-mapstyle option in BATCH mode operation of XST

[Varun Jindal]

hello,

While running the XST in batch mode;

(by typing xst at command prompt) .. and followed by "help -arch
virtex -command run" .... this gives a list of all the synthesis
options available in the batch mode.

one of the options is -mapstyle... which has two options to select
from (LUT / Library) ...

this option is not described in software documentation, as well not
found in GUI.

Does anybody have any information regarding the purpose of this
option?

thanks in advance.

regards
Varun.
