Hi Pete,
Thank you for your LUT-based BM!
I'm trying to implement the tutorial
on:
http://elektronica.ehb.be/reco/PartialTutorial.htm onto a Virtex 4
(FX12) using LUT-based BM.
But I couldn't assembly.
If I don't use the fake Gnd and Vcc, PAR gives me the following error:
FATAL_ERROR:Guide:basgitaskphyspr.c:372:
1.28.20.4:286 - A previous module
has placed the comp: capture/PWR_GND_0 on the same site: SLICE_X37Y81 where
the current guide comp PWR_VCC_0 also needs to be placed. There exists at
least two guide files that contain logic 0/1 signals being driven from the
site location. Process will terminate. ....
If I use the fake VCC and GND, PAR gives me the following error:
FATAL_ERROR:Guide:basgitaskphyspr.c:333:
1.28.20.4:137 - Guide encountered a
Logic0 or Logic1 signal GLOBAL_LOGIC1_6 that does not have a driver or
load within the module boundary. This problem may be caused by having a
constant driving the input from outside the module boundary or because a driver
or load comp did not meet the par-guiding criteria. The design
will not be completely placed and routed by Par-Guide Process
will terminate.......
It seems you are doing reconfiguration on Virtex 4. Do you have any
idea about this? Or maybe you could send out a tutorial about DPR on
Virtex 4. People would be moved to tears...
Thank you.
