CoWare Inc. has extended is SPW (Signal Processing Worksystem) products with the SPW 2010.1, which includes enhanced LTE wireless reference library and a complete Xilinx implementation flow that includes direct source translation technology from C Data Flow (CDF) into RTL.

The LTE reference library implements reference system simulation models that allow validation and exploration of many different use cases. They span areas that are critical for network operators, handset manufacturers, transceiver and modem semiconductor companies as well as base station manufacturers.

The current release adds support for the physical random access channel, which can generate any preamble at any allowable cyclic shift, calculate the probabilities of detection and miss detection or false alarm in the receiver. It also supports modeling multiple users, which is critical for base station manufacturers.

Models for uplink and downlink control channels allow simulation of all of the encoding and decoding for broadcast, control format indicator, and hybrid ARQ indicator. Through the flexibility of the CoWare SPW CDF infrastructure, customers are already prepared for the exploration of LTE-Advanced, as well. Together with the legacy libraries for 2G and 3G, CoWare SPW also enables overall system integration.

SPW 2010.1 now offers direct source translation technology, which takes CDF models and translates them to RTL. Using the polymorphism in SPW, this technology allows the user to have floating-point, fixed-point and bit-true cycle-accurate blocks in C++ and synthesizable Verilog/VHDL from a single CDF model, thereby reducing development and verification time dramatically.

"The implementation of digital signal processing is greatly simplified when you use the right model of computation," said Professor Edward Lee, University of California, Berkeley. "Some of the modeling technologies from our Ptolemy project have been previously incorporated into the SPW simulation technology. From my vantage point, CoWare has the right modeling foundation to expand into software implementation, as well."

"In my recent book on ESL, ESL Models and their Application, I wrote about data flow modeling as an important model of computation in many modern systems," said Grant Martin, chief scientist at Tensilica. "I am glad to see that CoWare continues to evolve its technology to serve the needs of designers who are specifying and implementing digital signal processing."

CoWare SPW 2010.1 is available immediately.
