Element bitwidth is best covered as its own special section, as it is quite involved and applies uniformly across-the-board. SV restricts -bitwidth polymorphism to default, default/2, default\*2 and 8-bit -(whilst this seems limiting, the justification is covered in a later -sub-section). +bitwidth polymorphism to default, 8-bit, 16-bit and 32-bit. The effect of setting an element bitwidth is to re-cast each entry in the register table, and for all memory operations involving
