Hi @bsunanda
I'm not sure I understand the PR title and description. Is it to add a test, or something else? Thanks.

[bsunanda]

@srimanob We have been struggling to find the reason of failure of Phase2 scenario in dd4hep. We use different codes for the algorithms and the main purpose of this PR is to see if the 2 sets of algorithms used for V14 HGCal give the same results. There are debug statements which are made similar outputs. Running the codes separately for silicon cells, wafers, full silicon layers, mixed layers and comparing the two sets of outputs using diff show identical results from ddd and dd4hep. This required changes in the debug statements, defining a few cdi's, cfg's which are parts of this PR

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)
