Grouping TIG NETS ISE 14.7 Spartan 6 XC6SLX150TFGG900

Jump to solution

Hello. I'm working with Spartan 6 XC6SLX150TFGG900 and ISE 14.7. I would to group some nets and assign them the TIG constrain so that are ignored the time requirments from these nets to each other nets of the design. I thought to do this appending to each of these nets the suffix  _TIG_ . For example:

 

"net_name1_TIG_"

"net_name2_TIG_"

"net_name3_TIG_"

.........

"net_name99_TIG_"

 

And then I thought to group the nets and apply constrains in the ucf in this way:

 

TIMEGRP "TN_TIG" = FFS(  " * / * _TIG_ / * " ) ;

 

TIMESPEC TS_TIG = FROM  " TN_TIG "  TIG;

 

Is this a good idea? There could be be problems resolving constains having underscores in the name of the nets? Is there a simpler and safer way to do what I want? Thank you.
