AR# 9835

3.1i XST - Incremental Synthesis does not appear to work (only one EDIF file in the directory)

Description

Keywords: incremental, synthesis, edif, vhdl, verilog, hdl, modular, design

Urgency: Standard

General Description:
The incremental synthesis option for XST does not appear to work as there is only
one EDIF file that goes through implementation.

Solution

XST will not run the incremental synthesis option if the top level edif file from a non-
incremental synthesis run already exists in the directory. The workaround is to
remove the single top level EDIF file and then re-run synthesis.
