Review of ARs:

- no ARs from last week

-------------

- Mike will post Arpad's files to the website archive area as-is.
- Documentation
- Changes:
  - Typo in the divider module fixed.
  - Break statement added to tell simulator when there is a discontinuity
    switching over to the NearZero algorithm (avoids divide-by-zero).
    - It would be good to have some user warning when the NearZero algorithm
      is triggered.
  - Event riggered modules:
    - HSPICE use different methods for DC and AC analysis
      - DC assumes high state above .5 V
      - AC uses 0.2V and 0.8V to add hysteresis
    - Order of execution is critical in VHDL-AMS
      - Gets "stale" EventState value

Cadence proposal
- Still waiting for details of API.
- Probably should not standardize on convultion channel analysis approach.
- API accepts waveform in, does DSP and puts out new waveform.
- API module needs to know what simulator does to be able to interface.
- TI simulates bit-by-bit (not convolution) using parallel simulation.
- A powerful API definition should be able to support both circuit and
  convolution simulation.
- Using [External Circuit] is a good idea.
  - Add ExecutableAPI as a simulator name.
- Kumar pointed out that existing APIs do not support vector processing.
- Would be nice to define an API that could do other types on anylysis:
  - eg. simulating bits with random jitter until a certain BER is achieved.
- How important is assumption of linearity in convolution simulation?
  - Practical assumpotion that makes the math work.
- Don't want to standardize the technique because something better may
  come along.
