Hierarchical Design Using Synopsys and Xilinx FPGAs

Complex design issues can be addressed using block-based flows where working blocks can be preserved at the netlist level, and optionally at the placement or even the routing level. Unchanged blocks are automatically preserved during synthesis and implementation.

The main benefit of this flow is to reduce the number of implementation iterations … Read More → "Hierarchical Design Using Synopsys and Xilinx FPGAs"

Scaling Up to TeraFLOPs Performance with the Virtex-7 Family and High-Level Synthesis

This white paper provides an overview of fixed- and floating-point DSP coding techniques, ranging from RTL to the Xilinx portfolio of IP and tools. It also describes advances with High-Level Synthesis (HLS) tools, like AutoPilot, how FPGA designs can benefit from coding in a “natural language” like C or C++, and how easily FPGAs can be programmed by a large community of software programmers.

Authors: Oliver Garreau and Jack Lo, Xilinx

Parameterizable Content-Addressable Memory

This application note describes a parameterizable content-addressable memory (CAM), and is accompanied by a reference design that replaces the CAM core previously delivered through the CORE Generator™ software. The CAM reference design should be used for all new FPGA designs targeting Virtex®-6, Virtex-5, Virtex-4, Spartan®-6, Spartan-3, Spartan-3E, Spartan-3A, Spartan-3A DSP FPGAs, and newer architectures. All the features and interfaces included in the reference design are backward compatible with the LogiCORE™ IP CAM v6.1  … Read More → "Parameterizable Content-Addressable Memory"

3D ICs

It wasn’t very long ago that managing off-chip interconnect was a no-brainer. The interconnect path was very straightforward. It started at a pad on the chip, went out through a bond wire then connected to a metal lead, which connected to the PCB. The number of “interfaces” was small; a total of 4 counting the pad on the chip, the bond wire, the metal lead and the PCB, as illustrated in Figure 1.

Fair Trading

Until the coming of the railway, many European towns, in addition to their regular market, would have an annual fair. These were important events, with merchants travelling long distances to sell exotic goods. The privilege of holding a fair was jealously guarded, and the license or charter was given or withheld by a ruler. In my home town, Winchester, the Bishop had the license for the fair and charged the traders rent. To ensure that they got value for their money, the Bishop closed all the normal shops in the town for the duration of the fair.  In … Read More → "Fair Trading"
