          Yes there are predefined masks for some standards in Hyperlynx Like PCIe and USB.

          you can check it by selecting Eye -Diagram --> Configure Eye mask in drop down you can see the predefined standards.

          For DDR3 probably we go for Vil,Voh, values for defining eye mask.

            Thanks for your reply

                                I know how to create eye mask.  I found in some standards the high low values are available with  UI percentage .because eye is having timing parameter also % of UI for reaching the voh and vol , how to create it for LVPECL  SIGNAL STANDARD, i mean the values of UI to be put and vh and vl values ,or can i use any of the pre defined eye mask for simulating the LVPECL signal
