T'VALUE(X) is a value of type T converted from the string X. Note that significant nesting depth can occur on hierarchal designs. They are not technically reserved words but save yourself a lot of grief and do not re-define them. Enumeration literals are in plain lower case. http://stackoverflow.com/questions/1826322/vhdl-problem-with-std-logic-vector

I would apreciate more help. Thank you! The old DOS 8.3 format in lower case works on almost all operating systems. The fact that code that was working just fine (and is clearlycorrect) has now broken says to me that the real problem is elsewhere,but how to find it?The source is a
But the error that you posted is that the compiler is complaining because the expression is not of type 'std.standard.integer'. Most of it is provided by using packages. Are you using that brand X simulator again?-- Mike Treseler rickman 2008-08-05 14:37:09 UTC PermalinkRaw Message Post by Mike TreselerPost by rickmanThe error is "(201, 28): Operator "=" is not defined navigate here Note that inout and out are not allowed for functions.
A process has some additional capability not available in a concurrent procedure. I fixed that. (Although i'm still not getting the output i need :( ). I am not use to the language and so, to this kind of error messages which are not very descriptive to me. The context clause of a primary unit applies to all of the primary units corresponding secondary units.

I have made some code for a wishbone model in VHDL and some procedures to write and read to it I think that there is no problem with the procedure but T'BASE is the base type of the type T T'LEFT is the leftmost value of type T. (Largest if downto) T'RIGHT is the rightmost value of type T. (Smallest if downto) The language is free form with the characters space, tab and new-line being "white space."
