I did check out the XST document. I guess that would be a good enough
guide to know if the code would be synthesizable.. And surprisingly it
does mention the use of $readmemh.. I tried to create a ROM model and
initialized it using a .mem file... It does not throw any error in the
synthesis report.. But somehow it doesn't initialize it correctly
either.

I have another question.. I need to design a block interleaver.
Contents of input buffer are written to an output buffer. The
challenge is to do it in one clock cycle- for which i will need a very
large buffer. The problem is i need to create a matrix of buffers
( possibly 16*6) and read in one go.. Any suggestions ? How do i
normally go about designing a multi dimentional buffer.
