Bulk Checks

The incompatible bulk check flags transistors, which have the bulk terminal-related supply incompatible with the related supply of its source or drain terminal.

• For a P-type transistor, a violation is reported in the following scenarios:
  • The voltage for the related bulk supply net is less than the voltage for the related source or drain supply net.
  • The bulk node is OFF compared to either the source or drain terminal that are fully ON in a particular supply state.
• For an N-type transistor, a violation is reported in the following scenarios:
  • The voltage for the related bulk supply net is more than the voltage for the related source or drain supply net.
  • The bulk node is fully ON compared to the source or drain terminal that are OFF in a particular supply state.
