Maximum Operating frequency: NIOS2 system on Max10

To optimize the Qsys interconnect, you can refer to this UG https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/qts-qps-5v1.pdf?wapkw=quartus+handbook+18.1+standard, 8-12 Inserting Pipeline Stages to Increase System Frequency & 8-13 Using Bridges. The first method can be easily applied, just changing one setting, and should give some improved Fmax result but it incurs some latency in the transfer.
