MM,
Significant suggestions for Slide 5 and 8
Walter
Slide 5
* Any useful interconnect improvement proposal must support.
- Coupled and uncoupled I/O models
- POWER and GND models
- Coupled I/O and POWER and GND models
- Clear identification of aggressors and victims in coupled sims
- IBIS-ISS and Touchstone models
- Models can be from pin to buffer or can be split into package and
on-die interconnect
- Connections without requiring legacy package keywords
- Explicit identification of interconnect terminals by pin_name,
signal_name or even [Pin Mapping] bus_label
Slide 8 split into two slides
Interconnect Models and Model Sets
Designed to Support the Way Package
and On-Die Interconnect Models are
Generated and Delivered Today
- Identify whether a coupled signal is only an aggressor or also
"experiences" coupling from all other sources
Slide 8a
* Interconnect Model Sets
- Any Grouping Interconnect Models
- Can have separate Interconnect Model Sets for different
interfaces
* DDR Memory subsystem
* PCEi Bus
* Power
- Can have separate Interconnect Model Sets for coupled simulations
- Can have separate POWER and GND Interconnect Model Sets
* Simple POWER and GND with each POWER and GND signal names lumped into a
single terminal at the Pins and on the Silicon
* Detailed POWER and GND with a terminal for each POWER and GND pin, and
POWER and GND rail connection at each I/O buffer.
* Middle ground where groups of pins (bus_labels) are connected to a
single terminal.
