2014.1 Vivado - Does the read_checkpoint command initialize .link the design?

Description


When I import the a routed design checkpoint (dcp) file with read_checkpoint command, as in the example below, is the design initialized?

read_checkpoint bft_routed.dcp

Solution

In Vivado releases up to 2013.4, read_checkpoint will automatically initialize a design.

In Vivado 2014.1, read_checkpoint will not automatically initialize a design.

Please use link_design to initialize a design after reading one or more checkpoint files.

This change was implemented in order to make the read_checkpoint command more in line with other "read*" commands. 

Vivado 2013.x software issued the following informational message regarding this upcoming change.

INFO: [Vivado 12-3496] In future releases read_checkpoint will not automatically initialize a design.
Please use link_design to initialize a design after reading one or more checkpoint files.
Alternatively, to initialize a design with just this checkpoint file, the open_checkpoint command can be used.
