+1. `accumulator.v` - 20 bit accumulator 
+2. `adc2to3bit.v` - Two to three bit mapping of the input data
+3. `clk_gen_gps_new.v` - Module containing NCO for Carrier Generation and code clock generation
+4. `codectrllogic.v`- Topmost module for generation of three versions of Goldcodes (Early,Late,Prompt)
+5. `codegen.v` - Goldcode instantiation module
+6. `goldcode.v`- Goldcode generation module based on the Satellite ID
+7. `gps_multichannel.v` - Topmost Module containing 8 single channels and address decoding
+8. `gps_single_channel.v` - Single channel module containing all module instantiations and Wishbone Interface
+9. `signmag_twocomp_vv.v` - Sign Magnitude to Two's complement Conversion
+10. `signmul.v` - 3 bit Sign Magnitude Number multiplier
+11. `thresh_control.v` - Threshold check block to generate Carrier change pulse to invoke Doppler
+12. `threshold.v` - Threshold check block to check whether the satellite is acquired or not
+13. `track_intganddump.v` - Gold code multiplication with Integrate and dumping of 6 signals(3 - i and 3 - q)
+14. `wb_interface.v` - Provides interface between 32-bit wiishbone bus and internal blocks . Through this wishbone interface , software can write and read memory mapped registers . The details of the wishbone registers is mentioned below .
