Merge pull request #610 from udif/udif_specify_round2 
More specify/endspecify fixes
 2018-08-23 14:43:25 +02:00
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.
 2018-08-23 15:26:02 +03:00
Udi Finkelstein fbfc677df3 Fixed all known specify/endspecify issues, without breaking 'make test'. 
Some the of parser fixes may look strange but they were needed to avoid shift/reduce conflicts,
due to the explicit parentheses in path_delay_value, and the mintypmax values without parentheses
 2018-08-20 17:27:45 +03:00
Udi Finkelstein 95241c8f4d Yosys can now parse https://github.com/verilog-to-routing/vtr-verilog-to-routing/blob/master/vtr_flow/primitives.v , 
(specify block ignored).
Must use 'read_verilog -defer' due to a parameter not assigned a default value.
 2018-08-20 00:08:08 +03:00
Udi Finkelstein 28cfc75a90 A few minor enhancements to specify block parsing. 
Just remember specify blocks are parsed but ignored.

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)

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.

Henner Zeller b5ea598ef6 Use log_file_warning(), log_file_error() functions.

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)
