RE: [IBIS-Users] ibischk4

Hello, Chetana,
 
Here are some of the reasons behind these naming limits.
 
* Case sensitivity of file name: some operating systems (such as Windows) do
not recognize a case difference in a file name, while others (UNIX, Linux)
do.  To make file names behave consistently for all IBIS tools, file names
must all be lower case.
 
* File name length is consistent with file name limits in earlier operating
systems (8.3, for a total of 9 characters).  Some tools might still have
this coded into their operation.  One could check to see whether a BIRD has
been filed to have this increased.  The page with the IBIS specification
includes a list of BIRDs and instructions on how to file a new BIRD.
 
* Length limits on names (model names, etc.): The line length limit is 120.
Some tools might not read past the 120th character in a line.
 
* To preserve IP names, one can put them in comments in a line above the
component or model name.  One could also include a name matching list in the
[Notes] for further documentation.
 
Best regards,
Lynne

Subject: [IBIS-Users] ibischk4



Hello All,



While running ibischk4 on IBIS Models, 


I come accross some errors related to file name and model name. 


Ex: If file name / model name is too long, error is 


"File_name string is too long, truncating to 12 characters" 


"File_name contains an upper case character " 


"Model name string is too long, truncating to 20 characters"

Is there any way I can get rid of these errors without changing the IP name
and model name ?

What is the reason behind having this constraint on file / model names ?

Thanks

Best Regards
Chetana
