whitequark	c337246fc5	hdl.ir: when adding sync domain to a design, also add it to ports. Otherwise we end up in a situation where the examples don't have clk and rst as ports, which is not nice. Fixes #67.	2019-05-15 06:44:50 +00:00
whitequark	39bc59c924	hdl.ir: during port propagation, defs should take priority over uses.	2019-05-13 15:34:13 +00:00
whitequark	958cb18b88	hdl.ir: only pull explicitly specified ports to toplevel, if any. Fixes #30.	2019-05-12 05:21:23 +00:00
whitequark	585514e6ed	hdl.ir: rework named port handling for Instances. The main purpose of this rework is cleanup, to avoid specifying the direction of input ports in an implicit, ad-hoc way using the named ports and ports dictionaries. While working on this I realized that output ports can be connected to anything that is valid on LHS, so this is now supported too.	2019-04-22 07:46:47 +00:00
whitequark	8ee6bd80ff	hdl.ir: raise a more descriptive error on non-elaboratable object.	2019-02-14 20:52:42 +00:00
whitequark	4948162f33	hdl.ir: rename .get_fragment() to .elaborate(). Closes #9.	2019-01-26 02:31:12 +00:00
whitequark	b534e92dd5	hdl.ir: allow explicitly requesting flattening.	2019-01-14 17:04:23 +00:00
whitequark	040811c2e5	hdl.ir: add an API for retrieving generated values, like FSM signal. This is useful for tests.	2018-12-26 12:35:35 +00:00
whitequark	68dae9f50e	hdl.ir: flatten hierarchy based on memory accesses, too.	2018-12-22 21:43:46 +00:00
whitequark	f6772759c8	hdl.ir: fix port propagation between siblings, in the other direction.	2018-12-22 00:31:31 +00:00
whitequark	913339c04a	hdl.ir: fix port propagation between siblings.	2018-12-21 23:53:18 +00:00
whitequark	b0bd7bfaca	hdl.ir: correctly handle named output and inout ports.	2018-12-21 04:03:03 +00:00
whitequark	f7fec804ec	ir: allow non-Signals in Instance ports.	2018-12-20 23:40:40 +00:00
whitequark	c7f9386eab	fhdl.ir: add black-box fragments, fragment parameters, and Instance.	2018-12-17 22:55:39 +00:00
whitequark	8d1639a5a8	hdl, back: add and use SignalSet/SignalDict.	2018-12-17 17:21:29 +00:00
whitequark	c6e7a93717	hdl: appropriately rename tests. NFC.	2018-12-15 16:13:53 +00:00
