Hi Eric,
I take it you are trying to create a pin list for an ibis file. You can find information on this in the IBIS Information Specification Ver 3.2 http://www.vhdl.org/pub/ibis/ver3.2/ver3_2.pdf
The number of characters allowed per column in the pinlist section of the ibis model are as followed:
[Pin]: Max 5 characters allowed
signal_name: Max 20 characters allowed
model_name: Max 20 characters allowed
R_pin: Max 9 characters allowed
L_pin: Max 9 characters allowed
C_pin: Max 9 characters allowed
I would suggest avoiding using symbols other than integers (1,2,3,...) and letters (A,B,C,...) in in the [Pin] column.
See the document in the link specified above, it show a sample pinlist section.
Hope this helps.
Thanks,
Abdulrahman Rafiq

When assigning for pin name, I am not sure there is any limits except column length. of character. For example, if naming by "#", "", "(xxx)", "!", or even "%"? In case they can pass by "ibischk3", does it also mean they are acceptable by any commercial simulation tool as long as it can accept IBIS format?
Best Regard,
