In timing driven placement the repairDesign part of the resizer is called which exercises the "makeRepeater" method. This pull request adds hierarchical support to the makeRepeater method. The key changes are:

  1. Support for hierarchy in makeRepeater (method in repairDesign)
  2. New generic api for connecting pin to net in dbNetwork -- connectPin which will allow any pin/net (hierarchical or other)
  3. Addition of a net naming function to resizer which uses scoped naming (fixes minor latent issue) in hierarchical mode.

Do you expect this to have any impact on the non-hier flow?

no. Please note I am seeing some failures in the regressions on the pull request (I don't see any locally here -- all the regressions pass on my version of ubuntu), so am digging !

Have marked the pull request as draft until I figure out why the regressions on other versions of ubuntu failing (am seeing some valgrind issues which I will dig into).
