Udi Finkelstein 6ddc6a7af4 $size() seems to work now with or without the optional parameter. 
Multidimensional arrays still don't work. I suspect the problem is that the array is flattened into a 1D array before $size() is evaluated.
 2017-09-26 19:18:25 +03:00
Udi Finkelstein 7e391ba904 enable $bits() and $size() functions only when the SystemVerilog flag is enabled for read_verilog 2017-09-26 09:19:56 +03:00
Udi Finkelstein 2dea42e903 Added $bits() for memories as well. 2017-09-26 09:11:25 +03:00
Udi Finkelstein 17f8b41605 $size() now works with memories as well! 2017-09-26 08:36:45 +03:00
Udi Finkelstein 64eb8f29ad Add $size() function. At the moment it works only on expressions, not on memories. 2017-09-26 06:25:42 +03:00
