Adding 128 bits option for wires and registers

[PteronuraBrasiliensis]

Hi, i am in the process of designing a vector unit for a custom CPU. This unit needs some 128 bits registers but only 64 bits ones are available. Currently, i am able to work around this problem by using two 64 bits wires and two 64 bits registers, but the further i get into this project, the messier it gets. Would it be possible to add 128 bits options for wires and registers ?

That is not that easy, as it requires changes in many places. See, e.g., the PRs which were required for lifting the limitation from 32 bits to 64 bits. PRs in this direction are welcome. However, care must be taken to not negatively impact the overall simulation performance when such large signal buses are not used in a design.
