What is a BIT file?

File generated by BitGen, a program used for generating bitstreams required by Xilinx FPGAs (field-programmable gate arrays); saved in a binary format and contains the configuration information for the circuit; used for uploading the configuration data to the FPGA device, which can be completed using the iMPACT GUI provided with the Xilinx software.

More Information

BIT files are one of the files generated in a sequence of files used for designing and configuring an FPGA. For example, a Verliog (.V) HDL design file can be used to generate an .NGC netlist file, which is then converted into a .NGD file, and then from the NGD file to a bitstream BIT file.

NOTE: The BitGen program is included with the Xilinx ISE software package.

.BIT File Association 2

A BIT file is an encrypted data file created by FinalCrypt, a program used to encrypt and decrypt personal files. It contains a file, such as a .JPG image or .WMV video, that has been encrypted for security purposes.

More Information

BIT files are created by FinalCrypt and can only be opened by FinalCrypt using the cipher file used to encrypt the BIT file. Data in a BIT cannot be recovered without the cipher file, so it is important that it is stored in a safe location and backed up.
