illegal characters of net name

skillnewbie

hi,

I wanted to create a net with the name contains characters "!"

when i input the net name like "VSS!" , it prompts Error Not legal characters.

anyone can help on this?

thanks in advance 

  • From the 16.2 doc set:

    Net name is limited to 30 printed characters, all except ! and '

    The default maximum number of characters is 30. You can set the initial length for new designs to a maximum length of 255 by using the allegro_long_name_size environment variable (choose Setup - User Preferences (enved command)). You can change the size in existing designs by choosing Setup - Design Parameters (prmed command) and specifying a new maximum for the Long Name Size parameter in the Design tab.

     

    Regards,

         

  • hi BillAcito,

     Thanks for the info~ yes i have found the illustration in the algrostart PDF doc,

    it seems that this is a limit of Allegro.

    is there a reason for this? not only the net name, but also usual text string.
