LTE/ LTE-A Model Library Extended
Beginning with the June 2011 release customers of the LTE library gained access to the LTE-A(dvanced) enhancements that have been added to the library. No additional license key is required, all LTE-A capabilities come as a maintenance update to all LTE library licensees. The December release has seen further extensions of the LTE/LTE-A library, including end-to-end simulation systems for both uplink and downlink. End-to-end simulation systems include ideal receivers, but also complete MIMO Receiver models for general M x N MIMO configurations, featuring different algorithms, including Zero-Forcing (ZF), Minimum Mean-Squared Error (MMSE) Maximum Ratio Combining (MRC) and Maximum Likelihood (ML). For detailed information on the LTE-A features included in the LTE library product, read the datasheet.


Customer Success: Space Systems / Loral
The Simulation and Analysis team at Space Systems / Loral releases up to nine high-power satellites per year, all including signal processing receivers designed with SPW. Committed to delivering the highest performing satellite transceiver systems on a reliable schedule, the small development team needed an easy-to-use, effective design approach. SS / L selected Synopsys’ SPW tool, which they used to model, simulate and verify the algorithms for the satellite receivers. Read the complete Space Systems / Loral Success Story.


What's New in SPW and System Studio?
In December 2011, both SPW and System Studio have seen new releases.

SPW 2011.06-SP1 (December 2011), release notes available for download from SolvNet:
  • Design Editor improvements addressing descend performance, safe handling of invisible ports, rotated ports, expression warnings, and non-English font support.
  • Simulator improvements related to session level compiler flag, making basic/const mutable, multi-threaded simulation, and batch mode compilation.
  • Requirement for openmotif on Linux platform removed
  • Design Migrator enhanced for better handling of HDS designs
System Studio 2011.06-SP2 (December 2011), release notes available for download from SolvNet:
  • Additional compilers supported
    • Linux: GCC 4.5.2, both 32 and 64 bit version
    • Windows: you can now choose between the MSVC 8.0 and 9.0 compiler
  • Improved (library) build system
  • Revision control integration improvements
  • Improvements for integrating C++ code using std::string
  • Additional Tcl commands and built-in function

Events & Webinars

New Webinar: LTE-A Physical Layer Design: Downlink

In this webinar, we give an introduction to the LTE-A standard (Rel.10) with a focus on the downlink configuration, and explain the main enhancements over LTE Rel.8 and their implication on the overall system complexity. This is followed by an overview of Synopsys LTE-A library, a standard-compliant physical layer reference library verified in collaboration with Rohde & Schwarz. This overview will include some typical customer use cases. With LTE-A’s value proposition being high throughput taking maximum advantage of available frequency bands and multiple transmit and receive antennas, we will demonstrate how to get to performance results quickly using the Synopsys LTE-A library. This will feature throughput measurements with two different setups using standard defined MIMO channel models: first, an ideal receiver with perfect channel knowledge and second, a practical channel estimation module in the system.

What you will learn:
  • Overview of LTE-A standard
  • Overview of Synopsys LTE-A library and its use model
  • Performance simulation of LTE-A downlink system

Best Practices: Reduce Time to Results Using the Netbatch facility
The built-in netbatch facility allows sequentially scheduled System Studio simulations to be run in parallel to reduce time to results. It utilizes a network of workstations (built around Platform Computing Corporation’s Load Sharing Facility (LSF), Sun Grid Engine (SGE) software, or another software package of your choice) or enables the parallel execution of simulations on the local machine. The job management features of the netbatch facility also give you extended control over lengthy simulations running on the local machine. You can initiate a wait until the completion of a simulation, the final state of the simulation can be retrieved for postprocessing, and you can schedule a simulation to run within a predefined amount of time.

You can access the training on parallel simulation with netbatch (lecture slides + workbook) either via SolvNet (https://solvnet.synopsys.com/dow_retrieve/F-2011.12/ni/ccss.html) or via the Help menu in the tool itself. The training also comes with a lab example in the System Studio training library.
