All component inputs are initialized when running in has_assignments() mode, and normal copy_constraints are created. However, in generate-type circuit mode, some steps are skipped, and copy_constraints are created with uninitialized w(0,0) cell.
[ ] fix this issue
[x] add tests to control that everything works as intended
