Add support to handle attributes at module instantiation sites.
 2017-03-16 09:38:04 -07:00
Vamsi Vytla cfd3b893be Add support to handle attributes at module instantiation sites. 
(* my_fancy_attribute *)
foobar1 foobar (clk(clk), rst(rst) ...);

  - Modifies PGModule to hold the attribute map (can be verified with pform_dump)
  - pform_make_modgate(s) bind the attributes from the parser to the above map
  - The attributes from PGModule are inserted into the NetScope of that module
    PGModule::elaborate_scope_mod_instances_
  - Currently these attributes automatically make it into netlist
  - These attributes are accessible via ivl_scope_attr_cnt and ivl_scope_attr_val
    from ivl_target.h

Martin Whitaker edb922f613 Use correct format strings for PLI_UINT64 in printf/scanf functions. 2016-10-14 20:35:36 +01:00
Martin Whitaker 7ddc514518 Allow library files to be specified on the iverilog command line. 
This was already supported in command files, using the '-v' flag.
'-v' is already in use on the command line, so use '-l' instead,
and make that an alias for '-v' in command files.

Martin Whitaker 0fdf29e099 Fix for GitHub issue #117 - delays in VPI simulation time callbacks. 
Change cbReadWriteSynch and cbReadOnlySynch to interpret the passed
time value as a relative delay, not an absolute time. This matches
the behaviour of other simulators.

Cary R c706c5dd90 The array properties can be available in a constant context 
For most arrays the various properties are available as constant
values and can be evaluated in the compiler.

Martin Whitaker 3c9b39846c Use gn_system_verilog() where appropriate. 
Replace explicit comparisons against generation_flag with calls to
the gn_system_verilog helper function, both for code clarity and
to fix a couple of bugs. Also simplify the implementation of the
function, as we already rely on the generation_flag enumeration
being an ordered list.

Maciej Suminski 8ba3d62071 vhdlpp: Better resize() implementation. 
Previous version did not work well with signed expressions or expressions that
were temporarily resized (e.g. a + 32'd42, where a is a[7:0]).
 2016-09-01 12:08:44 +02:00
Maciej Suminski bab39dae19 vhdlpp: Some of the standard library functions are imported only on request 
Previously they have been always enabled, now it is required to put a
'use' directive.

Maciej Suminski 07543315cf vhdlpp: Stricter array type matching 
Arrays type match if they have a common parent, instead of the
element type. Now (un)signed & std_logic_vector types do not match,
as it should be in VHDL.
