In reply to Jung Ik Moon:

You can create a package for all the blocks, or create a package for each block. It does not matter if you define a register block but do not use it.

package BlocksABC; 
  - Block A
    - Register a
  - Block B
    - Register b
  - Block C
    - Register C
endpackage
package IP_ABC;
 import BlocksABC::*:
  -BlockABC
    -instantiate A
    -instantiate B
    -instantiate C
endpackage
package IP_A;
 import BlocksABC::*:
  -instatiate A
endpackage
