For our project we need a random number generator, which also needs to 
be synthesizable. So I used a linear feedback shift register (LFSR) to 
create a 13-bit pseudo random number generator.

However, it cannot be synthesized and I don't know really why and how to 
solve it.

Is that the error message from your synthesis tool? If not, is it a 
secret, or why don't you want to tell us the message?
