Although measurement methods for Electromagnetic (EM) immunity and Total Ionizing Dose (TID) radiation are highly standardized, no effort has been made to evaluate the behavior of embedded systems under the combined effects. Considering realistic environment conditions only the measurement of these effects can guarantee reliable embedded systems for critical applications. A configurable platform to...
Integrated circuits (ICs) are becoming increasingly vulnerable to malicious alterations, referred to as hardware Trojans. Detection of these inclusions is of utmost importance, as they may potentially be inserted into ICs bound for military, financial, or other critical applications. A novel on-chip structure including a ring oscillator network (RON), distributed across the entire chip, is proposed...
The performance and robustness to PVT variations has been measured of an improved Self Synchronous FPGA (SSFPGA) designed in 65 nm CMOS which achieves 2.97 GHz throughput at 1.2V. The proposed SSFPGA employs a 38×38 array of 4-input, 3-stage Self Synchronous Configurable Logic Blocks, with the introduction of a new dual tree-divider 4 input LUT to achieve a 4.5× throughput improvement...
FPGAs (Field Programmable Gate Array) are now widely used for prototyping systems as well as mid-volume products. These FPGAs are fabricated by the leading edge CMOS process technology. These may excite false logic transition due to simultaneous switching CMOS output buffers. In this paper, simultaneous switching noise of FPGA was investigated by both measurement and simulation. First, a precise circuit...
Electronic devices are increasingly susceptible to simultaneous switching noise (SSN) as devices shrink in size and operate at lower voltage to achieve higher speed. This is a major concern in high-speed system designs as SSN causes voltage and timing variations which affect signal integrity. Consequently, it is imperative that electronic system designers pay strict attention to signal integrity whether...
The low level signals faces many problems during their processing and digitization. The main affecting factor is the added noise during its propagation in mixed signal environment which makes very difficult to extract exact information from the signal. Additionally hardware requirement increases when we want to process these kinds of signals. In this paper, we proposed a customized hardware for this...
Complex electrical circuits for safety critical airborne hardware are subjected to a number of verification and validation techniques to assure the correctness of the design. These techniques can range from formal methods to failure tree analysis. Simultaneous Switching Noise (SSN) occurs when multiple circuit outputs change simultaneously. SSN can cause the circuit to operate incorrectly under rare...
This paper describes several methodologies based on a pulsed laser beam to reveal the architecture of a high integrated SDRAM, and the different classes of Single Event Effects that can occur due to cosmic radiations. At cell level, laser is used to reveal an important technological parameter: the lithography process. At memory array level, laser is a powerful tool to retrieve cell physical arrangements,...
The imaging laser radar is fine measure equipment for TAN with the ability to get the high precision 3D terrain. A 3D terrain matching processor was needed to be designed for the specifical application. In this paper, base on the specialty of the imaging laser radar, the3D terrain matching processor was designed, with scheme of DSP+FPGA calculating engine, multi-level memory system, flexible parallel...
In deep submicron era, to prevent larger amount of SRAM from more frequently encountered overheating problems and react accordingly for each possible hotspots, multiple ideal run-time temperature sensors must be closely located and response rapidly to secure system reliability while maintaining core frequency. This paper presented a method to extract run-time temperature information from multiple...
