Now that you upgraded all the IP to the latest version, you can optionally setup and launch out-of-context synthesis runs for the IP. You already configured the Clocking wizard IP to not use the out-of-context flow in Step 5.
The FIFO Generator IP already had all the output products, including the DCP, generated when it was imported. However, the Block Memory Generator and Accumulator IP have not had any output products generated.
In a project flow, if the IP is current then all the output products, including the DCP, are generated automatically. However, you can also script this step. One reason to manually create and launch design runs for the IP cores in a project is to have the out-of-context synthesis processes run concurrently. By default, they are launched serially.
