3.1i Modular Design - Ngdbuild will crash if there are multiple instantiations of the same module.


Keywords: ngdbuild, crash, multiple, instantiations

Urgency: Standard

General Description: Ngdbuild will crash during the assembly stage
when there are multiple instantiations of the same module.

This is a modular design limitation at this time. Ngdbuild should give an error message, not a segmentation fault.

Release 3.1i - edif2ngd D.17
Copyright (c) 1995-2000 Xilinx, Inc. All rights reserved.
Writing the design to "fir.ngo"...
Loading design module
ERROR:NgdBuild - Found 3 active blocks 'fir' in the design.
Segmentation Fault


A work around is to make a separate copy of the module with a
unique name for every module instantiation.

A fix will be added to the first 3.1i quarterly update to so that
ngdbuild exits with an error instead of crashing.
