#51 Syntax for signal declaration using 'subtype with an initial value

signal a : b'subtype := initial_val;

signal a : b'subtype:= initial_val;

Hi, I get a syntax error telling me there is an unexpected space in the following: signal a : b'subtype := initial_val; The error is due to the space after 'subtype before := The below line does not experience the error: signal a : b'subtype:= initial_val; Thanks
