Questions

All,

 I need some clarification on the following :

  (1) When running simulations on an "input buffer with Bus-Hold" to extract cla mp
      data, should the bus-hold circuitry be disconnected ?. In other words,
      should we include the contribution from the Bus-Hold circuit in the clamp data.
      I would think not, any suggestions ?
  (2) Similarly, some of our devices have the so called Power-On-Demand (POD) fe ature
      on the output buffer. In a BiCMOS device, this feature works to reduce the
      base current in the pulldown transistor when the output voltage is below a preset
      level, thereby reducing power consumption. While this circuitry can be
      disconnected in a simulation, it is always present in real-life. Again, should
      the effect of such circuit be incorporated into the pulldown data ?.

 Please advise !
