Numbering conventions

The following convention of stating constant numbers is used:

●

[<size in bits>]’<base><number>

where:

●

<size in bits>: (optional) width of bits field associated to <number>

●

<base>: “b” for binary, ‘h” for hexadecimal, “o” for octal, “d” for decimal

●

<number>: value of constant number, according to <base>

Examples:

‘d19

unsized decimal value

8’h2C

8-bit wide hexadecimal value of 0x2C, corresponding to b00101100

8’b011001

8-bit wide binary value of b00011001

32’hFFFF

32-bit wide hexa decimal value of 0xFFFF, corresponding to

b00000000000000001111111111111111
