Alain volunteers to take notes.

Approval for agenda

Agenda unanimously approved.

Minutes from last meeting

Minutes of September 13, 2010 meeting unanimously approved.

Current action items


  • Update requirement document from the meeting discussion. version 0.5 published on web site

Information regarding the voting process of the requirements document

Ernst reports that he received a few votes. All are positive with one editorial comment. Ernst will recall the deadline of October 17 to the WG.

Preparation of phase 2

Points raised when discussing slides 8-11:

  • No need to require that the distance between two data points (x(k) - x(k-1)) must be constant.
  • The complex_vector type is not yet available as a standard type (must be probably declared in IEEE 1076.2).
  • Quadratic spline and cubic spline interpolation methods: a practical approach is to define endpoint conditions using the selected extrapolation method.
  • Natural cubic spline interpolation method: A useful requirement if no extrapolation method is given is that the 2nd order derivatives at endpoints are zero.
  • Complete and natural cubic spline interpolation methods are supported in Verilog-AMS. Not-a-Knot cubic spline method is supported in Matlab/Octave.
  • Next step should be an inventory of possible/realistic combinations of interpolation/extrapolation methods and from that defining which methods/conditions are actually involved.
  • Multi-dimensional case should be adressed once the uni-dimensional case has been thoroughly reviewed.

Next meeting

The next telco is planned on November 8, 2010 at 8am PDT or 5:00 CEST.




Joachim adjourns the meeting at 6:00 CEST.

Action items


  • White paper on possible/realistic combinations of interpolation/extrapolation methods for one-dimensional case.
