چکیده

We present a methodology to detect and measure the signal overshoots occurring on the interconnects of high-speed system-on-chips. Overshoots are known to inject hot-carriers into the gate oxide which cause permanent degradation of MOSFET transistors’ performance over time. We propose a built-in chip mechanism to detect overshoots, collect the occurrence information and scan them out efficiently and inexpensively for built-in self-test, reliability analysis and diagnosis.

Detecting signal-overshoots for reliability analysis in high-speed system-on-chips

The rising level of complexity and speed of SoC makes it increasingly vital to test adequately the system for signal integrity. Voltage overshoot is one of the integrity factors that has not been sufficiently addressed for the purpose of testing and reliability. Overshoots are known to inject hot-carriers into the gate oxide and cause permanent degradation of MOSFET transistors’ performance. Th...

Thermal management of ARM SoCs using Linux CPUFreq as cooling device

While the performance of modern ARM System on Chips (SoCs) increases significantly than the previous generation, the power dissipation and on-chip temperature becomes dramatically high. The existing thermal management solutions are mostly built on Advanced Configuration and Power Interface (ACPI) and Dynamic Thermal Management (DTM) model for traditional desktop and server machines. They do not...

Embedded Memory Test Strategies and Repair

The demand of self-testing proportionally increases with memory size in System on Chip (SoC). SoC architecture normally occupies the majority of its area by memories. Due to increase in density of embedded memories, there is a need of self-testing mechanism in SoC design. Therefore, this research study focuses on this problem and introduces a smooth solution for self-testing.  In the proposed m...

Many of today’s chips demand more embedded memory than ever before

Many of today’s chips demand more embedded memory than ever before. SoCs and FPGAs are also moving from logic-dominant to memory-dominant chips. The addition of memory, while it creates a more powerful chip, increases die size and results in poor yield. As the percentage of embedded memory continues to increase, so does the chip’s complexity, density, speed and of course, the probability of fai...
