Action items from February 7, 2011 meeting Multi-dimensional Interpolation/Extrapolation (by Ernst Christen) http://www.eda.org/twiki/pub/P10761/ProjectTableDrivenModeling/interpolation.txt Test implementation v0.3 (multi-dimensional interpolation/extrapolation included) http://www.eda.org/twiki/pub/P10761/ProjectTableDrivenModeling/tdm_v0.3.pdf

Discussion concerning action items on multidimensional interpolation (1)

Discussion concerning action items on multidimensional interpolation (2) INTERPOLATION_ND function INTERPOLATION_ND ( XV : REAL_VECTOR; X : REAL_MATRIX; Y : REAL_VECTOR; METHOD : INTERPOLATION_METHOD_VECTOR; LEFT : EXTRAPOLATION_METHOD_VECTOR; RIGHT : EXTRAPOLATION_METHOD_VECTOR ) return REAL; No initialization

Discussion on further activities (1) Phase 2: Discussion of VHDL(-AMS) implementation aspects Phase 3: Definition of VHDL(-AMS) function headers and standard package header Basic Interpolation Functions Package TABLE_INTERPOLATION_PKG Basic functions INTERPOLATION_1D (real- and complex-valued) How to test characteristics of 1D-complex-valued interpolation ? INTERPOLATION_ND Functions with preordered data Provide ppforms for 1D interpolation Provide ordered data for ND interpolation

Discussion on further activities (2) Functions to provide data for basic functions For instance read in from files Discussion was delayed during the last meeting Collection of ideas Preparation of of test cases

Proposal for action items Declaration of function headers for basic functions Collection of test-cases

Next meeting Monday, April 4, 2011 – 8am PDT (UTC-7) = 5pm CEST (UTC+2) Summertime in US and Europe
