Product Family: Software

Product Line: Data I/O

Product Part: abl2edif

Problem Title:
Foundation XABEL/ABL2EDIF: Logical Error 18823: Enable 'signal.OE' is only allowed when top_level specified.



Problem Description:


Urgency: Standard

General Description:

While synthesizing ABEL code with Foundation M1 Series
software, the following error may be encountered.

Logical Error 18823: Enable 'signal.OE' is only allowed when
top_level specified.

ABEL only allows tri-state buffer inference if the ABEL file being synthesized is a top-level ABEL file.


Solution 1:


Code the tri-state buffers out of the ABEL, and enter them in
another manner (VHDL, schematic, etc.).
