All,
The review and vote to approve the requirements for Table Driven Modeling in VHDL-AMS closed last Sunday with the following result:
Eligible voters: 5
Votes returned by eligible voters: 4
Votes received by ineligible voters: 4
The reviewers/voters were: David Bishop, John Shields, Subramanian Sivaramakrishnan, David Smith, Alain Vachoux, Arpad Muranyi, Joachim Haase, Ernst Christen
All returned votes were affirmative, some with comments included below. With this result the requirements for Table Driven Modeling have been approved.
The comments returned by the reviewers/voters were:
David Bishop:
VHDL already supports much of this syntax.
I am the author of the fixed and floating point VHDL-2008 packages, and
I am working on the matrix math package. Could you use my help?
Subramanian Sivaramakrishnan
My comment is on the history part .
v0.5.
TDM-R5: requirement on complex dependent variable added’.
This item really appears to be related to TDM-R6 rather than TDM-R5 .
Arpad Muranyi
TDM-R2 [shall]
The package(s) shall support lookup function(s) for time-domain and
frequency-domain simulation.
I believe, we should also support QUIESCENT_DOMAIN, because
before simulators usually do QUIESCENT_DOMAIN before each
TIME_DOMAIN or FREQUENCY_DOMAIN, and the operating point
found during a QUIESCENT_DOMAIN simulation can be crucial
for how the simulation following it continues. If we
didn't support QUIESCENT_DOMAIN, the operating point may
be completely different from what would be desired or needed
and as a consequence the results could be incorrect, or there
may be a huge discontinuity between QUIESCENT_DOMAIN and the
first iteration of TIME_DOMAIN, for example.
TDM-R14 [should]
At least the following existing (de facto) standard text-based file
formats should be supported: Verilog-AMS, Touchstone, IBIS, Excel CSV.
Rationale: The package definition and reference implementation should
support the interoperability with related existing (de facto) standards
such as Verilog-AMS, IBIS, Modelica, and Excel CSV format. There is no
need to define yet another file format. The package(s) shall work on an
internal data structure whose content is semantically related to the
data stored in files. The list of supported file formats may need to be
updated and prioritized.
This is just a minor observation, but the list in the first
paragraph is different from the list on the second paragraph.
Modelica is no listed in the first... I wonder if this was
an intentional difference or just an oversight.
