hi,

I want to generate a 32-bits independently and uniformly distributed random binary number prbs[32:1]. One method is to use 32 seperate LFSRs to generate.
Could anybody can give some simple solutions?

What is your desired PRBS length?

LFSR is the most simple pseudo random generators and it gives a psuedo-random white sequence, other techniques will generate other kind of random sequence it depends merely on the application, kind of random sequence (guassian,white ..), and PRBS length.
so what do u need ?

Hmmm... What is your trigger? If it's totally non-related to your systems clock, and your system clock is much higher then your trigger event, you could just use a counter.

if you want to gen a prbs with len of 2^32-1, in fact, 32 bit registers is not a must. in fact, you could shift more than 1 bit per clock cycle. you caould refer to the byte based CRC circuit.
