The package is a separate design unit and is analyzed before any entity declaration that needs to use the type it provides. We can use the type by preceding an entity declaration with a use clause, for example:
Some time ago I was told there were problems in the standard, where attributes were incorrectly allowed or disallowed within certain grammatical productions, against the intent of the design. This is a vague memory, so I don't know to what extent the claim is or was true, but it could pa...

"Scope" has got to be one of the most confusing words in all of programming language design. People seem to use it casually to mean whatever is convenient at the time; I most often see it confused with lifetime and declaration space. As in "the memory will be re...
In the initial discussion about inferring expression types, we assumed that the attributes name.type and num.type were already defined by some external mechanism. To fill in those values using an attribute grammar, the compiler writer would need to develop a set of rules for the portion of the...
There were a bunch of errors with the vhd file associated with the 7400 series component libraries I am using in the design. I added a bunch of backslashes to the vhd file but now have one error left, vhdl syntax error, near text DECLARE, expect "begin", or declaration statem...
