whitequark 50fa2516fa hdl.ast: fix some type checks. 2019-04-10 04:33:44 +00:00
whitequark a74cacdc69 hdl.ast: handle a common typo, such as Signal(1, True). 2019-04-03 14:59:01 +00:00
whitequark 81ee2db163 hdl.ast: fix typo. 
Fixes #49.
 2019-03-25 10:50:39 +00:00
whitequark e93bf4bf4b tracer: factor out get_var_name(default=). 2019-03-03 18:21:22 +00:00
whitequark bc5a127fd2 hdl.ast: fix ValueKey for Cat. 2019-01-26 23:25:34 +00:00
whitequark f71e0fffbb hdl.ast: fix shape calculation for *. 
This was carried over from Migen, and is wrong there too.
Counterexample: 1'sd-1 * 4'sd-4 = 4'sd-4 (but should be 5'sd4).
 2019-01-26 00:56:40 +00:00
whitequark 38b3c4af31 hdl.ast: implement shape for modulo operator. 2019-01-19 09:27:56 +00:00
whitequark 5e2b46f727 hdl.ast: add Value.implies. 2019-01-19 08:56:44 +00:00
whitequark b50b47d984 hdl.ast: give Assert and Assume their own src_loc. 
This helps with patterns like `Assert(fsm.ongoing("IDLE"))`, which
would otherwise point into nMigen internals.
 2019-01-19 00:08:51 +00:00
whitequark 66466a8a0e back.rtlil: only emit each AnyConst/AnySeq cell once. 
These are semantically like signals, not like constants.
 2019-01-18 01:34:48 +00:00

William D. Jones 6fdbc3d885 hdl.ast: Add AnyConst and AnySeq value types. 2019-01-15 22:52:45 +00:00
whitequark 011bf2258e hdl: make ClockSignal and ResetSignal usable on LHS. 
Fixes #8.
 2019-01-14 15:38:16 +00:00
whitequark 3083c1d6dd hdl.dsl: accept (but warn on) cases wider than switch test value. 
Fixes #13.
 2019-01-13 08:46:28 +00:00
whitequark a2b04d71d0 hdl.ast: allow slicing [n:n] into n-bit value. 2019-01-02 18:14:57 +00:00
William D. Jones e6517a33c7 hdl.ast: Add Assert and Assign statements. 2019-01-02 11:17:39 +00:00
whitequark ea7e19ed5c hdl.ast: experimentally add Value._as_const. 
Useful for writing e.g. decoders that accept Cat, etc as argument.
 2019-01-01 09:50:39 +00:00
whitequark 39eb2e8fa7 lib.cdc: fix tests to actually run. 2018-12-29 15:02:44 +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 8c4de99c0d hdl.ast: factor out _MappedKeyDict, _MappedKeySet. NFC. 2018-12-17 17:21:29 +00:00
