dpl: add LEF symmetry to dpl and dpo

[rafaelmoresco]

Closes #9238

Current DPL and DPO ignore the allowed symmetries indicated in the LEF file.
Added symmetry checks for every movement attempt in DPL and DPO.

Code Review

This pull request introduces LEF symmetry checks in DPL and DPO, which is a valuable addition. The implementation is mostly correct, but there are several instances of code duplication that should be addressed to improve maintainability. I've provided suggestions to refactor the duplicated logic into helper functions and to simplify some of the new checks. Addressing these points will make the code cleaner and more robust.

This logic to calculate masterSym is duplicated in Place.cpp, detailed_manager.cxx, and twice in this file. To improve maintainability and reduce code duplication, you should extract this into a new static helper function within the DetailedOrient class.

For example, you could add the following to detailed_orient.h:

static unsigned getMasterSymmetry(odb::dbMaster* master);

And implement it in detailed_orient.cxx:

unsigned DetailedOrient::getMasterSymmetry(odb::dbMaster* master)
{
  unsigned masterSym = 0;
  if (master->getSymmetryX()) {
    masterSym |= Symmetry_X;
  }
  if (master->getSymmetryY()) {
    masterSym |= Symmetry_Y;
  }
  if (master->getSymmetryR90()) {
    masterSym |= Symmetry_ROT90;
  }
  return masterSym;
}

Then, you can replace this block and other occurrences with a call to this new helper function. For example:

• Here and in orientSingleHeightCellForRow: unsigned masterSym = getMasterSymmetry(ndi->getDbInst()->getMaster());
• In detailed_manager.cxx: unsigned masterSym = DetailedOrient::getMasterSymmetry(nd->getDbInst()->getMaster());
• In Place.cpp: unsigned masterSym = dpl::DetailedOrient::getMasterSymmetry(cell->getDbInst()->getMaster()); (you'll need to include optimization/detailed_orient.h).

  auto* dbMaster = ndi->getDbInst()->getMaster();
  unsigned masterSym = getMasterSymmetry(dbMaster);

@maliberty is there any problem in using the DPO symmetry checker in DPL like gemini suggested?
