# This is Aaron's attempt at a MAGIC file for Xilinx .bit files.
# Xilinx-Magic@RevRagnarok.com
# Got the info from FPGA-FAQ 0026
#
# Rewritten to use pstring/H instead of hardcoded lengths by O. Freyermuth,
# fixes at least reading of bitfiles from Spartan 2, 3, 6.
# http://www.fpga-faq.com/FAQ_Pages/0026_Tell_me_about_bit_files.htm
#
# First there is the sync header and its length
0 beshort 0x0009
>2 belong =0x0ff00ff0
>>&0 belong =0x0ff00ff0
>>>&0 byte =0x00
>>>&1 beshort =0x0001
>>>&3 string a Xilinx BIT data
# Next is a Pascal-style string with the NCD name. We want to capture that.
>>>>&0 pstring/H x - from %s
# And then 'b'
>>>>>&1 string b
# Then the model / part number:
>>>>>>&0 pstring/H x - for %s
# Then 'c'
>>>>>>>&1 string c
# Then the build-date
>>>>>>>>&0 pstring/H x - built %s
# Then 'd'
>>>>>>>>>&1 string d
# Then the build-time
>>>>>>>>>>&0 pstring/H x \b(%s)
# Then 'e'
>>>>>>>>>>>&1 string e
# And length of data
>>>>>>>>>>>>&0 belong x - data length 0x%x
# Raw bitstream files
0 long 0xffffffff
