Editing Implementation Constraints
Creating a New Version
If you want to implement a new version of the design (after the initial
implementation), you must first create the new version by selecting
Project
dialog box that has the same fields as the Implement Design dialog
box. The version name is automatically entered. Modify the names,
control files, and/or options and run the Flow Engine as described
previously for the first version/revision.
Constraints are instructions placed on symbols or nets in a schematic
(or textual entry file such as VHDL or Verilog). They affect how the
logical design is implemented in the target device. Applying
constraints helps you to adapt your design’s performance to expected
worst-case conditions. The user constraint file (.ucf) is an ASCII file
that holds timing and location constraints. It is read (by NGDBuild)
during the translate process in the Flow Engine and is combined with
an EDIF or XNF netlist into an NGD file.
