You can use decimal, binary, octal, and hexadecimal numbers in any combination in AHDL. The syntax for each radix (numbering system) is shown below.
| Radix: | Values: | |
| Decimal | <series of digits 0 to 9>
|
|
| Binary |
B"<series of 0's, 1's, X's>"(where X = "don't care")
|
|
| Octal |
O"<series of digits 0 to 7>" orQ"<series of digits 0 to 7>"
|
|
| Hexadecimal |
X"<series from 0 to 9, A to F>" orH"<series from 0 to 9, A to F>"
|
The following examples show valid AHDL numbers:
B"0110X1X10" Q"4671223" H"123AECF"
The following rules apply to AHDL numbers:
The Compiler always interprets numbers in Boolean Expressions as groups of binary digits; numbers in group ranges are interpreted as decimal values.
Numbers cannot be assigned to single nodes in Boolean equations. Use
VCC and GND instead.
