SVF test vector injection - generating SVF files

[Johann Klammer]

Good morning,
I was trying to run some test vectors on an ATF1504ASVL_A44 CPLD.
Even found some BSDL files on the net(no Idea if they're correct, tho').

I have vectors like this:
V0001 NLLNLLNLNLL1NNNNNNNHNNNNNNNNNNNNNN0NNNNNNLLL*
V0002 NLLNLLNLNLL0NNNNNNNHNNNNNNNNNNNNNN0NNNNNNLLL*
V0003 NLLNLLNLNLL0NNNNNNNLNNNNNNNNNNNNNN1NNNNNNHLL*
[...]

They are generated from a verilog sim.

From those I tried generating SVF files like this:
[...]
SIR 10 TDI (055);
SDR 192 TDI (0000000000000000840101510401415145c1401045400411);

using sample/preload runtest and extest states.
When playing, it failed at the first vector.
There was an IDCODE check before that, and that worked, so the
communication seems ok.

Then I tried this:

...extest only...
It also failed at the first vector (with the same bitpattern read back)...

The program for generating the svf files is there:

What am I doing wrong?
(/Is/ there a way of doing it right?)

Can you share the error message if any and the tool environment?

Nevermind.. looks like I got the endianness wrong(again)...
