one of the 'Timing Optimization Advisor' recommendations for my design is to define a list of clocks as Global Clock in the Assignment editor. how do i do that?

i have tried to enter one of the clocks to the 'Assignment Editor' list in the 'To' column, i selected 'Global Signal' in the 'Assignment Name' column, i selected 'Global Clock' in the 'Value' column...

The To column must be the exact name of your clock. Click the little browse button in the To column cell to open up the Node Finder and search for and select the name of your clock to apply the assignment to.

thanks for the answers but what i get in the report are names that can not be found by the Node Finder.

for example (one of the clocks i get in the report):

'crm_inst|freeclk_pll_inst|pll_inclk50mhz_normal_inst|altera_pll_i|general[0].gpll~FRACTIONAL_PLL|vcoph[0]'

i have found 'crm:crm_inst|pll_inclk50MHz_normal:freeclk_pll_inst|outclk_0' in the Node Finder. configured it as 'Global Signal' in the 'Assignment Name' column and 'Global Clock' in the 'Value' column.

and after the compilation i still get the same line in the report (Node Name - crm_inst|freeclk_pll_inst|pll_inclk50mhz_normal_inst|altera_pll_i|general[0].gpll~FRACTIONAL_PLL|vcoph[0], Global Resource Used - No)
