4# This is Aaron's attempt at a MAGIC file for Xilinx .bit files.
5# Xilinx-Magic@RevRagnarok.com
6# Got the info from FPGA-FAQ 0026

8# Rewritten to use pstring/H instead of hardcoded lengths by O. Freyermuth,
9# fixes at least reading of bitfiles from Spartan 2, 3, 6.

12# First there is the sync header and its length

17>>>>&1   beshort =0x0001
18>>>>>&3	string	a	Xilinx BIT data
19# Next is a Pascal-style string with the NCD name. We want to capture that.
20>>>>>>&0	   pstring/H	x	- from %s
21# And then 'b'
22>>>>>>>&1    string b
23# Then the model / part number:
24>>>>>>>>&0   pstring/H    x       - for %s
25# Then 'c'
26>>>>>>>>>&1 string c
27# Then the build-date
28>>>>>>>>>>&0 pstring/H    x       - built %s
29# Then 'd'
30>>>>>>>>>>>&1   string d
31# Then the build-time
32>>>>>>>>>>>>&0  pstring/H x        \b(%s)
33# Then 'e'
