Configurable Hamming Generator

I tried to compile on Lubuntu for Powerpc with g++ 4.6.3. You have to add the lines
#include <cstring>
#include <string>
in the files hamm_sec_gen.cpp and hamm_secded_gen.cpp, because if you use "make" (like i did) the linker doesn't know how to use "strcpy". Maybe you have to use just one of the includes, IDK. I just wanted to run the generator.

Compiling failed on Linux

There are multiple cases where a double bit error is not detected, There is a bug opened against this but it is 4 years old, is the fix avaliable?
Is this project still active?

Double bit error not detected

It would be nice to have verilog output as a capability of the program.

I'm currently adding that support if you would like the code.

Verilog output

In VHDL function hamming_encoder_31bit lines end badly, without closing parenthises). This happens with only some hamming codes lengths, eg. 30, parity bit 3.

Could it be at line 259 in hamm_sec_gen.cpp?

Simple VHDL syntax error

It is problem in the syndrome generation ... It will be fixed soon.

SEC-DED is not detecting all double faults

improve the code to enable to correct more than 1 error
