3.1i XST- Net names are not preserved, even when using the KEEP attribute (KEEP attribute doesn't work).

Description


General Description:

I am trying to put an ECS or HDL design through XST. I would like to preserve my net names so that they are the same in the design and netlist.



However, even if I put a KEEP attribute on the net, XST changes the names.



(NOTE: This problem is fixed in the 4.1i software release.)

Solution

The KEEP attribute does not work in XST. Therefore, there is no way to prevent the nets from being renamed when they go from your design to the netlist.
