[IBIS-Users] RE: [IBIS] Why IO buffer name is limited to a max of 20 characters

Venu,
 
This is rooted in the earlier versions of the spec when
the line length was limited to 80 characters, and therefore
we had limited space for each field on the lines of the
[Pin] section.  Now that the line length limit is 120
characters (if I am not mistaken), we could allow for 
longer model names, but someone would need to write a
BIRD for it.  Do you want to volunteer?

Subject: [IBIS] Why IO buffer name is limited to a max of 20 characters



Hi All,

 

Is there any specific reason exist to restrict the IO buffer name to a maximum of 20 chars in our IBIS standard? Can't we change this rule to allow more than 20 chars as buffer name? 

 

Recently, I experienced some IO buffers which have more than 20 chars in their names. So, I have to truncate the IBIS model name to support this rule. If choice is given I do not want to truncate the IBIS model name. 

 

Thanks in advance,

 

Best Regards,

Venu
