(Note: The timsim8.log file gives no indication of a segmentation fault.)
The segmentation fault is caused by improper library calls in Mentor's main design-management shell. This program is used by Mentor's file-management commands to determine file types, hard path names, etc. PLD_DVE_BA, and thus Timsim8, uses a Mentor file-management command called delete_object, which in turn calls ddms_sh, the central design-management shell.
The improper library calls exist because ddms_sh was written for Solaris 2.3, and not Solaris 2.4 or 2.5.
The ddms_sh program may be updated to run under Solaris 2.4 and 2.5 with Patch 251, available on Mentor Graphics' FTP site at supportnet.mentorg.com (22.214.171.124). The patch comes in three parts, a read-me file, installation instructions, and the actual DDMS program:
