whitequark cf79738744 cli: new module, for basic design generaton/simulation. 2018-12-23 00:06:58 +00:00
whitequark 621dddebfd hdl.xfrm: avoid cycles in union-find graph in LHSGroupAnalyzer. 2018-12-22 22:19:14 +00:00
whitequark 3448953f61 compat.genlib.fsm: fix naming for non-Signal LHS. 2018-12-22 22:00:58 +00:00
whitequark 68dae9f50e hdl.ir: flatten hierarchy based on memory accesses, too. 2018-12-22 21:43:46 +00:00
whitequark fd89d2fc9d hdl.ir: factor out _merge_subfragment. NFC. 2018-12-22 19:04:49 +00:00
whitequark 59c7540aeb back.rtlil: split processes as finely as possible.
This makes simulation work correctly (by introducing delta cycles,
and therefore, making the overall Verilog simulation deterministic)
at the price of pessimizing mux trees generated by Yosys and Synplify
frontends, sometimes severely.
2018-12-22 10:03:16 +00:00
whitequark d29929912f back.rtlil: remove useless condition. NFC. 2018-12-22 07:24:15 +00:00
whitequark ae0cb48fbb hdl.xfrm: implement LHSGroupAnalyzer. 2018-12-22 06:58:24 +00:00
whitequark 98a9744be4 hdl.xfrm: Abstract*Transformer→*Visitor 2018-12-22 06:03:39 +00:00
whitequark 37b81309d3 back.rtlil: always initialize the entire memory.
This avoids reading 'x from the memory in simulation. In general,
FPGA memories can only be initialized in block granularity, and
zero-initializing is cheap, so this is not a significant issue with
resource consumption.
2018-12-22 05:27:42 +00:00
whitequark 99b778158d compat: use nicer names for next_value/next_value_ce signals. 2018-12-22 02:05:49 +00:00

whitequark 6ee80408bb back.verilog: do not rename internal signals.
_0_ is not really any better than \$13, and the latter at least has
continuity between nMigen, RTLIL and Verilog.
2018-12-22 00:53:40 +00:00

whitequark 6672ab2e3f back.rtlil: explicitly pad constants with zeroes.
I'm not sure what exactly RTLIL does when a constant isn't as long
as its bit width, and there's no reason to keep the ambiguity.

whitequark 2be76fda3c hdl.xfrm: separate AST traversal from AST identity mapping.
This is useful because backends don't generally want or need AST

node, it results in confusing type errors.
