Martin Whitaker c1c4d8c863 Fix bitmask merging in synthesis. 
A conditional clause that doesn't drive any bits of a particular nexus
should not affect the bitmask generated for that nexus. The completely
undriven case is handled by the enable signal.

Vhdlpp fixes
 2016-03-07 09:05:36 -08:00
Maciej Suminski de775975e8 ivl: Fixed slice base calculation 
when range is rising (e.g. logic [0:3] arr) or when it
starts with a non-zero integer (e.g. logic [4:1] arr).
 2016-03-07 17:11:53 +01:00
Maciej Suminski 770906ba0d vhdlpp: Write binary constants as a string of bits. 2016-03-07 17:11:53 +01:00

Maciej Suminski 25cd0827ba vhdlpp: Removed ProcessStatement::rewrite_as_always_edge_() & extract_anyedge_().

 2016-03-07 11:38:11 +01:00
Maciej Suminski 7cbb275ffe vhdlpp: Handle limited-length strings in reports. 
Currently limited-length strings (e.g. string(1 to 4)) are
emulated using 2D array of bits (e.g. bit [1:4][7:0]).
Because of that, ivl treats them as standard vectors and
$display() does not show them as strings. Now, they are
wrapped with $sformatf("%s", ..) to fix it.
