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 December 12, 2011 meeting. The January 16, 2012 meeting was canceled.

Status of the reference implementation v0.9 using VHDL 2008

Details concerning the status are shown in the meeting slides (ppt). Implementation of the package body is based on VHDL 2008.

The subsequent topics were discussed and shall be considered in the next version of the reference implementation:

• For PREPARE_TABLE_DATA functions that read data from a file, an additional argument and corresponding type shall be provided. File formats (such as Touchstone, ...) shall be described by this parameter.
• The DEPENDENT_SELECTOR in the case of complex-valued one-dimensional interpolation shall point to a group of two columns that decsribe a complex number.
• A type REAL_MATRIX (available in VHDL 2002) instead of REAL_VECTOR_ARRAY (only available in VHDL 2008) shall be used to provide data for multi-dimensional interpolation.

An important question for the further activities is whether the types TABLE_DATA_REAL and TABLE_DATA_COMPLEX must be fixed by the package header or can be modified by implementors.

Status of the reference implementation v0.9 using VHDL 2008

A proposal for the documentation is provided by tdm_v0.9_doc_proposal.pdf.

Next meeting

The next web meeting is planned on Monday, March 5, 2012 at 8am PDT or 17:00 CEST.

AOB

None.

Adjourn

Joachim adjourns the meeting at 18:25 CEST.

Action items

Ernst:

• Contact to ISAC (VHDL) concerning the declaration of types TABLE_DATA_REAL and TABLE_DATA_COMPLEX (opac ? or not).

Joachim:

• Update of the reference implementation using VHDL 2008
