ID:10668 Verilog HDL or VHDL error at <location>: the message ID <id> specified in the HDL source is invalid.

CAUSE: In a Verilog Design File (.v), you specified a message_on or message_off directive, and followed that with an integer intended to be a message ID. However, since the integer is not a valid message ID, it is very likely there was a typo when specifying the message ID.

ACTION: Check the text of the message you want to turn on or turn off; the message ID is in the message text.
