This checklist provides a summary of the guidelines described in this document. Use
the checklist to verify that you have followed the guidelines for each stage of your
design.
Estimate power consumption and heat dissipation with the Early Power Estimator
spreadsheet to plan the cooling solution and power supplies.
Reduce I/O power consumption with lower I/O capacitance, lower voltage I/O standards,
and resistively terminated I/O standards for high frequency signals.
Select suitable I/O standard (single-ended, voltage-referenced, or differential) for your
design.
Place I/O pins that share the same V
Select the configuration scheme based on the Cyclone III device package, the resources
available for the configuration, and the configuration time required by your system.
For AS, AP, and PS configuration schemes, you can select either fast or standard POR time.
For AS configuration scheme, make sure the selected EPCS device supports the
configuration bitstream file size for the selected Cyclone III device.
For AS configuration scheme, use SFL to reduce the effort to have separate programming
interface for your Cyclone III and EPCS device.
When using MAX II PFL for PS or FPP configuration scheme, or when using FPGA-based
PFL for AP configuration scheme, ensure that you select the appropriate flash device
according to the list of supported flash devices.
Use the compression feature to reduce the configuration file size for AS and PS
configuration schemes.
Use the Cyclone III PLL for frequency synthesis and clock management.
Ensure that the PLL input, output, and VCO frequency are within the specification in the
datasheet.
Cascade the PLLs to obtain the frequency you need, if the m, n, c counter or VCO frequency
does not allow you to obtain the desired frequency when one PLL is used.
Use the clock switchover feature of the PLL, if you need a backup input clock or to change
the input clock source in user mode.
Select the PLL compensation mode that best fits your design requirement.
Use the PLL reconfiguration feature, if you need to change the PLL settings on the fly in user
mode without reconfiguring the entire Cyclone III device.
Select a device based on the logic/memory/multiplier density, device features such as PLLs,
I/O pin count, package offering, and additional resources for debugging future development.
Consider vertical device migration requirements. Consider availability of speed grades.
Ensure sufficient timing margin if you plan to use a lower speed grade device in the future.
