10 years agoThank you very much for your response,
i created a sdc file with those parameters: create_clock -name {CLOCK50MHz} -period 20.000 [get_ports { clk_clk }] derive_clock_uncertainty derive_pll_clocks The TimeQuest report says, that fmax could be 117 MHz on the PLL Clock and 250MHz on the input clock *the logic only consists of the nios system there is nothing else in the design
