Merge pull request #679 from udif/pr_syntax_error
More meaningful SystemVerilog/Verilog parser error messages
2018-10-25 13:18:59 +02:00
Udi Finkelstein 536ae16c3a Rename the generic "Syntax error" message from the Verilog/SystemVerilog parser into unique,
meaningful info on the error.
Also add 13 compilation examples that triggers each of these messages.

Ruben Undheim c50afc4246 Documentation improvements etc.
- Mention new feature in the SystemVerilog section in the README file
- Commented changes much better
- Rename a few signals to make it clearer
- Prevent warning for unused signals in an easier way
- Add myself as copyright holder to 2 files
- Fix one potential memory leak (delete 'wire' if not in modport)

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

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.

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 ,
(specify block ignored).
Must use 'read_verilog -defer' due to a parameter not assigned a default value.
