Florent Kermarrec de2f1c31d5 sdram: create module.py to define SDRAM modules and use it on de0nano/ppro targets 2015-03-21 16:56:53 +01:00
Florent Kermarrec 6e4b7c6cfd sdram: split sdram_timing in sdram_timing_settings/sdram_controller_settings
req_queue_size, read_time, write_time settings are not sdram_timing settings but sdram controller settings

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
2015-03-21 10:02:10 +01:00
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

Florent Kermarrec 3aee58f484 mibuild/lattice/diamond: add verilog include path (thanks Lattice's FAE since it's not documented) 2015-03-18 18:54:22 +01:00
Florent Kermarrec 236ea0f572 liteeth: use bios ip_address in example designs 2015-03-18 18:18:43 +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)
2015-03-18 15:05:26 +01:00
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.
