I have a block diagram project that integrates my own custom block diagram. I've made some recent changes to my custom block and to integrate these changes with the top level project, I follow a three step process:
1. I refresh my IP repositories
2. I run 'report_ip_status'
3. I run 'upgrade_ip [get_ips *]
I've noticed when I run the last Tcl command, I get a number of info lines that say, e.g.
... and a bunch of other lines that start with 'Adding cell' referring to all the IP in my design. I could swear that I have not seen this 'Adding cell' set of steps in previous efforts to upgrade_ip. What does it mean when the tools try to add all these cells back to the design?
