Discussion:
a. New IBISCHK7.2.1 draft bug254 “AMI Reserved Parameter Repeater_Type 
   erroneously reported as missing”
   The origin of this issue is from a TI model. The IBIS file and AMI file did 
   not have the repeater model information. Randy added the relevant 
   information in the AMI and IBS files. Arpad then tested the model and found 
   the bug. The DLL issued an error if some of the required keywords that 
   should be Usage Info were not Usage In. Changing the Usage to In allowed the 
   DLL to run the simulation, but then the parser issues the error that the 
   Repeater_Type is not found. This is a corner case. The parser catches the 
   actual error about the Usage In, but then issues a secondary error about the 
   Repeater_Type missing.
   The severity is set to moderate because the error can be misleading.
   The priority is set to low because it is unlikely to occur and is easy to 
   fix in the AMI file.

Weston moved to adjourn. Randy seconded. Without objection, the meeting ended.
