Robert Jordens 14b1da4018 test_actor: add unittests for SimActor
* also implicitly tests for the access of signals during simulation that are
not referenced in any statements

* before, if the busy signal is never used, it is stripped
  and could not be accessed in simulation

Robert Jordens 5f045b7649 sim: keep track of unreferenced items
* items that are never referenced in any statements do not end up in the
namespace or in the verilog

* this memorizes items if they can not be found in the namespace and keeps
track of their values

Sebastien Bourdeauducq 7fa1cd72a8 fhdl/verilog: fix dummy signal initial event 2015-03-19 00:24:30 +01:00
Florent Kermarrec 5a9afee234 fhdl/specials/memory: use $readmemh to initialize memories 2015-03-18 15:27:01 +01:00
Florent Kermarrec c0fb0ef600 fhdl/verilog: change the way we initialize reg: reg name = init_value;
This allows simplifications (init in _printsync and _printinit no longer needed)

Florent Kermarrec ea9c1b8e69 fhdl/verilog: revert "fhdl/verilog: add simulation parameter to avoid simulation tricks in synthetizable code"
This probably breaks simulation with Icarus Verilog (and others simulators?)

Florent Kermarrec 2fc2f8a6c0 migen/genlib/io: use 0 instead of Signal() for default rst value (immutable thanks sb) 2015-03-18 14:41:43 +01:00
Sebastien Bourdeauducq bdc47b205a Revert "fhdl/verilog: do not use initial begin in _printinit (not accepted by all synthesis tools ex: Synplify Pro does not accept it)"
This breaks simulations, and we will try to use the "reg name = value" syntax instead.

This reverts commit e946f6e453.

Florent Kermarrec 9adf3f02f2 fhdl/verilog: add simulation parameter to avoid simulation tricks in synthetizable code
it's generally better to have identical code between simulations and synthesis, but here tricks inserted for simulation are clearly expected to be simplified by synthesis tools, so it's better not inserting them.

Florent Kermarrec 33c3a927c2 actorlib/structuring: add Pipeline
Pipeline enables easy cascading of dataflow modules.
DataFlowGraph can eventually use it to implement the
add_pipeline method to avoid duplicating things.

Florent Kermarrec 8db549a23d actorlib/structuring: add Converter
Converter enables easy conversions of data width on dataflows.
It handles the 3 possibles cases:
- downconverter
- upconverter
- direct connection when data width are identical.
