ID:176143 Project contains fast PLL driving <number> SERDES transmitters, but target device can contain only <number> SERDES transmitters per fast PLL

CAUSE: You selected a target device for the current project. However, the Fitter cannot place the project in the target device because the project contains a fast PLL that drives the specified number of SERDES transmitters. The target device can contain only the specified number of SERDES transmitters per fast PLL.

ACTION: Reduce the number of SERDES transmitters per fast PLL in the project or select a larger device.
