- # 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.

- # First there is the sync header and its length

- >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
