General Description: When I attempt to synthesize a multiple module ABEL design in Foundation 4.2i, the following error is reported:
"Error: could not find the file <module_name>.abl"
解决方案
ABEL designs that consist of multiple modules must be broken up into separate files -- each module must reside in its own file.
This requirement is limited to Foundation Classic (i.e., Foundation with the Aldec design entry tools); the requirement does not exist for WebPACK or ISE Project Navigator.
