Udi Finkelstein ac10e7d96d Initial implementation of elaboration system tasks 
(IEEE1800-2017 section 20.11)
This PR allows us to use $info/$warning/$error/$fatal **at elaboration time** within a generate block.
This is very useful to stop a synthesis of a parametrized block when an
illegal combination of parameters is chosen.

Enable tests which were disabled due to incorrect treatment of subfields.

Merge pull request #770 from whitequark/opt_expr_cmp 
opt_expr: refactor and improve simplification of comparisons
 2019-01-02 17:34:04 +01:00
whitequark bf8db55ef3 opt_expr: improve simplification of comparisons with large constants. 
The idea behind this simplification is that a N-bit signal X being
compared with an M-bit constant where M>N and the constant has Nth
or higher bit set, it either always succeeds or always fails.

However, the existing implementation only worked with one-hot signals
for some reason. It also printed incorrect messages.

This commit adjusts the simplification to have as much power as
possible, and fixes other bugs.

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
 2018-03-27 14:34:00 +02:00
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)

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.

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.
