signed: false needs a bitWidth to render a two's-complement pattern; defaulting to 32

What happened

signed: false renders a negative number as the bit pattern it would have in a fixed-width register, and without a width there is nothing to complement against. Rather than silently re-signing the value, the formatter picks the commonest width - 32 bits - so a negative number renders as a 32-bit pattern.

The fix

State the bitWidth you mean.

The smallest fix

radix: { radix: 16, signed: false, bitWidth: 16 }
