[Synth 8-1031] equal is not declared ["..........................decode_frame.vhd":212]

 

В Vivado  и rx_pack.vhd   decode_frame.vhd - в library work поместил.

В compile_order правильно: rx_pack.vhd, затем   decode_frame.vhd

Что делаю не так ?

Все так.

rx_pack попал в - unreferenced !

Например, Константы не видятся:

Вопрос снят.

Переименовал library work в eth, и файлы поместил в эту lib. - Заработало.

Почему vivado игнорирует library work- загадка природы.
