| | | | | | | | It seems the issues was that AST_MULTIRANGE is converted into a multirange_dimensions[] array on the AST_MEMORY node directly.
| * $size() seems to work now with or without the optional parameter.Udi Finkelstein2017-09-262-18/+58
| | | | | | | | Multidimensional arrays still don't work. I suspect the problem is that the array is flattened into a 1D array before $size() is evaluated.

| | | | | | | | | | | | | | | | | | | | | | | | This is easily triggered when un-techmapping if the technology-specific cell library isn't loaded. Outputs of technology-specific cells will be seen as inputs, and nets using those outputs will be seen as undriven. Just ignore these cells because they can't be part of a reduce chain anyways.
