Foundation F1.5: Important information about source and revision control in HDL projects
Problem Description:
Urgency: Hot
General Description:
Foundation F1.5 is the first Xilinx release with the integration of Synopsys
FPGA Express technology. There are a few things that need to be explained
completely about source and revision control.
Solution 1:
The Foundation Project Manager does not maintain backups of any source HDL
files. Therefore, it is up to the user to periodically save any source files
to a separate directory if the user wishes to maintain backups.
Furthermore, the Foundation Project Manager does not maintain intermediate
netlist files. Even though a project may contain multiple Versions of a design,
there will always be only one XNF file (or EDF, in the case of Virtex).
So, if you synthesize a design targeting a 4000e device, and then re-synthesize
the design targeting a 4000xl device, you will have two unique Versions.
However, you will have only one XNF file, and that will match the most recent
synthesis run (the 4000xl in this case). If you go back to the first Version
(4000e) and select Implement, you will place and route the 4000xl version.
This behaviour has been updated with Foundation F1.5i. Whenever you select
Implementation to place and route the design, a new XNF/EDF file will be
exported. The version control feedback has been greatly improved with this
release.
