7.1i XST - How do I use incremental design for a single file with multiple modules?

Description

Keywords: synthesis, VHDL, Verilog, flow, coded

Urgency: Standard

General Description:
The Incremental Design flow tracks when and which modules have changed, and only re-synthesizes those modules. However, the process assumes that each module is coded in a separate file. How do I use Incremental Design on a single file that contains several modules coded within it?

Solution

The Incremental Design process currently bases re-synthesis only on files that have changed. It cannot detect when one module in a single file containing multiple modules has changed. The whole file will be re-synthesized rather than the changed module.
