Errors when Editing Transmitters v7.2 or Earlier in v8.0

Description

If you edit a v7.2 or earlier 64 or 128-bit transmitter MegaCore variation in the v8.0 or later MegaWizard Plug-In, the PLL input frequency is set to 1 MHz, which is incorrect.

This issue affects 64- and 128-bit transmitters.

There is no design impact.

Resolution

To work around the issue, follow these steps:

1. Click in the LVDS Data Rate dialog box.
2. Press Enter.

The PLL input frequency parameter resets to the correct value-data rate divided by deserialization factor.

This issue will never be fixed.
