Tobias Wölfel 8b8af10f5e Unpacked array declaration using size
Allows fixed-sized array dimension specified by a single number.

This commit is based on the work from PeterCrozier
https://github.com/YosysHQ/yosys/pull/560.
But is split out of the original work.

This PR allows us to use $info/$warning/$error/$fatal **at elaboration time** within a generate block.

illegal combination of parameters is chosen.

Henner Zeller 3aa4484a3c Consistent use of 'override' for virtual methods in derived classes.
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)

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)
