SI Fundamentals

Feature size reduction and the need for reduced power consumption has driven core voltages down from the old standard of 5V to the 1.0V range. This change in voltage and signal frequency content requires us to use new design practices that take into account electrical effects that could previously be ignored.

Methodologies for Efficient FPGA Integration into PCBs. A system-level summary of PCB design flow, with emphasis on signal and power integrity aspects. It is relevant to all Xilinx devices up to the Virtex™-II Pro series.
Signal integrity and high-speed PCB design: Issues, Tools and Methodologies. This series of articles explores tools and methods you can use to combat signal and power integrity distortions throughout product development.
Ten reasons why performing signal integrity analysis makes a lot of sense.

Calculators and Estimators

When designing a board with elaborate ICs such as FPGAs, it is important to calculate the FPGA demand on the PCB and vice-versa. We provide information on signal integrity, static and dynamic power, and SSO:
