Release Notes#

This section lists new features, API changes, and bug fixes. For a complete history, see the Git commit log.

Version 0.39.0#

Add encode_onehot and encode_priority functions to the bits module.

Version 0.38.0#

Lots of new documentation, and improved type hints.

Implemented Empty.__getitem__ for consistency with Scalar, Vector, and Array.

Allow Array slice operator to take string literals as indices.

Relax Bits add and mul operators. Input sizes no longer need to match.

Implement new div and mod operators for basic unsigned division and modulus.

Version 0.37.0#

Add a Module.parameterize class method. For modules that have parameters, this creates a new class for the specific parameter values, which extends from the generic base class.

For example:

>>> class RCA(Module):
...     N: int = 8
...     def build(self):
...         ...

>>> RCA.N
8
>>> RCA_32 = RCA.parameterize(N=32)
>>> RCA_32.N
32

This updates how submodules are instantiated.

Previously:

self.submod(
    name="rca32",
    mod=RCA,
    N=32,
).connect(
    s=s,
    ci=ci,
    a=a,
    b=b,
    co=co,
)

Now this works:

self.submod(
    name="rca32",
    mod=RCA.parameterize(N=32),
).connect(
    s=s,
    ci=ci,
    a=a,
    b=b,
    co=co,
)

Version 0.36.0#

Chose to host documentation on Read The Docs.

Minor improvements to reference documentation.

Added an example Johnson Counter notebook.

Moved clz function from bits module to algorithms.count module.

Added capability to update variables using x.next = <int/bool>.

Previously:

async def drive(valid: Vec[1], data: Vec[8]):
    valid.next = "1b1"
    data.next = "8d42"

Now this works:

async def drive(valid: Vec[1], data: Vec[8]):
    valid.next = 1
    data.next = 42

Version 0.35.0#

Changed VCD VarType used by bit vectors from reg to logic. See PyVCD Changelog version 0.4.1 for details.
