SIGRITY/SYSANLS 2021.1 HF3

Here is a list of some of the key updates in the SIGRITY/SYSANLS 2021.1 HF3 release:

Note: The release announcement blog aims to list only the most important features implemented for the Systems Analysis and Sigrity products and does not cover all the features of the release. In order to see the complete list of the implemented features, refer to the following document: Sigrity Release Overview and Common Tools What's New.

Systems Analysis 2021.1 HF3

Clarity 3D Solver

• New Meshing Algorithm Introduced: Both Clarity 3D Layout and Clarity 3D Workbench now support a new massively distributed meshing algorithm, XMesh. XMesh is a domain decomposition technology that is applied during the initial mesh generation stage and provides significant performance improvement.
• Ability to Launch Clarity 3D Workbench from Clarity 3D Layout: A new option Launch Clarity3DWorkbench has been added in the Tools menu of Clarity 3D Layout. It enables you to launch Clarity 3D Workbench directly from Clarity 3D Layout. This option is useful for cases where you have to import multiple Clarity 3D Layout databases and merge them with other Clarity 3D Workbench structures.
• Basis Function Order Option Enhanced: A new value, MIXED FS, has been added to the Basis Function Order option in both Clarity 3D Layout and Clarity 3D Workbench. When you select this option, both Clarity 3D Layout and Clarity 3D Workbench use the ZERO and FIRST order elements together in the frequency sweep stage to reduce the memory consumption while providing almost the same accuracy as the FIRST order.
• Clarity 3D Spatial Mode Workflow Enhanced: The Spatial mode flow in both Clarity 3D Layout and Clarity 3D Workbench has been enhanced such that the near and far-field outputs now include the effects of the input pulse/pwl source excitation. The spectral content that is generated for the pulse/pwl source is solved using the discrete frequency sweep and the fields and mesh are saved at these frequency points.
• Backdrill Capability Enhanced: The backdrill capability of Clarity 3D Layout has been enhanced in this release. In earlier releases, when a design with backdrill information was imported into Clarity 3D Layout, the original via/layout information was lost during translation and there was no way to retrieve the lost information. In this release, a new option, Create backdrill hole by design has been added in the Translation tab of the Options dialog box, which when disabled, keeps all the via segments during translation. The Backdrill Editing dialog box has also been enhanced to dynamically update the backdrill/via diagram when the backdrill parameters are changed.

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

Celsius Thermal Solver

• Support for Liquid Cooling: You can now set up a liquid cooling system in the Fluid Flow Simulation module using cold plates, pumps, inlets, and outlets. Liquid cooling is a closed-loop system in which a coolant material runs through a cold plate and a pumping system to dissipate heat from the heat source. It provides higher cooling efficiency than air cooling due to higher specific heat capacity, density, and thermal conductivity of liquids.
• New Fluid Material Library: The Fluid Flow Simulation module now has a fluid material library that can be used to assign fluid materials for liquid cooling. You can either select one of the fluid materials available in the fluid material library or add a custom material to the library by defining the required material properties.
• Parameterization of Boundary Conditions and Material Properties: You can now set sweep parameters for boundary conditions and material properties. This allows you to study your design’s performance across a range of values for the given boundary condition or material property, without simulating the design multiple times, using different test values. The boundary conditions that support parameterization are: Static Power and Temperature, Heat Transfer Coefficient (HTC), and VRM/Sink Patch.
• Leakage Detection Checks: In Celsius Fluid Flow Simulation, you can run leakage detection checks on flow designs involving enclosed volumes. These checks help you identify any holes or gaps in the enclosed geometries that may cause fluid loss.
• Enhancements in Sink Current Source for Duration: In the Solid Objects Simulation for Layered Structures module, while specifying the time-dependent current for the sink, you can now use a current mapping file as input for Duration in transient analysis. Additionally, for unequal currents, a single mapping file can be used to input the current values.
• Support for Grid-based Thermal Analysis: In the Solid Objects Simulation for Layered Structures module, you can now view grid-based plane temperature results if the grid-based thermal mode is enabled. The Plane Temperature Results window displays the Layer Name, Grid ID, Metal Area (mm), Maximum Temperature (C), Actual Temperature (C), Grid Hotspot Coordinates (mm), and Ratio.

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

Sigrity 2021.1 HF3

Sigrity PowerDC 

• Multi-profile Bump/Solderball Support for a Single Component: PowerDC now supports the usage of multiple bumps/solderballs for a single component. This lets you define bumps/solderballs with varying sizes for the same IC component.

For detailed information, refer to PowerDC User Guide on the Cadence Support portal.

Sigrity SPEEDEM 

• Added to Layout Workbench: In this release, SPEEDEM has been added to the Layout Workbench, and the look-n-feel of the user interface has been enhanced. By default, SPEEDEM now uses a dark-themed interface.
• Postprocessing Migrated to SPEEDEM Generator: SPEEDEM Generator (SPDGEN) now supports the simulation and postprocessing functionalities, so you can analyze, compare, and print the 2D and 3D results of a time domain simulation. These functionalities were earlier supported by SPEEDEM Simulator (SPDSIM).

For detailed information, refer to SPEEDEM User Guide on the Cadence Support portal.

Sigrity Translators

• Support for OASIS to SPD File Translation: Sigrity Translators now supports the .oasis to .spd file translation. For this, a new executable Oasis2Spd has been introduced in this release. You can use it to translate OASIS files to SPD files, that can then be used by Sigrity products to provide the data, view and, output parameters for simulation.

For detailed information, refer to Translators User Guide on the Cadence Support portal.

Sigrity XcitePI

• Partial Lump Functionality Supported in XcitePI: The Partial Lump functionality is now supported for the following:
  • DIE IO and Interposer model extraction
  • Pin-Based and Net-Based model extraction
  • Output S-parameter and BBS model reduction
  • Partial lumped S-Parameter generation

For detailed information, refer to XcitePI User Guide on the Cadence Support portal.

Sigrity XtractIM

• Return Path Setup: In the Electrical Performance Assessment mode, you can now enable a fixed return path for Power – Ground Analysis. Selecting any of the enabled ground nets as the fixed return path helps you get a fixed RL value.

For detailed information, refer to XtractIM User Guide on the Cadence Support portal.
