4.1i XST - "ERROR: Xst:612 - Data Corruption (Ngo out) cannot find DM cell for <primitive>" (Incremental synthesis)


Keywords: incremental, synthesis, instantiate, primitive, XST, VHDL, Verilog

Urgency: Standard

General Description:
When I perform incremental synthesis on a project with instantiated primitives, the following messages are reported:

"Incremental synthesis: <top_level>.edn file not found.
Incremental synthesis: <primitive>.edn file not found.
ERROR: Xst:612 - Data Corruption (Ngo out) cannot find DM cell for <primitive>."


If you are using the 4.1i software, you can safely ignore the messages, as the design will implement without errors.

Many of these incremental synthesis issues were fixed in the 4.2i software release.

A number of the remaining incremental synthesis issues are resolved in Service Pack 1 for 4.2i, which is available at:
