Hi Walter,
I'm working on my stacked-die example using the EMD syntax. Here's some
feedback I have so far as I've been reading through Draft 21.
Given that we have this rule:
Only one [Begin EMD]/[End EMD] keyword pair is allowed in a .emd file.
I don't think the highlighted text is necessary:
Keyword: [End EMD]
Required: Yes
Description: Marks the end of a module.
Usage Rules: This keyword must come at the end of each complete module
description.
Optionally, A comment may be added after the [End EMD] keyword to clarify which
module model has ended.
Example:
[End EMD] | End: 16Meg X 8 SIMM Module
Also, I think that the Example on pages 25-26 can be modified to include the
[Designator Pin List] section instead of the commented [Component] pin list.
Replace:
| The following will not exist, but is used to explain the examples below
| [Component Pin List] signal_name signal_type
| U1.1 VDD POWER VDD1
| U1.2 VDD POWER VDD2
| U1.3 VSS GND
| U1.4 VSS GND
| U2.1 VDD POWER VDD1
| U2.2 VDD POWER VDD1
| U2.3 VSS GND
| U2.4 VSS GND
With:
[Designator Pin List] signal_name signal_type bus_label
U1.1 VDD POWER VDD1
U1.2 VDD POWER VDD2
U1.3 VSS GND
U1.4 VSS GND
U2.1 VDD POWER VDD1
U2.2 VDD POWER VDD1
U2.3 VSS GND
U2.4 VSS GND
With this change, I think it's necessary to expand the [Designator Pin List] to
include the signal pins on U1 and U2, for at least DQ1 that has the [EMD Model].
Thanks,
Randy
