Synopsys introduces TDD mode in its LTE
model library for physical layer system simulation
Synopsys has made available the Time Division Duplex (TDD)
mode in its Long-term Evolution (LTE) Model Library for
physical layer system simulation for the VLSI designers
of LTE semiconductor ICs to support 3rd Generation Partnership
Project (3GPP) LTE standard.
Synopsys' LTE library includes models of the transmitter
and the physical channel as defined in the 3GPP standard
and 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.
This mode in LTE Model Library enables development of multi-mode
modems for the entire LTE standard.
"The use of behavioral models of Xilinx's baseband
IP together with the Synopsys LTE Model Library allows customers
to assess the performance advantages of our IP within the
context of a standards-compliant system," said Mark
Quartermain, baseband marketing manager at Xilinx. "Synopsys'
ability to deliver an end-to-end LTE physical layer model
along with high-performance simulators enables system architects
to accelerate their algorithm design by relying on standard-compliant
reference models for the entire physical layer simulation
chain."
Synopsys says the LTE Model Library offers 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 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.
"The complexity of the LTE standard requires simulating
more than 100 billion test vectors to check for compliance,
creating quite a verification challenge," said Johannes
Stahl, director of marketing for system-level design at
Synopsys. "Our LTE models are highly optimized for
simulation performance. Together with our advanced algorithm
design tools, the new LTE Model Library helps base station
and handset modem designers ensure their functional design
meets the LTE standard in the shortest possible time."
Availability:
The TDD-enhanced LTE Model Library is available now.
Support for System Studio will follow in Q3 2010.
