3.4.1.2.2. Synthesis Attributes in Verilog-2001
You must use Verilog-2001 attributes as a prefix to a declaration, module item, statement, or port connection, and as a suffix to an operator or a Verilog HDL function name in an expression.
Specifying Synthesis Attributes in Verilog-2001 and SystemVerilog
(* <attribute> [ = <value> ] *)
Applying Multiple Attributes
To apply multiple attributes to the same instance in Verilog-2001 or SystemVerilog, separate the attributes with commas.
(* <attribute1> [ = <value1>], <attribute2> [ = <value2> ] *)
For example, to set the maxfan attribute to 16 and set the preserve attribute on a register called my_reg, use the following syntax:
(* maxfan = 16, preserve *) reg my_reg;
