Скорее всего, в этом же банке у Вас есть ноги, задействованные под стандарт, который требует наличия Vref.
Вроде ничего такого не делал. Все, кроме core, на 3.3 вольта. Ругается на выходы P35, P97, P53 и P80. Как объяснить что Vef - "Это тоько IO?
Мапер говорит :
Код
Pack:1107 - Pack was unable to combine the symbols listed below into a single IOB component because the site type selected is not compatible.
Further explanation:
The component type is determined by the types of logic and the properties and configuration of the logic it contains. In this case an IO component of type IOB was chosen because the IO contains symbols and/or properties consistent with output or bi-directional usage and contains no other symbols or properties that require a more specific IO component type. Please double check that the types of logic elements and all of their relevant properties and configuration options are compatible with the physical site type of the constraint.
Summary:
Symbols involved:
BUF symbol "INT0_OBUF" (Output Signal = INT0)
PAD symbol "INT0" (Pad Signal = INT0)
Component type involved: IOB
Site Location involved: P80
Site Type involved: DIFFSI_NDT
