Description:
The user encounters a WARNING message shown below whenever they utilize a PLL IP.
"Generated_clock: not connect to any master clock pin."
Solution:
The warning implies that the timing engine is indicating that there is no clock at the source pin. The user needs to define a clock on the port that drives the reference pin of the PLL.
At Radiant 2023.2 or later, the message will be changed from "Generated_clock: not connected to any master clock pin." to "Generated_clock: clock not found on source pin.".
