This paper presents a crosstalk model base on even-odd mode analysis. It demonstrates that crosstalk analysis needs to look at the aspect of the timing delay between even and odd mode and the multiple reflections that occurred in a system. This concept is validated further by measurement result.
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...
A design of the proper frequency behavior of a power distribution network (PDN) of input/output (I/O) circuitry of an FPGA enhances performance and is able to withstand synchronous switching noise (SSN) for applications in specific frequency bandwidths. A methodology of PDN evaluation and modeling is presented in this paper, with different types of packages having on-package decoupling capacitance...
This paper discusses the fundamental constraints of current packaging technology and how they affect the performance of multichannel 10-Gbps FPGAs. FPGA packages act as interconnects between dies and system boards. While IC chips take advantage of Moore's law for dimension and cost reduction, system boards traditionally have not. From design optimization practice, we conclude that the inherent dimension...
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...
