Missing system functions #13

Open dtauxe opened 6 years ago

dtauxe commented 6 years ago

I noticed this with $sformatf, but I don't think it's the only one.

Similarly, the functions like $syncnandarray should instead look like $sync$nand$array, at least based on the latest 2017 spec.

Based on the spec, I created the following solution:

to replace the original svSystemFunction. I haven't tested it extensively, so there might be some typos in there somewhere.
