Udi Finkelstein 80a07652f2 Fixed issue #630 by fixing a minor typo in the previous commit 
(as well as a non critical minor code optimization)

Udi Finkelstein c693f595c5 Merge branch 'master' into pr_reg_wire_error 2018-09-18 01:27:01 +03:00
Udi Finkelstein f6fe73b31f Fixed remaining cases where we check fo wire reg/wire incorrect assignments 
on Yosys-generated assignments.
In this case, offending code was:

module top(input in, output out);
function func;
  input arg;
  func = arg;
endfunction
assign out = func(in);
endmodule

Udi Finkelstein 042b3074f8 Added -no_dump_ptr flag for AST dump options in 'read_verilog' 
This option disables the memory pointer display.
This is useful when diff'ing different dumps because otherwise the node pointers
makes every diff line different when the AST content is the same.

Merge pull request #513 from udif/pr_reg_wire_error 
Add error checking for reg/wire/logic misuse - PR now passes 'make test' (plus a new test)
 2018-08-15 13:35:41 +02:00
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)
 2018-07-20 23:51:06 -07:00
Henner Zeller 3101b9b8c9 Fix remaining log_file_error(); emit dependent file references in new line. 
There are some places that reference dependent file locations ("this function was
called from ..."). These are now in a separate line for ease of jumping to
it with the editor (behaves similarly to compilers that emit dependent
messages).
 2018-07-20 18:52:52 -07:00
Henner Zeller 68b5d0c3b1 Convert more log_error() to log_file_error() where possible. 
Mostly statements that span over multiple lines and haven't been
caught with the previous conversion.
 2018-07-20 09:37:44 -07:00
Henner Zeller b5ea598ef6 Use log_file_warning(), log_file_error() functions. 
Wherever we can report a source-level location.
 2018-07-20 08:19:06 -07:00
Henner Zeller 1a60126a34 Provide source-location logging. 
o Provide log_file_warning() and log_file_error() that prefix the log
  message with <filename>:<lineno>: to be easily picked up by IDEs that
  need to step through errors.
o Simplify some duplicate logging code in kernel/log.cc
o Use the new log functions in genrtlil.

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.
 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
