2019 HF4 Release for Clarity, Celsius, and Sigrity Tools Now Available

The 2019 HF4 production release for Clarity, Celsius, and Sigrity tools is now available for download at Cadence Downloads. For the list of CCRs fixed in the 2019 HF4 release, see the README.txt file in the installation hierarchy.

SIGRITY2019 HF4

Here is a list of some of the key updates in the 2019 HF4 production release for Clarity, Celsius, and Sigrity tools. For more details about these and all the other new and enhanced features introduced in this release, see What's New in Sigrity 2019 HF4.

Clarity 3D Solver 

  • Enhanced Far Field Processing Capability: The far field processing capability in Clarity 3D Workbench has been enhanced further. For example, you can now plot several parameters such as Voltage Standing Wave Ratio (VSWR), Front to Back Ratio, Right-Handed Circular Polarization Ratio (RHCP), Left-Handed Circular Polarization Ratio (LHCP), PHI Polarization Ratio, and THETA Polarization Ratio. In addition, new options have been added in the FarFieldOptions dialog box to control the display of the 3D far field pattern.
  • Support to Run Clarity Simulations from the Command Line: A new command, clarity_bsub, has been added that enables you to run a Clarity 3D Layout or a Clarity 3D Workbench simulation directly from the command line. The clarity_bsub command is located in the <installation>/tools.lnx86/bin directory.
  • Support for S Parameters Added in Multi-terminal Circuits: To model passive circuits, Clarity 3D Layout now supports the keyword S in multi-terminal circuits.
  • Performance Improvements for DC Solution: Performance of DC solution has been improved.

For detailed information, refer to Clarity 3D Layout User Guide and Clarity 3D Workbench User Guide on the Cadence Support portal.

Celsius Thermal Solver

  • Power Map Import Enhancements: You can now import 2D power map files in Celsius Solid Objects Simulation for 3D Structures and Celsius Fluid Flow Simulation modules. You have the option to import tile-based, as well as, area-based power map files. While importing the power map file, you can preview how the power values map to the corresponding data points in the design. You can also preview how an object would appear when flipped or rotated.
  • Support for Specifying Flow Resistance in Celsius Fluid Flow Simulation: The Celsius Fluid Flow Simulation module lets you simulate porous regions by assigning a flow resistance to the selected regions. This porous media simplification helps in reducing the complexity of the mesh and saving the simulation time. You can specify the 2D flow resistance to 2D planes and 3D flow resistance to 3D objects. You can also calculate the 2D flow resistance for the chassis walls.
  • Support for Compact Heat Sink Models: You can now create compact heat sink models in Celsius. In compact heat sink models, the fin area is modeled using the thermal resistance and flow resistance instead of individual fins. Celsius allows you to specify the thermal resistance as a single value or a thermal resistance versus flow speed curve.
  • Support for Defining Thermal Contact Resistance in Celsius Solid Objects Simulation for 3D Structures: The thermal contact resistance between surfaces (solid-to-solid) can now be defined using the Celsius Solid Objects Simulation for 3D Structures module. This improves the accuracy of thermal simulations.

For detailed information, refer to Celsius Thermal Solver User Guide on the Cadence Support portal.

Migration of SystemSI from Sigrity User Interface to Allegro User Interface in Future Sigrity Releases

This is an early notification for the existing users of SystemSI. In the upcoming Sigrity 2021.1 base release, support for the current version of SystemSI will be discontinued from the Sigrity user interface because the new SystemSI has migrated to the Allegro user interface. Plan a migration to the new scheme that necessitates installation of the latest OrCAD/Allegro 17.4 (SPB174) HotFix and Sigrity 2021.1 releases from https://downloads.cadence.com. On Windows, open the new SystemSI tool from the Cadence System Analysis folder on the Start menu.
