Delays in assignments

[jotego]

There are many #1 delays in the assignments. I think that number is arbitrary, and it doesn't help with synthesis nor simulation. I have used this core removing those statements here. If these assignments were removed in the original repository, I could just point to it (using git submodule) rather than copying the files.

Could you remove the assignments? If you prefer it, I could make a pull request for this.

I replaced the assignments with a define which defaults to null, which should fit the bill.
