Synthesis rework.
...
Synthesis could only handle relatively simple conditional constructs.
This rework aims to make it handle anything the user can throw at it
(or output a sensible message as to why it can't).

Fix minor uninitialized memory access.
2015-10-17 17:06:12 -07:00

Fix for br991 - compiler crashes due to null statements.
...
The reported problem was caused by a null statement in a case statement,
which caused the check for an infinite loop to fail. Further testing
exposed more problems with null statements in loop statements - these
caused crashes earlier in elaboration.

Support negedge flip-flops in synthesis and in vvp.
...
Also extend the support for FF asynchronous set values to vvp and
fix the dff functor in vvp to correctly model asynchronous set/clr
behaviour.
2015-06-13 16:47:57 +01:00

Support declaring queue variables all the way to vvp.

Nothing actually useful happens here, but the declarations
are functional.

d5fb0f4344
Handle some tricky conditions assignments to parts.
...
When for example assigning to foo[<x>] within a contitional, and
doing synthesis, we need to create a NetSubstitute device to manage
the l-value bit selects.
2014-07-14 16:46:58 -07:00

Add some debug convenience functions.
2014-07-14 16:46:57 -07:00
f8dc430fe5
Add synthesis support for casez statements.
...
This generates an EQZ LPM device that carries the case-z-ness to
the code generator.
Also add to the vvp code generator support for the EQZ device so
that the synthesis results can be simulated.
Account for the wildcard devices in the sizer.

nodangle functor accounts for NexusSet links
...
In a design, there may be lingering NexusSet objects, or the
nodangle may itself use NexusSet objects. This creates links,
and this should not confuse the functor.
While we are at it, clean up some handling of events structures.
2014-05-08 15:05:09 -07:00
be0c61051d
Add synthesis of for-loops
...
This required keeping for-loops as actual things through the
netlist form so that the synthesizer can get at and understand
the parts of the for-loop. This may improve vvp code generation
in the future, but for now continue to present to the vvp code
generation the block-while form.

Fix some bugs with packed array dimensions.
...
The netparray_t::slice_dimensions bug was the most insidious and
caused all manner of confusion. Also fix some other packed array
and unpacked array (and mixed) indexing calculations.

Allow some behavioral assignments to unresolved wires.
...
If the l-value is an unresolved wire, then elaboration can allow
the assignment as long as it is to bits that are not otherwise
driven. Handle this in some simple cases.

...
If a signal s driven by multiple non-overlapping NetPartSelect(PV)
objects, then combine them into a single NetConcat object. This
eliminates the need for resolvers in the target.
