Robert Jordens 860b72c8b6 pipistrello: rename sdram->ddram 2015-03-19 18:48:22 +01:00
Sebastien Bourdeauducq 7fa1cd72a8 fhdl/verilog: fix dummy signal initial event 2015-03-19 00:24:30 +01:00
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 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.

Robert Jordens 3e84c66ba9 vivado: permit resources without pins
This is required if the LOC is done by another, external constraints set,
as in the case of the Zynq Processing System Instance.
