About the BUFG specification in Intel FPGA.

Hi, In xilinx FPGA, I see the BUFG specification for clock: Does Intel FPGA has the BUFG specification too? Or what's the specification in Intel FPGA equivalent to BUFG, the GCLK or somet...

Hello,
the equivalent term for Intel FPGA is GCLK. You find all details in Arria 10 Handbook, chapter 4 Clock Networks and PLLs in Intel Arria 10 Devices. Don't think i's appropriate to retell the document in this thread. Generally, Arria 10 has 32 GCLKs.

Quartus compilation report tells which resources are utilized for specific signals. Generally, it's rarely necessary or even useful to assign clock resources, e.g. clock control blocks in a design manually.
