AcreoAcreo Uses Visual System Simulator to Successfully Optimize System Performance of Complex UWB Transceiver. Visual System Simulator (VSS) provides deeper understanding of different system aspects and streamlines optimization of various parameters. The Design ChallengeThe need for higher capacities within Internet infrastructure is driving the demand for network architectures capable of supporting 100Gb/s Ethernet (IP) based traffic. One such bandwidth-efficient technology being explored is sub-carrier multiplexing (SCM), where quadrature modulated (QAM) signals on different carrier frequencies are combined and subsequently encoded onto an optical carrier. This transceiver approach capitalizes on the increasing speed of silicon technology (65nm complementary metal oxide semiconductor CMOS process on HR-SOI substrate) to perform more of the signal processing in the electrical domain before converting to light. The SolutionWhat design problem did AWR's software help you to solve? We needed to create a SCM transceiver link suitable for 100Gb/s transmission. The system-level development of a SCM transceiver link was modeled within AWR's Visual System Simulator. This RF system model enabled us to assess the influence of component performance in the electrical domain, particularly non-linearity and noise, with respect to the SCM link performance requirements. The design of critical component building blocks in the 65nm CMOS SOI process such as IQ modulators, power combiners, and low noise amplifiers (LNAs) for the SCM transceiver, were done at the circuit level. The performance of these components was then assessed in the VSS system simulation environment to investigate the capabilities of CMOS for next generation optical networking with the SCM architecture. "Using Visual System Simulator together with Matlab® to create the RF system model proved to be a straightforward task." said Lars Pettersson, research engineer at Acreo. "The flexibility, ease-of-use, and open platform of Visual System Simulator was a very positive feature. Visual System Simulator gave a good understanding of how group delay variations affected the whole system performance and we were able to optimize the system using this knowledge."

S5 WirelessS5 Wireless increases wireless design productivity using Visual System Simulator. The Design ChallengeI am designing radio architectures and need to visualize and simulate implementation details of the architectures using different modulations. I need to evaluate system performance with real-world impairments including DSP limitations and non-ideal circuit implementation. I must also quantify the performance impacts of channel interference, noise, jitter, etc. to optimize the design, so I need to be able to simulate these effects in order to optimize my design. The SolutionPrior to adopting AWR’s Visual System Simulator (VSS) software, I was building FPGAs and testing them in the lab, trying to integrate RF/analog/digital on hardware test benches, and simulating with disparate tools that were not integrated. With VSS, I have an excellent RF tool combination in an open design environment that enables me to quickly and accurately co-simulate circuit performance at the system level. VSS has helped me deliver higher quality products while at the same time significantly cutting my design time. Read More Visual System Simulator Success Stories >> |
"VSS has increased my productivity by providing more accurate results while at the same time cutting design cycle time. The software offers an intuitive design flow that has allowed me to quickly evaluate modulation schemes and radio/RF/DSP architectures, and has helped us optimize our system engineering design flow."

TriQuint Semiconductor, Inc.TriQuint Designs Power Amplifier 2X Faster and More Accurately Using Visual System Simulator. The challenge was to design an EDGE/GSM power amplifier for a cellular handset. It was essential to accurately characterize the power amplifier’s circuit performance at the system level and to accurately predict adjacent channel power ratio (ACPR) measurements using modulated signals as opposed to traditional two-tone analysis. AWR’s Microwave Office® and Visual System Simulator (VSS) software were used for the design. What design problem did AWR’s software help you to solve?I was able to accurately characterize power amplifier circuit performance at the system level and accurately predict ACPR measurements using modulated signals as opposed to traditional two-tone analysis. What were your reasons for choosing AWR software?
What were your reasons for choosing AWR software?The ACPR measurements simulated with VSS agreed with laboratory measurements, and the VSS simulation ran approximately two times faster than the alternative solution. What, in your estimation, are the most positive features of AWR’s software?The user environment, interactivity of the VSS system tool with the Microwave Office circuit tool, and the superior technical support.

"The seamless integration of the Microwave Office and VSS software gave me more meaningful results because I was able to simulate my power amplifier circuit design’s response to the EDGE/GSM modulated input signal with one design platform. I used Microwave Office and VSS from circuit concept all the way through to product completion. I was exceptionally happy with the technical quality of the ACPR and EVM simulation results.
