Technical topics

Brief summary of discussion, pros and cons, and conclusions

GB describes to the workgroup the functional modules design as documented in see WG1 : Data, arithmetic, and expressions#Functional module calls

SE raises the potential problem of non-terminating modules. It seems if it is called in an emit, it shouldl be combinational, and this constraint couldl be relaxed if called in a sustain for instance. To be analyzed.

Working Group WG2: signals, interfaces, ports

  • Eric Badi, Badr Bentaybi, Gerard Berry (organizer), Jean-Philippe Cousin, Reinhard von Hanxleden, Klaus Schneider, Claus Traulsen,.

  • GB explains the current design and difference between default and init. In particular it has the nice property that control signals can be seen as data signals. Olivier remarks that there may be a problem in semantic rules. OT will check andn update wiki accordingly.

  • the extends - observe proposal is discussed. Question about extends with signals removing.

  • RB: proposal to replace '''reg''' and '''mem''' in signal declarations. See Talk:Esterel_v7_Tex_LRM_Signals_and_Interfaces_chapter#A completely different alternative syntax proposal. To be discussed on the wiki.
