Hello, every one,

I have a problem.

When I connect the sub-block scan chain on top design. On the wrapper of this sub-block will be generated net test_si ports, the test_si ports I created earlier on wrapper are not used and tied 1'b0.

Please see the picture.
 

you should connect these by RTL code.
then when you do bottom-up synthesis strategy.
on top. you only to merge the sub chain to do connect only.
