Please note that Walter Gallegos start a long discussion with many on the
list, suggesting the use of DCM in the RISC5 Verilog design implemented on
Xilinx FPGAs that gave the block.

You could refer to:

Hope that you find that discussion illuminating on related topics of this
new thread.

Walter also published a VHDL version of Risc5 that I could share with you
in case you're interested. Walter was not responding any email in the last
4 years, that's why I offer you the files.

Best regards,
Prof Pablo Cayuela
