net uselowskewlines

Hi,

As i don't have enough BUFG, i'm using simple IBUF to my clock signal. Can i use USELOWSKEWLINES constrint along with MAXSKEW constraint for the same clock signal?

eg.
NET "p1_sck_sig" USELOWSKEWLINES;
NET "p1_sck_sig" MAXSKEW = 1 ns;

Regards,
kaka

Yeah I have done it and it worked, yet it depends on the fanout mainly, if you have a clock feeding 100 logic cell I doubt that you can get less than 1 ns skew,
yet you may give it a try.
