# First there is the sync header and its length

0 beshort 0x0009

>>>&0 beshort =0x0000

>>>>&0 pstring a Xilinx BIT data
|
# Next is a Pascal-style string with the NCD name. We want to capture that.
|
>>>>0x0F pstring x - from %s
|
# It is followed by a NUL
|
>>>>>&1 byte 0x00
|
# And then 'b'
|
>>>>>&2 string b
|
# With the part number:
|
#>>>>>&5 string 4v (Virtex4)
|
#>>>>>&5 string 2v (Virtex II
|
#>>>>>>&0 string !p \b)
|
#>>>>>>&0 string p Pro)
|
>>>>>&4 pstring x - for %s
|
# And then NUL / 'c' / Build Data / NUL / 'd' / Date / NUL / 'e' / Data Length
