Hi everyone!
I'm trying to execute NIOS's code from User Flash Memory located inside MAX10.
My eval board is
https://www.altera.com/products/boards_and_kits/dev-kits/altera/kit-max-10-evaluation.html.
Onboard clock 50 MHz I connect to NIOS clk input.
In top-level .sdc file I create this clock by string: create_clock -name {clk} -period 20.000 -waveform { 0.000 10.000 } [get_ports { clk }]
But after Quartus processing, Timquest find negative hold slacks for all drdout[] nodes of UFM block.
I see that Timequest analyze path from each drdout[] node to itself!
I don't understand what is the sense of it ?
Moreover, after deleting string "create_clock -name {clk} -period 20.000 -waveform { 0.000 10.000 } [get_ports { clk }]" from top-level .sdc file everything is OK, i.e. Timequest doesn't find negative slacks.
But I think, it's wrong idea to delete "create_clock..." from sdc file.
Who can help to define problem ?
