This technique is based on the reconfigurability feature of FPGAs. Using this technique, the delay of a defective path is increased several times more than the delay of the fault-free path, resulting in a higher resolution in detectability of resistive open defects in FPGAs, even at lower tester speed. Various detailed SPICE simulations are performed to validate this method. Also, a test configuration generation scheme is presented for the entire FPGA.","PeriodicalId":355740,"journal":{"name":"2002 IEEE International Conference on Field-Programmable Technology, 2002.

However direct translation of conventional firewall rules in a router-based rule set often leads to inefficient hardware implementation. Moreover, such lowlevel description of firewall rules tends to be difficult to manage and to extend. We describe a framework, based on the high-level policy specification language Ponder for capturing firewall rules as authorization policies with user-definable constraints. Our framework supports optimisations to achieve efficient utilisation of hardware resources. A pipelined firewall implementation developed using this approach running at 10 MHz is capable of processing 2.5 million packets per second, which provides similar performance to a version without optimisation and is about 50 times faster than a software implementation running on a 700 MHz PIII processor.","PeriodicalId":355740,"journal":{"name":"2002 IEEE International Conference on Field-Programmable Technology, 2002.

As VLSI design becomes larger and takes up much longer time, verification and debugging of logic design become the dominating part of total design period. FPGA is relatively useful in such case due to its rapid implementation. However, circuit performances are very sensitive to layout designs. Therefore minimal change of circuit structures is important. In this paper, we give a debug methodology targeting arithmetic circuits which modifies circuits locally and speeds up the total time for redesign as a result. To complete debugging, we analyze circuits, extract the erroneous parts, and replace by correct circuits.","PeriodicalId":355740,"journal":{"name":"2002 IEEE International Conference on Field-Programmable Technology, 2002.

This is mainly due to the sequential characteristic of such an implementation. In this paper, we investigate several hardware implementations of the SAD operation and map the most promising one in FPGA. Our investigation shows that an adder tree based approach yields the best results in terms of speed and area requirements and has been implemented as such by writing high-level VHDL code. The design was functionally verified by utilizing the MAX+plus II 10.1 Baseline software package from Altera Corp. and then synthesized by utilizing the LeonardoSpectrum software package from Exemplar Logic Inc. Preliminary results show that the design can be clocked at 380 MHz. This result translates into a faster than real-time full search in motion estimation for the main profile/main level of the MPEG-2 standard.","PeriodicalId":355740,"journal":{"name":"2002 IEEE International Conference on Field-Programmable Technology, 2002.

These were never possible using CMOS as the basic device. People were able to achieve frequencies in the range of 70-250 MHz using CMOS. The availability of Silicon Germanium (SiGe) Heterojunction Bipolar Transistor (HBT) devices has opened the door for Gigahertz FPGAs. An FPGA with a speed of over 5 GHz was reported by B.S. Goda (2000) using SiGe 5HP technology. However in order to scale up FPGAs significantly, a serious power management scheme must be in place. Apart from this, architectural changes can be made to improve the speed and reduce the power. This paper elaborates on the architecture of the new SiGe FPGA and its advantages over the previous generation SiGe FPGAs. The entire Configuration Logic Block (CLB) has been implemented using seven Current Mode Logic (CML) trees. Apart from these, a novel power management scheme is implemented which allows the FPGA to operate at multiple modes: fast, non-critical, slow and off. The new FPGA can run in the fast mode when speed is critical or in the slow mode when power is the limiting issue. The CLB can run up to 5.96 GHz.","PeriodicalId":355740,"journal":{"name":"2002 IEEE International Conference on Field-Programmable Technology, 2002. (FPT).
