Can anyone give me a link to where verilog functions available in Quartus, like the ones mentioned, are documented?
I can't find it anywhere.
Is there any specific function that you would like to use? There are user guides for the application of the Intel Quartus Prime software but not Verilog Standard language manual https://www.intel.com/content/www/us/en/programmable/products/design-software/fpga-design/quartus-pr....
You may refer to the Design Recommendation User Guide that describes best design practices for designing FPGAs with the Intel Quartus Prime software. You may follow the recommended HDL coding styles in the document to ensure that the Intel Quartus Prime Pro Edition software synthesis optimally implements your design in hardware.
There are language templates in the software. Click on Edit > Insert Template
