Dear all,
A Correlation Control Block (CCB) has been checked in the CASPER Git
repository in the version ff83a940.
This block is an extension to the existing library block called Gaussian
Random Number Generator (GRNG). CCB can be used along with GRNG block to
get variable correlation between two input noise channels.
The correlation control block uses an uncorrelated noise source whose
coupling to the two input channels is varied to control the correlation.
Currently, there is a facility to select the following values of
correlation through software register - 0% (uncorrelated), 5%, 10%, 20%,
50% and 100% (correlated).
The variable correlation digital noise source design was tested with the
GRNG for a 300MHz BW PoCo with 0.89s integration on ROACH.
For details please refer the following link -

Hope this block is useful for testing CASPER based signal processing
designs. Please let me know your queries, feedback or suggestions in order
to refine the block.
Thanks & Regards,
