Virtex-5 Configuration - What power rail should the mode pins be tied to?


Keywords: Vcc, aux, config, voltage, pull-up

What power rail should the mode pins on the Virtex-5 be tied to?


The mode pins need to be tied to VccConfig as they follow Vcco_0.

The Virtex-5 FPGA Configuration User Guide, v3.2 (UG191) states that the mode pins should be powered by Vccaux, and this will be changed in the next revision of the user guide.
