Call to order

Agenda was approved without changes.

Administrative issues

Approval of minutes
Minutes of the 2016-09-07 meeting were approved. Alain moved, seconded by Joachim.

Review of IEEE patent policy
Review of patent policy was skipped because all participants in the telephone conference were regulars.

Handling of copyrighed material
Ernst received a Copyright Permission Letter from Cadence and Eastman Kodak. Synopsys and Accelera are working on it.

Project discussion

TDM and VMO packages
Table Driven Modelling (TDM) package shall be provided under an Open Source copyright. The same will be recommended for the Vector Matrix Operations (VMO) package. Further details can be found in the meeting slides..

LCS 201x-21 Transfer Functions
The LCS 201x-21 was revised. There is no easy way to overcome the problems that were addressed in the 2016-09-07 meeting. Details can be found in the meeting slides.. It was discussed to add a note into the LRM that gives a hint on how to overcome numerical problems with the existing declaration of `LTF and `ZTF attributes.

In the past, a problem was observed with the Q`SLEW attribute at discontinuities. It should work in the same way as S`SLEW where S is a real-valued signal. To adjust the behavior, Ernst presented a proposal on how to solve the problem. Further details can be found in the meeting slides.

LRM status and next steps
The LRM status and next steps are summarized in the meeting slides.. Ernst will inform the WG about the status of the LRM process and the schedule for LRM review and approval by the WG and formation of a balloting group.


There was no AOB.


The meeting ended at 9:25 am PDT.
