Power delivery net (PDN) is vital for FPGA and structural ASIC devices packages to deliver power supply with high fidelity from system board to IC chips, which requires low impedance maintained over the entire frequency range of device under operation. Many efforts have been spent to lower PDN impedance, including increased use of on-die, on-package and on-PCB decoupling capacitances. In this study...
This paper discusses recent progress made in power distribution network (PDN) characterization, modeling and hardware-to-model correlation in Altera. A complete methodology and process are introduced for accurate PDN measurement and associated equivalent RLC parameter extraction. The proposed method is validated through modeling and measurement correlation and believed to be beneficial to system users...
Simultaneous switching noise (SSN) and its behavior have become increasingly important in high-performance FPGA system design featuring hundreds of I/Os transmitting in parallel at low supply voltage standard. In this paper, we present an in-depth study on SSN by analyzing its behavior in three different domains: time, frequency, and noise spectrum. Cross correlation in these three domains reveals...
