Martin Whitaker ca02b3ae53 vlog95 target enhanced to support constant input to LPM_SUBSTITUTE. 2016-02-27 21:13:57 +00:00
Martin Whitaker f84f0535cf Renamed synthsplit to exposenodes. 
This was needed to avoid automatically setting the synth flag in the
compiler.

Martin Whitaker a33255f0e0 Add support for LPM_SUBSTITUTE and wider LPM_MUX objects in vlog95 target. 2016-02-27 18:08:56 +00:00
Martin Whitaker 9d5f4ad048 Add new synthsplit functor. 
This provides support for handling synthesis constructs in the vlog95
target.

Martin Whitaker a0bee0a76f Add support for real valued compressed assignment statements in tgt-vvp. 2016-02-23 22:02:03 +00:00
Martin Whitaker a85c64d347 Revert "Add support for real valued compressed assignment statements in tgt-vvp." 
This reverts commit 3fede95f5e.
 2016-02-23 21:49:49 +00:00
Martin Whitaker 3fede95f5e Add support for real valued compressed assignment statements in tgt-vvp. 2016-02-23 20:58:30 +00:00
Martin Whitaker a7066e3686 Fix expression/operator type for compressed assignment/shift. 2016-02-23 20:57:30 +00:00
Martin Whitaker 0199ad129d Fix expression type for compressed assignment statements. 
A compressed assignment statement should give exactly the same
result as the equivalent uncompressed statement. This means
that the type (signed/unsigned) of the LHS affects the type of
the RHS expression (unlike in normal assignments). We need to
take care that bit/part selects and concatenations are correctly
identified as unsigned values, even in the cases where they
reduce to a single whole signal.

Martin Whitaker 241b6723e5 Fix lval extension for compressed assignment in constant function. 
The type of extension (zero/sign) is determined by the expression
type, not the operand type, so we need to cast to the expression
type before extending the value.
 2016-02-23 16:46:26 +00:00
Martin Whitaker b77d758f19 Fix compressed assignments to concatenations. 
When loading a lval concatenation, tgt-vvp was loading the elements
in the wrong order for the %concat instruction.
 2016-02-23 16:44:03 +00:00
Martin Whitaker 1a78784205 Removed some dead code. 2016-02-23 11:58:27 +00:00
Martin Whitaker f9f51db7ba Extended constant function assignment operator support to real values. 
Also output a "sorry" message if the LHS is a concatenation.
 2016-02-22 23:31:35 +00:00
Martin Whitaker 74b8c04b91 Add support for SystemVerilog assignment operators in constant functions. 2016-02-22 22:22:22 +00:00

Peter Jakobsen cbced021a1 Add missing symbols for dlltool to export 2016-02-22 09:49:06 -08:00
Martin Whitaker f3cf7ca546 Updated comments for synthesis. 2016-02-21 22:39:52 +00:00
Martin Whitaker f29935d8dd Enhanced support for asynchronous set/reset in synthesis. 
Added the ability to coalesce set/reset values to different parts
of the same vector. Also added a check that all bits of the vector
are assigned a value.
Enabled coalescence of asynchronous set/reset part-vectors
 2016-02-21 21:46:36 +00:00
Martin Whitaker 3fc0204b99 Fix cleanup of NetEvWait class. 
The destructor needs to delete the stored NetEvent objects. Failure
to do this was causing a compiler crash after synthesis if the
nodangle functor was disabled.
 2016-02-21 21:22:35 +00:00
Martin Whitaker 5286fb858d 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).

Martin Whitaker 46105e0c5a Delayed output of vvp dff to end of current time slot. 
Flip-flops are generally modelled in behavioural code using non-blocking
assignments. This change makes the synthesised code behave the same as
the behavioural code. It's a more realistic model of a real flip-flop
too, which will always have some clock-to-output delay.

Maciej Suminski 71084109f6 Save the time format suffix string. 
In case of a vhdlpp-specific () call, the timeformat suffix string was overridden,
therefore it has to be restored to the previous value after the call.
