Joachim welcomes Ernst and starts presenting the [[%PUBURL%/%WEB%/ProjectTableDrivenModeling/1076.1_table_driven_modeling_2011_05_02.ppt][meeting slides]].
---+++ Volunteer for minutes

Joachim takes the notes.
---+++ Approval of agenda

Agenda unanimously approved.
---+++ Review and approve minutes from last meeting

Ernst agreed to approve the Minutes of the April 04, 2011 meeting.
---+++ Discussion on VHDL-AMS implementation aspects

Based on the discussion during the last meeting material on "Table-Driven Modeling in VHDL-AMS - Summary" ([[%PUBURL%/%WEB%/ProjectTableDrivenModeling/2011-04-29_tdm_procedures.pdf][pdf]]) was prepared. It summarizes the current status of the discussion.

It was discussed whether different declaration for a TABLE_DATA_REAL type for the one- and multi-dimensional cases are necessary. Some Pros and Cons for one type can be found in the meeting slides. The final decision was delayed. The test implementation should start with one declaration for both cases.

A permutation vector for characterizing given data (innermost and outermost dimensions) in the case of multi-dimensional interpolation should be avoided. The data for the real-valued multi-dimensional interpolation should be provided similiar to the Verilog-AMS. Special function interfaces should be provided for preparing the 1 ... 4-dimensional case. They might look like
   * PREPARE_DATA (X : REAL_VECTOR; Y : REAL_VECTOR; ... ) <br />return TABLE_DATA_REAL;
   * PREPARE_DATA (X0, X1 : REAL_VECTOR; Y : REAL_VECTOR; ... ) <br />return TABLE_DATA_REAL;
   * ...
   * PREPARE_DATA (X0, X1, X2, X3 : REAL_VECTOR; Y : REAL_VECTOR; ... ) <br />return TABLE_DATA_REAL;

In the multidimensional case, an appropriate type to describe the independent X values based on vectors for each dimension has to be used. It should be checked whether an appropriate is provided by the Vector/Matrix package.
