Honored ContributorInternal Oscillator for MAX10 device
Hello. I am trying to use internal oscillator in MAX10 FPGA. It works but I am getting 83 mhz instead of desired 55 mhz. Already confusing the frequency setting in IP altera_int_osc. It says C...

Honored Contributor --- Quote Start --- That is not implicit. The datasheet indicates explicitly that the internal oscillator can range from 55MHz to 116Mhz, and nominally is 82MHz. There is no way for you to change it in your physical device; if you could the datasheet would indicate how to do so. It does not. You can change it in simulation to reflect the min/max value range, so you can check your design. But that is for simulation only. --- Quote End --- The docs above do not describe any IP options. I could get it only at implementation stage. Is not right, that's why I say that it is implicit description in the specs. Not only me who was reading their specs. With the same success they could write the range from 0 Hz up to ANY MHz. So .... nice trick. Anyway I have to use external oscillator instead of this nightmare. Thanks for your reply as it clarified a lot of things
