Hello,
I encountered a error when I use synplify preimier to synthesis a VHDL design.
the log is
Code:
@E: CD505 :"/filepath/file1.vhd:497:30:497:36|type:Expecting enumeration literal
1 error parsing file /filepath/file1.vhd

and the code in this file1.vhd is:
Code:
497    type  start is (INIT, DEFAULT, ABORT, NOACT);
498   signal start_state : start;

anyone who can help on this? thanks.
 

Not sure, but "default" is a reserved VHDL keyword.
 

Thanks for you reply. But, the Modelsim compilation is OK. I am confused... Dose any features that Synplify not support?
