. This allows open-loop gain and phase characteristics of a circuit to be determined while the loop remains closed. No changes to the schematic are required for this new analysis.
  • Improved Links to System-Level Simulation – Including enhancements to the Fast Circuit Envelope (FCE) model export from GoldenGate to SystemVue and the ability to export and evaluate Application Extension Language (AEL) expressions during Virtual Testbench (VTB) evaluation with Ptolemy.
  • Usability Enhancements – Includes a broad range of enhancements throughout the product.
  • Licensing Improvements and Enhancements - More robust license behavior with improved licensing logic. Easier license experience with new License Manager and Product Selector.


Keysight’s GoldenGate 2012.10 delivers new and enhanced capabilities that improve productivity and efficiency for RFIC designers.

Note: GoldenGate 2012.10 is a base product release (4.7.0) that includes all 4.7.x versions of GoldenGate.
