Udi Finkelstein 2b9c75f8e3 This PR should be the base for discussion, do not merge it yet! 
It correctly detects reg/wire mix and incorrect use on blocking,nonblocking assignments within blocks and assign statements.

What it DOES'T do:
Detect registers connected to output ports of instances.

Where it FAILS:
memorty nonblocking assignments causes spurious (I assume??) errors on yosys-generated "_ADDR", "_DATA", "EN" signals.

You can test it with tests/simple/reg_wire_error.v (look inside for the comments to enable/disable specific lines)

Clifford Wolf dbfd8460a9 Allow $size and $bits in verilog mode, actually check test case 2017-09-29 11:56:43 +02:00
Udi Finkelstein e951ac0dfb $size() now works correctly for all cases! 
It seems the issues was that AST_MULTIRANGE is converted into a multirange_dimensions[] array on the AST_MEMORY node directly.
 2017-09-26 20:34:24 +03:00
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.
