Level-shifter cells are removed after placement

manpmanp

Hi there!

In my design, I intend to have a power domain containing all level-shifter cells.

The Tool for synthesis is Synopsys Design Vision (K-2015.6-SP4) and the PNR tool is Cadence Innovus (v16.13) and technology ST 28FDSOI.

The steps I have taken towards this target:

1- using a clock buffer as the level-shifter component in LevelShiftDomain.vhd

2- synthesizing the design

3- CPF file containing all necessary details, such as powerDomains and their definition, all available level-shifter cells to use (define_level_shifter_cell) and rule to use them (create_level_shifter_rule)

however after place_design, cells  from level-shifter power domain are removed.

What is your suggestion to solve this issue?
