No LVDS transmitter channel-to-channel skew data exists for data out port <name>, LVDS transmitter channel <name>, and clock out port <name>


CAUSE: The Timing Analyzer cannot find the LVDS transmitter channel-to-channel skew (TCCS) data for the specified data out port, LVDS transmitter channel, and clock out port in an LVDS circuit. The Timing Analyzer requires this data to calculate TCCS timing information. This error may occur if you have instantiated a megafunction directly in a text file rather than using the MegaWizard Plug-In Manager command (Tools menu).
ACTION: To avoid receiving this message in the future, Altera recommends using the MegaWizard Plug-In Manager to create a megafunction. You can view the results of timing analysis in the Compilation Report.
