Quartus

LVDS Receiver PLL <name> cds_ena signal de-asserted too early at <time>


CAUSE: During simulation, the cds_ena signal of the specified LVDS Receiver PLL was de-asserted at the specified time in the vector source file before calibration was complete. The cds_ena signal must remain asserted long enough for the Quartus II software to complete calibration.
ACTION: Edit the vector source file so the cds_ena signal stays asserted for at least three consecutive cycles with the valid calibration pattern.
