Synopsys has added Time Division Duplex (TDD) mode to their Long-term Evolution (LTE) Model Library for physical layer system simulation. TDD mode helps developers of semiconductors for LTE network equipment and devices to quickly and reliably extend designs to support the third Generation Partnership Project (3GPP) LTE standard. The TDD-enhanced LTE Model Library is available now for use in SPW. Support for System Studio will be available this year. Existing licensees of the LTE Model Library will receive the TDD enhancement as a regular maintenance update.
The Synopsys LTE Model Library features ready-to-use, standard-compliant test benches and simulation scripts that cover the test scenarios as defined in the LTE standard document. Models and scripts adhere to release 8.9 of the 3GPP LTE standard and will be upgraded as the standard evolves. In addition, the reference models in the LTE Model Library have been optimized to take advantage of the stream-driven data flow technology in Synopsys’ SPW and System Studio tools, and are designed to provide a comprehensive and efficient development environment for advanced digital signal processing design.
The 3GPP LTE standard is the latest standard in mobile network technology. The primary advantages of LTE are high throughput, low latency, a simple architecture resulting in low operating costs, and support for both TDD and Frequency Division Duplex (FDD). Synopsys’ LTE library includes models of the transmitter and the physical channel as defined in the 3GPP standard as well as functional models of ideal receivers that can serve as references, providing an end-to-end simulation chain for both uplink and downlink transmission and reception. By leveraging both FDD and TDD mode models from the LTE Model Library, designers can focus on the development of highly-optimized, multi-mode modems for the entire LTE standard.
