whitequark 0899ff366b compat.fhdl.bitcontainer: fix value_bits_sign(). 
This function was broken in commit 659b0e81; some downstream code
expects bits_sign to be e.g. indexable.
 2020-07-21 02:53:29 +00:00
whitequark 8dd28fecc6 compat.fhdl.specials: fix handling of tristate (i=None) pins. 
Fixes #406.
 2020-07-02 22:22:44 +00:00
Jacob Lifshay 995f3a147b Add support for using non-compat Elaboratable instances with compat.fhdl.verilog.convert and compat.run_simulation 
Fixes #344

whitequark 9fb4a4f09e _unused: extract must-use logic from hdl.ir. 2020-02-01 01:35:05 +00:00
whitequark e18385b613 Remove everything deprecated in nmigen 0.1. 
Closes #275.
 2020-01-12 13:59:26 +00:00
whitequark 9fba5ccb51 compat.fhdl.specials: fix argument parsing compatibility. 2019-10-17 07:54:36 +00:00
whitequark 2f9dab361f {,_}tools→{,_}utils 
In context of nMigen, "tools" means "parts of toolchain", so it is
confusing to have a completely unrelated module also called "tools".
 2019-10-13 18:53:38 +00:00
whitequark 13650acbbc compat.fhdl.decorators: improve backwards compatibility. 2019-10-13 01:38:09 +00:00
whitequark d2c4c7c060 compat.fhdl.bitcontainer: update Value.wrap call. 2019-10-13 01:37:11 +00:00
whitequark dbddddff17 compat.fhdl.decorators: add migration warnings. 2019-10-12 22:45:03 +00:00
whitequark a7e3b80409 hdl.ast: rename Slice.end back to Slice.stop. 
It used to be called .stop in oMigen, and it's also called .stop in
Python range and slice objects, so keep that.
 2019-10-12 22:40:48 +00:00
whitequark 77118fb9c9 compat.fhdl.structure: remove SPECIAL_* constants. 
They cannot be used with nMigen designs since nMigen does not have
specials.
 2019-10-12 22:40:48 +00:00
whitequark da48c05bdf _tools: extract most utility methods to a private package. 
We don't want to guarantee backwards compatibility for most of them.
 2019-10-12 22:40:48 +00:00
whitequark d72d4a55fd hdl.ast: Value.{wrap→cast} 
Preparation for #225.
 2019-10-11 10:49:34 +00:00
whitequark a2241fcfdb back.{rtlil,verilog}: split convert_fragment() off convert(). 
Because Fragment.prepare is not (currently) idempotent, it is useful
to be able to avoid calling it when converting. Even if it is made
idempotent, it can be slow on large designs, so it is advantageous
regardless of that.
 2019-08-19 19:49:51 +00:00
whitequark 84f2c3df2b compat.fhdl.decorators: avoid using deprecated NativeCEInserter. 2019-08-18 16:27:11 +00:00
whitequark e6b1e3de1a compat.fhdl.decorators: port from oMigen. 2019-08-08 08:09:28 +00:00
whitequark 5c626e33bf compat.fhdl.module: fix finalization of transformed compat submodules. 
Before this commit, the TransformedElaboratable of a CompatModule
would be ignored, and .get_fragment() would be used to retrieve
the CompatModule within.

After this commit, the finalization process is reworked to match
oMigen's finalization closely, and all submodules, native and compat,
are added in the same way that preserves applied transforms.
 2019-08-08 07:45:34 +00:00
whitequark 0fe05188e8 compat.fhdl.specials: track changes in build.plat. 2019-08-03 22:52:34 +00:00
whitequark fdb0c5a6bc hdl.ir: call back from Fragment.prepare if a clock domain is missing. 
See #57.
 2019-08-03 14:54:20 +00:00
whitequark 668ff40a75 compat.fhdl.specials: mark CompatMemory as Elaboratable. 
This suppresses a warning that is not useful in the compat context.
 2019-07-03 13:28:57 +00:00
whitequark eeb6aca93d compat.fhdl.specials: use "sync" as default domain, not "sys". 
In compat.fhdl.module, we already default to "sync" as the default
clocked domain. Using "sys" in memories only would be inconsistent
and result in more bugs.
 2019-07-03 13:25:12 +00:00
whitequark c98b8f7c07 compat.fhdl.specials: fix Memory.get_port() after 94e8f479. 
This also makes sure the native ports are instantiated for correct
clock domain.
 2019-07-03 13:24:00 +00:00
whitequark 9eb81609d6 compat.fhdl.structure: fix If/Elif/Else after 32446831. 2019-07-03 13:19:15 +00:00
whitequark 32446831b4 hdl.{ast,dsl}, back.{pysim,rtlil}: allow multiple case values. 
This means that instead of:

    with m.Case(0b00):
        <body>
    with m.Case(0b01):
        <body>

it is legal to write:

    with m.Case(0b00, 0b01):
        <body>

with no change in semantics, and slightly nicer RTLIL or Verilog
output.

Fixes #103.
