During elaboration, if + a component is not bound to an entity using VHDL LRM rules, try to + find in any known library an entity whose name is the same as the + component name. + + This rule is known as the synthesizer rule. + + There are two key points: normal VHDL LRM rules are tried first and + entities are searched only in known libraries. A known library is a + library which has been named in your design. + + This option is only useful during elaboration. + .. option:: --format=<FORMAT> Define the output format of some options, such as :option:`--pp-html` or :option:`--xref-html`. |
