ADP-XC7336-Q
For Xilinx XC7318(-/A/Q), XC7336(-/A/Q), XC9536 and XC9536XL in QFP44.


There are multiple executables:
for ALL03 and XC7318(-/A/Q), XC7336(-/A/Q) it is Axc7236.exe
for ALL03 and XC9536 it is Axc9500.exe
ALL03 does not support XC9500XL series.

for ALL07 and XC7318(-/A/Q), XC7336(-/A/Q) it is Axc7236.exe
for ALL07 and XC9536 it is Axc9500.exe
for ALL07 and XC9536XL it is Axc95xl.exe

The RP1 on the schematic can be everything between 0R and 100R. I don't know what values
has been used on the original HiLo adapter, but based on Xilinx Programming Specification it have
to be 0R for XC7xxx series up to "soft GND" (pulldown) for XC9500XL series.
On my test adapter i have used 0R, that worked with all CPLDs.

There is bug in HiLo ALL07 software Axc95xl.exe, v3.01 . One can select (8) XC9536XL (VQFP44)
but this is actually for VQP64 version. Older versions of Axc95xl.exe does not support XC9636XL in QFP44 at all.
To program them one have to wire QFP44 IC to PLCC44 and select then XC9536XL (PLCC44) in the Axc95xl.exe.

There seems to be bug in Axc9500.exe executable, one can not burn "write secure" fuse on XC9536.
In the Xilinx XC9500 Programming Specification one can read that :

If the user elects to use both Read and Write Secure, the Read Security addresses must be
programmed first, followed by the Write Security addresses. Do not power down between
programming of the Read and Write Secure addresses or between Program and Verify operations.

However the Axc9500.exe executable is allowing only "read secure" in Auto mode, but no "write secure".
When selected manually from "Security fuse blow", the "write secure" is not running "read secure" first (as described above),
but only doing the "write secure" which of course fails. Luckily "read secure" is the typical kind of security fuse that one need:

The device supports two types of security; one to protect the design from being copied (read secure),
and one to protect the device from being erased and/or reprogrammed (write secure).
