Minutes from 01 nov 2005 meeting attached. ARs due:
AR: Mike fix EQ amp rcvr template
AR: Ian will draft a BIRD for analog-only AMS support in IBIS
AR: Mike add extrapolation warning to module documentation
I will be out next Tuesday, unable to attend. If everyone else decides
to carry on without me, we just need someone to take minutes.
Mike
meeting date: 01 nov 2005
attending: Arpad Muranyi, Ian Dodd, Todd Westerhoff, Mike LaBonte
Bob Ross, Ken WIllis, Shang Li
-------------
Review of ARs:
AR: Mike will annotate library modules
- XML files, PERL scripts, almost done
AR: Ken write simple receiver template
- done
AR: Ian will draft a BIRD for analog-only AMS support in IBIS
- In progress
-------------
Simple receiver
- Based on EQ amp rcvr template
AR: Mike fix EQ amp rcvr template
Draft BIRD
- Ian working with Arpad
- Will support Verilog-AMS, but allow for A/D and D/A
- specify required lo/hi V, and dt for analog inputs
- lo/hi V for analog output
- Discussion with Mentor analog sim people
- No Verilog support in SI tools
- Positive feedback so far
- Analog portion of Verilog is fuzzy
- 1999 standard, System-Verilog, etc.
- Ken unable to contact Cadence people yet
- Positive feedback so far
- Current macro library would be illegal under current IBIS
- BIRD probably ready in 2 weeks
AR: Ian will draft a BIRD for analog-only AMS support in IBIS
PWL extrapolation policy
- SE = slope extrapolation
- HE = horizontal extrapolation
- extrapolation option:
- On gives SE
- Off gives error messages
- V/T tends to be HE, everything else SE
- Can always flatten the ends in case SE is used
- flexibilty vs. compatibility
- Use HE for dependent-V, SE for all else?
- no, some dependent sources not ready for that
- IBIS parser assumes SE of I/V curves
- PWL VA code could check last 2 points at initialization
- For tool compatibility
- Not converging on this ...
AR: Mike add extrapolation warning to module documentation
Param arrays
- Cadence simulation is problematic
- HSPICE has same problem
- Re-write so tools can consume directly?
- Can cut & paste inot model instead of using external
- PERL script could do it
Triggerable source
- Earlier decision was to do this later
- Arpad running into it now
- Tlsim is the only implementation
-------------
Next meeting: Tuesday 08 nov 2005 (Mike can't make it).
