From clarification in requirements spreadsheet @ 3/3/2011
"DUOLOG via martin: DEFER
SNPS: Not supported by modelling languages
AGNISYS: Register model in IP-XACT is not dependent on any particular modeling language."
From clarification in RWG 3/31/2011 (from comments in the meeting)
"Use of lsb0/msb0 is preferred to bit endianess.
IP-XACt is lsb0 throughout.
To add msb0 for registers would create a large amount of change and potential for confusion, whereas msb0 can be derived from lsb0 (and vice versa)
It was agreed that annotation the IP-XACT in some way to show if the display should be lsb0 or msb0 (default lsb0) would be helpful."
--> requirement could be restated "To capture the bitendianess (lsb0,msb0) intended in IP-XACT, while continuing to represet as lsb0 in IP-XACT"
From Martin Baynes 3/31/2011
"SystemRDL uses the notation msb0, lsb0 para 7.2 and defines which is the mode for a addressmap in para 10.3
An addressmap in SystemRDL is also a leaf component in IP-XACT (see Para 9) - 'definines the RTL implementation boundary'
--> the property to track lsb0,msb0 display should probably be attached to the component view."
