Stefan Biereigel 075a48d3fa implementation for assignments working 2019-05-23 13:57:27 +02:00
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.

whitequark efa278e232 Fix typographical and grammatical errors and inconsistencies. 
The initial list of hits was generated with the codespell command
below, and each hit was evaluated and fixed manually while taking
context into consideration.

    DIRS="kernel/ frontends/ backends/ passes/ techlibs/"
    DIRS="${DIRS} libs/ezsat/ libs/subcircuit"
    codespell $DIRS -S *.o -L upto,iff,thru,synopsys,uint

More hits were found by looking through comments and strings manually.

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)

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.

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)
