New Discussion:

Standard Power Integrity Model (SPIM) BIRD draft:
Kinger briefly reviewed the new draft (draft5) and noted that it contained all
off the modifications discussed at the previous meeting (see minutes from the
November 15, 2022, meeting).

Kinger and Arpad asked people to review the draft and provide feedback.

PSIJ Sensitivity BIRD:
Kinger briefly reviewed the new draft (draft3).  He noted that this version
introduced the new [PSIJ Voltage List] keyword, as opposed to reusing the
existing [Voltage List] keyword, per the discussion at the previous meeting.

Kinger noted new language recommending that a cubic spline be used to fit the
[PSIJ Sensitivity] data, per Randy's comment at the previous meeting.  Randy,
Bob and Arpad said we have to be careful to ensure that this section defines the
requirements for the model maker and the EDA tool.  For example, the model maker
should choose the frequency points provided in the [PSIJ Sensitivity] keyword in
order to define the worst-case PSIJ sensitivity envelope over the required
frequency range, and the EDA tool should use a cubic spline to fit the discrete
data points.  Kinger said he would make changes to this section of text and send
a draft4 to the ATM list.

- Curtis: Motion to adjourn.
- Randy: Second.
- Arpad: Thank you all for joining.

AR: Kinger to send an update (draft4) of the PSIJ Sensitivity BIRD to the ATM
    list.
