Enumeration Type Literals not recognized

Posted Mon, 2009-11-09 10:15 by Darkadams
For Example Given the declaration in MyPackage.vhd type t_Aligner_State is (IDLE, PTRN_SEARCH, SLIP_BUSY, PTRN_OK1, PTRN_OK2, LOCKED); the following code ... use work.MyPackage.t_Aligner_State; ... architecture SYN of DUMMY is ... signal Aligner_State : t_Aligner_State; ... begin ... Aligner_State <= IDLE; ... end architecture SYN; " produces the following error "Declaration of IDLE could not be found" There is no workaround that I know of.
‹ Missing some features Use clause inside architecture block sometimes gives an (incorrect) error ›

Hi Dirk,

You have spotted a bug. When you import an enum datatype, we do not make the enum literals visible. I've logged this as ticket:646
For now, as a workaround, you can import the entire package: use work.packageName.all; like this:

package p1 is
   type t_Aligner_State is (IDLE, PTRN_SEARCH, SLIP_BUSY, PTRN_OK1, PTRN_OK2, LOCKED);
end package p1;
 
entity dummy is
end entity dummy;
 
use work.p1.all; -- use ALL
architecture SYN of DUMMY is
   signal Aligner_State : t_Aligner_State;
begin
   Aligner_State <= IDLE; -- works fine now
end architecture SYN;

This issue is fixed in the upcoming release.
