F1.5isp1: When ABEL synthesis engine is run in NT 4.0 SP3, tkwdog process freezes computer (opening project, syntax check, synthesize, add to project)


Keywords: XABEL, ABEL, syntax check, tkwdog.exe, abl2edif, wowexec.exe, ntvdm, hang, hummingbird

Urgency: Hot

General Description:

When doing a synthesis check or compiling an ABEL design (using NT 4.0
SP3) the system spawns a tkwdog process that locks the system by
dominating the systems CPU usage.

Even after cancel ling the syntax check the tkwdog process is actively
absorbing all cpu usage. The only resolution is to terminate the tkwdog
process from the task manager.
The problem with this is that the system then becomes unstable.


This problem is caused by a name collision between the tkdata.dll and
Hummingbird Exceed 6.1 or Hummingbird NFS Maestro v6.0 or later.

A patch has been made to fix this problem and can be found at:

The zip file contains the DLL file, tkdata.dll, and a readme.txt file
