Udi Finkelstein 6378e2cd46 First draft of Verilog parser support for specify blocks and parameters.
The only functionality of this code at the moment is to accept correct specify syntax and ignore it.
No part of the specify block is added to the AST

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.
