Document Table of Contents Trace Length Guideline

The maximum trace length apply to both single- and multi-device AS configuration setups as listed in the following table. The trace length is the length from the Arria® 10 device to the EPCQ-L device.

Note: To evaluate the data setup (tSU) and data hold time (tDH) slack on your board in order to ensure that you are meeting the tSU and tDH requirements, Intel® recommends that you follow the guideline in the Evaluating Data Setup and Hold Timing Slack section of the AN822: Intel FPGA Configuration Device Migration Guideline.
