Hi again! 

 

Does anyone know how to turn this off in Version 10? It's adding macrocells to my design that I just can't afford.  

 

This system message: 

 

Info: Promoted clock signal driven by pin "clk" to global clock signal 

 

 

Thanks!

Actually, that website doesn't help at all. The option it specifies isn't there... :(

Hi, 

 

open the Assignment Editor. Double click into the tab "Assignment Name" , choose "Global signal". Go to the value tab and choose "off". In the "to" tab you have to specify your signal. Using "*" should switch the global feature off. That should solve your  

problem. 

 

Kind regards
