to create a file.xcf I made a copy of the file.ucf and changed the extension. this is correct?
my file.xcf has the following syntax:
#Created by Constraints Editor (xc5vlx30-ff324-3) - 2011/12/15NET "clk" TNM_NET = clk;TIMESPEC TS_clk = PERIOD "clk" 1 ns HIGH 50%;
change the options in the summary and I want to see the resources used by changing the time constraint
