Powering Altera ArriaВ 10 FPGA andВ Arria 10 SoC: Tested
and Verified Power Management Solutions
Design Note 549
Afshin Odabaee
Introduction
FPGA development kits allow system developers to
evaluate an FPGA without having to design a complete
system. Figures 1 and 2 show AlteraвЂ™s new 20nm
Arria 10 FPGAs and Arria 10В SoCs (System-on-Chip)
development boards. These boards are tested and
verified by Altera, exemplifying best design practices
in layout, signal integrity and power management.
Power Management for Core, System and I/O
The power management solution for high end FPGAs,
including the Arria 10, should be carefully selected.
A well thought-out power management design can
reduce PCB size, weight and complexity, as well as
lower power consumption and cooling costs. And it
is essential to achieve optimal system performance.
ForВ example, the 0.95V at 105A supplied by the 12V
DC/DC regulator powering the core of the Arria 10 GX
FPGA in Figure 1 has several features that complement
the power saving schemes of the SoC: Figure 1. Arria 10 GX FPGA Development Kit …

Avoid Debugging Cycles in Power Management for FPGA,
GPU and ASIC Systems
Afshin Odabaee When it comes to designing FPGA, GPU or ASIC controlled systems, the number of
design challenges related to power management and analog systems pale in comparison
to those related to digital design. Nevertheless, it is risky to assume that power system
design can be left to вЂњlater,вЂќ or taken in line with digital design. Even seemingly innocuous
problems in power supply design can significantly delay the release of a system, as any
added time to the power system debugging cycle can halt all work on the digital side.
A good way to put DC/DC regulation
issues to rest is to use a verified development kit offered by the FPGA, GPU or
ASIC vendor. Often, the design itself or
a similar design is available as a board/
kit by the suppliers of power products
and FPGA, GPU and ASIC manufacturers. Using a tested and verified kit unburdens
system designers of most power system
and analog issues, allowing them instead
to focus their energies on configuring the
complex digital systems. The optimum
power system layout is taken care of
before significant design is undertaken. THOUGHTFUL POWER MANAGEMENT
IS CHALLENGING AT THE START Every design task is initially daunting,
and power management design is no
exception. This is the case when power is …
