- Behavioural model is must for simulation tool.
o Behavioural
model is necessary for simulation tool to do functional checks . From DB it cannot
retrieve functionality of that DB cell.
o DB
cell is required mainly to get PG pin related information as in non-power aware
behavioural model you will not have PG pin information.
- DB information is optional .
o If
corresponding DB cell info is not provided than DB related checks will not be
performed on that module and will be treated as simple Verilog module.
- Below points can be considered as general guideline.
o If
user have non-power aware behavioural model for DB cell , provide both DB info +
behavioural model to simulation tool.
o If
user have Power aware behavioural model for DB cell , Only behavioural model is
enough ,provided you do not want to do any DB related checks on it.
