Compilation error with Synplify attribute

Jul 15, 2005 2 Replies

I used the syn_preserve synplify attribute in my VHDL code as below.



attribute syn_preserve of sign1: signal is true;



Modelsim gives compilation error for this? Any help to rid of this would be appreciated.



Thanks, Muthu



You are probably missing the declaration of the attribute.

attribute syn_preserve : boolean;

Alternately, you could include the Synplicity library, which defines the attributes. But I typically do it the way Ken suggested.
