/* Program Code */
// #1: ; KCPSM3 Program - Security control and design authentication.
// #2: ;
// #3: ; This program is provided for use with the reference design
// #4: ; 'low_cost_design_authentication_for_spartan_3e.vhd' implemented on the Spartan-3E Starter
// #5: ; Kit. The program provides design authentication control over the 'real' application as well
// #6: ; as providing features to enable evaluation of the design authentication method.
// #7: ;
// #8: ; Ken Chapman - Xilinx Ltd
// #9: ;
// #10: ; Version v1.00 - 1st November 2006
// #11: ;
// #12: ; This code communicates with the StrataFLASH memory to implement a design authentication
// #13: ; algorithm which then enables the main application design in various ways. To facilitate
// #14: ; evaluation of design authentication this design also interacts with the LCD display
// #15: ; and PC (via UART based RS232 link) to indicate authentication status and allow control
// #16: ; over the authentication validity of the design. Therefore this program includes:-
// #17: ;
// #18: ; 1) Code required to check authorisation which would be included in a production design.
// #19: ; 2) Code required to program the authentication value into FLASH memory which would
// #20: ;    typically only be implemented in a special design used at a secure programming
// #21: ;    facility as part of the production programming procedure.
// #22: ; 3) Code to allow you to see what is happening at all stages which is code that should
// #23: ;    never be included in a real production design as it reveals secrets that should remain
// #24: ;    hidden in order to make the task of breaking the security as difficult as possible.
// #25: ;
// #26: ; IMPORTANT - Feel free to use this code as a reference for your own security scheme but
// #27: ;             never use this code unmodified.
