In addition to a selected or directly visible named entity with the same simple name as the entity that has been analyzed into either the same working library or a reference library there's something called a default binding indication, which requires that the port declarations match formals in the port map and the port map obeys semantic rules for association lists. If this were Stackoverflow someone would pop up and suggest you provide a Minimal, Complete, and Verifiable example <https://stackoverflow.com/help/mcve> instead of snippets then complain when you can't get a quality answer without sufficient information. > 13.05.2017, 14:38, "Paebbels" <paebb...@gmail.com>: >> Hello, >> >> have you analyzed adder before that component? >> Please provide the executed GHDL commands. >> >> Am 13.05.2017 1:34 nachm. schrieb "Тихомиров Валентин" <intel...@yandex.ru >> <mailto:intel...@yandex.ru>>: >> > adder_0: entity work.adder port map (i0 => i0, i1 => i1, ci => ci, >> s => s, co => co); >> >> > adder is not directly visible. >> >> Thanks but "work" does not improve anything.
