PARSER VERSION NUMBER: 5.1.3

PLATFORM (SPARC, HP700, PC, etc.): PC

OS AND VERSION: Windows 7

REPORTED BY: Bob Ross, Teraspeed Consulting Group, Arpad Muranyi, Mentor Graphics

DATE: May 4, 2013

DESCRIPTION OF BUG:

Interal AMI_Version number fails to reset to Version 5.0 for .ami checking


The test case consists of

  bug146.ibs   (check with ibischk5 -numbered bug146.ibs)
  bug146a.ami  (an AMI_Version "5.1" file)
  bug146b.ami  (an AMI_version "5.0" file with Init_Returns_Output)
  bug146.dll   (a meaningless dummy file)

The bug146.ibs file checks Rx models which alternately call bug146b.ami,
then bug146a.ami.  The second call to bug146b.ami shows the failure, even
though it is a Version "5.0" file with a legal Use_Init_Output branch.

The error message for the set of files below is shown with comments:

IBISCHK5 V5.1.3
