Description

A preparator mask is assumed to be hexadecimal, and its size is calculated from the string representation.

I suggest extending the mask format as follows.

// Simple mask in the current format.
0000xxxx

// Symbol _ is ignored.
0000_xxxx

// Prefix '<base> specifies the base: b (B) stands for binary; h (H) stands for hexadecimal.
'b00001111_00001111_00001111_0000xxxx
'h0000_xxxx

// Prefix <width>'<base> specifies the bit width and the base.
32'b00001111_00001111_00001111_0000xxxx
32'h0000_xxxx
