Merge pull request #1759 from zeldin/constant_with_comment_redux 
refixed parsing of constant with comment between size and value
 2020-03-14 13:34:59 +02:00
Marcus Comstedt 5e94bf0291 refixed parsing of constant with comment between size and value 
The three parts of a based constant (size, base, digits) are now three
separate tokens, allowing the linear whitespace (including comments)
between them to be treated as normal inter-token whitespace.

Jeff Wang 16ea4ea61a partial rebase of PeterCrozier's enum work onto current master 
I tried to keep only the enum-related changes, and minimize the diff. (The
original commit also had a lot of work done to get typedefs working, but yosys
has diverged quite a bit since the 2018-03-09 commit, with a new typedef
implementation.) I did not include the import related changes either.

Original commit:
"Initial implementation of enum, typedef, import.  Still a WIP."

Rodrigo Alejandro Melo e9dc2759c4 Fixed some missing "verilog_" in documentation 2019-12-13 10:17:05 -03:00
whitequark e97e33d00d kernel: require \B_SIGNED=0 on $shl, $sshl, $shr, $sshr. 
Before this commit, these cells would accept any \B_SIGNED and in
case of \B_SIGNED=1, would still treat the \B input as unsigned.

Also fix the Verilog frontend to never emit such constructs.

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.

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

Udi Finkelstein 95241c8f4d Yosys can now parse https://github.com/verilog-to-routing/vtr-verilog-to-routing/blob/master/vtr_flow/primitives.v ,

Must use 'read_verilog -defer' due to a parameter not assigned a default value.

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)

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

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)
