Martin Whitaker dbaf2471f2 Fix for br1001 - connect undriven wand/wor to 'bz in tgt-vvp. 2016-03-13 16:38:55 +00:00
Martin Whitaker a5dac08a50 tgt-vlog95: Find the original signal when a port connection is cast. 2016-03-12 23:22:14 +00:00
Martin Whitaker c4b3f256af Don't mislabel signals as ports when casting port connections.
The original signal should retain the port type. Moving it to the cast
signal was confusing the vlog95 and stub targets.

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 94f7504372 vhdlpp: Subprograms are linked to Package instead of generic Scope. 2016-03-07 17:11:53 +01:00

Maciej Suminski 25cd0827ba vhdlpp: Removed ProcessStatement::rewrite_as_always_edge_() & extract_anyedge_().
Processes sensitive to edges are now handled with $ivlh_{rising,falling}_edge().
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.
