AC800M Group Data Register
Does such an element exist in an AC800M library?
It depends on what was the original purpose of using REG-G. Usually REG-G serves as data entry for FUNG-1V function. In Ac800m you can use group data type of 16 or more Reals coldretain. Group Data type shall be compatible with PiecewiseLinear or Fung-1v data inputs.
REG-G migration is implemented in ampl2m conversion tool.
I hope it helps
