Quartus

Format of base number <number> is illegal


CAUSE 1: In a Text Design File (.tdf), you did not use a legal radix prefix in the specified base number. A radix prefix must be B for binary, O or Q for octal, or X or H for hexadecimal. Decimal numbers do not use a radix prefix.
ACTION: Change the radix prefix or, for decimal numbers, remove the prefix.
CAUSE 2: In a Text Design File (.tdf), you did not use a series of digits in the specified base number (for example, you used the illegal binary number B""). A base number must have a series of digits, which represent the number, in quotation marks (") after the radix prefix (for example, B"0110X1X10"). Decimal numbers are a series of digits with no radix prefix or quotation marks.
ACTION: Add the digits to the base number.
