I'm trying to connect datas and a clock from Cyclone 10 GX(output) to another video device(input).
The video device's pins use 3V power, so I need to set 3.0V these datas and a clock.
I set 3.0V by Pin Planner, and processed fitting stage.
But the error message appeared as attached screen shot.
I used 24 data or control signals and 1 clock as 3.0V, I think 3.0V pins aren't in shortage because the bank 2L(it's the only bank can use 3.0V) have 48 pins.
As a test, I removed I/O standard strict of the clock out pin, compilation passed and pin was assigned 1.8V I/O automatically.
This clock out signal is from following route,
LVDS clock input(from external device) > LVDS SERDES(RX) IP inclock pin > rx_coreclock pin > cclock out pin of Cyclone 10 GX
I found that this clock signal type is Periphery (not Global).
Can I change this to a Global clock, or have any simple way to resolve this problem ?

It's seem like you not assigned the pin properly.
May I know your Cyclone 10 GX OPN number?
And can you screenshot your pin planner and send it here?
