Design checkpoints capture snapshots of your design in its current state. The checkpoint stores the netlist, constraints, and implementation results.
Use design checkpoints to do the following:
- Restore your design.
- Perform design analysis.
- Define constraints.
- Continue through the design flow.
Write design checkpoints at critical points in the flow for design analysis and constraints definition. Read design checkpoints to restore the design for debugging issues. A design checkpoint fully saves the design in its current implementation state.
You can run the design through the remaining flow using Tcl commands. However, you cannot add new sources to the design.
Note: Use the following Tcl commands to
write and read design checkpoints:
-
write_checkpoint <file_name>.dcp -
read_checkpoint <file_name>.dcp
open_checkpoint
<file_name>.dcp Tcl command. Refer to the
Vivado
Design Suite Tcl Command Reference Guide (UG835) for more details.
