7.1i XST - How do I pass the STEPPING attribute through HDL in XST?

描述

How do I pass the STEPPING attribute that is available to access the enhanced multiplier speed?

解决方案

VHDL Example: 

 

entity multiply is  

port (<port_list>);  

 

attribute STEPPING : string;  

attribute STEPPING of multiply : entity is "1";  

end multiply;  

 

 

Verilog Example: 

 

module multiply (<port_list>); //synthesis attribute STEPPING of multiply is 1  

endmodule 

 

 

For more information about the STEPPING attribute, see (Xilinx Answer 14339).
