In FPGA design timing is everything, says Synopsys
When your FPGA design fails to meet timing performance objectives, the cause may not be obvious. The solution lies not only in the FPGA implementation tools’ talent in optimising the design to meet timing, but also in the designer’s ability to specify goals upfront and diagnose and isolate timing problems downstream. Designers now have access to certain tips and tricks that will help you set up clocks; correctly set timing constraints using tools like Synopsys Synplify Premier; and then tune parameters to meet the performance goals of your Xilinx FPGA design. - See more at: http://www.electronicsweekly.com/news/design/eda-and-ip/fpga-design-timing-everything-says-synopsys-2014-12/#sthash.Kgd9GbBl.dpuf

How to Bring an SMC-Generated Peripheral w/AXI4-Lite Interface into the Xilinx Environment
Synphony Model Compiler (SMC) is a model-based tool from Synopsys that synthesizes designs created in Simulink® and MATLAB® to generate optimized RTL for ASIC and FPGA targets. SMC includes a comprehensive high-level model library for creating math, signal-processing and communications designs in the Simulink environment. Using the included SMC Host Interface Block makes it simple to integrate a design you’ve created with the Synphony Model Compiler into a Xilinx embedded platform.

The fixed and the finite: QoR in FPGAs
There is an intriguingly amorphous term in FPGA design circles lately: Quality of Results, or QoR. Fitting a design in an FPGA is just the start - is a design optimal in real estate, throughput, power consumption, and IP reuse? Paradoxically, as FPGAs get bigger and take on bigger signal processing problems, QoR has become a larger concern.

Gigahertz FFT Rates on a 500MHz Budget
Today’s systems often present a massive amount of very fast data at the front end that needs to be sampled and decimated quickly, typical of a system with a lot of data channels in play like satellite radio or cable head-end systems. Sample rates run into the gigahertz range, putting them outside the range of FPGA clock speeds if the constraint is one sample per clock. In this article, learn how Synopsys’ parallel FFT IP implementation allows data to be sampled and processed faster.

Using Parallel FFT for Multigigahertz FPGA Signal Processing
Very high-speed fast Fourier transform (FFT) cores are an essential requirement for any real-time spectral-monitoring system. As the demand for monitoring bandwidth grows in pace with the proliferation of wireless devices in different parts of the spectrum, these systems must convert time domain to spectrum ever more rapidly, necessitating faster FFT operations. This article examines the design of a parallel FFT (PFFT) with runtime-configurable transform length, taking note of the throughput and utilization numbers that are achievable when using parallel FFT.

Automating the FPGA Design Debug Process
As FPGAs grow more capable, they will increasingly replace ASIC devices for certain applications where bleeding-edge performance or extremely large volumes are not required. And as the prevalence of FPGAs as integral components of products continue to increase, debugging of these large devices will only grow more arduous. These trends will render already antiquated gate-level debugging techniques totally obsolete. Only with more advanced debugging tools will we be able to meet next-generation time-to-market demands. This article, by Jeff Garrison, Director of Product Marketing FPGA Synthesis tools, discusses the challenges of debugging large FPGA devices and provides insight into the tools and methodologies that alleviate some of these challenges.
