Libero IDE v9.1 generates .bit file as programming file for ProAsic and ProAsicplus devices. Each line of the .bit file consists hexadecimal values. E.g. 000000000000000000000000000000000000FFFFFFFFFFFF0000FFFFFFFFFFFF0000000000000000000000000000000000000000800000000000FFFF7FFFFFFF4001FFFFFFFFFFFF0888000000000000

I want to understand how the HDL code is converted to bitstream which consists the numbers alone. Is any mapping technique is available to understand the bitstream??
 

Whoa.

The bitstream is used to map the internal connections of the device, and is quite far removed from the HDL. There is no direct connection between the two; HDL code is not "converted to bitstream", there are several intermediate steps-synthesis, mapping, placement, routing.
