Negative slack on TimeQuest report

Hi Cris

Thanks for your help.

It´s a hold slack.

My sdc file contains create_clock, derive_pll_clocks, set_clock_uncertainty and derive_clock_uncertainty, as follows:

create_clock -name {CLK} -period 20.000 -waveform { 0.000 10.000 } [get_ports {CLK}]

derive_pll_clocks -use_tan_name

set_clock_uncertainty -rise_from [get_clocks {altpll0:inst1|altpll:altpll_component|altpll_bo32:auto_generated|clk[0]}] -rise_to [get_clocks {altpll0:inst1|altpll:altpll_component|altpll_bo32:auto_generated|clk[0]}] 0.300

derive_clock_uncertainty

I'm following tips from timing advisor (at least as I've understood them :) )

Do you see how can I fix this slack?
