all() → Operator¶

Check if all bits are 1.

Return type:: Operator
Returns:: Operator – 1 if all bits are set, 0 otherwise.

any() → Operator¶

Check if any bits are 1.

Return type:: Operator
Returns:: Operator – 1 if any bits are set, 0 otherwise.

as_signed() → Operator¶

Conversion to signed.

Return type:: Operator
Returns:: Operator – This Value reinterpreted as a signed integer.

as_unsigned() → Operator¶

Conversion to unsigned.

Return type:: Operator
Returns:: Operator – This Value reinterpreted as a unsigned integer.

bit_select(offset: Value | int, width: int) → Value¶

Part-select with bit granularity.

Selects a constant width but variable offset part of a Value, such that successive parts overlap by all but 1 bit.

Parameters:

offset (Value | int) – Index of first selected bit.
width (int) – Number of selected bits.

Return type:

Value

Returns:

Part – Selected part of the Value

bool() → Operator¶

Conversion to boolean.

Return type:: Operator
Returns:: Operator – 1 if any bits are set, 0 otherwise.

Assignment.

Parameters:: value (Value) – Value to be assigned.
Return type:: Assign
Returns:: Assign – Assignment statement that can be used in combinatorial or synchronous context.

Implication.

Return type:: Operator
Returns:: Operator – 0 if premise is true and conclusion is not, 1 otherwise.

matches(*patterns: int | str | EnumType) → Value¶

Pattern matching.

Matches against a set of patterns, which may be integers or bit strings, recognizing the same grammar as Case().

Parameters:: patterns (int | str | Enum) – Patterns to match against.
Return type:: Value
Returns:: Value – 1 if any pattern matches the value, 0 otherwise.

rotate_left(amount: int) → Value¶

Rotate left by constant amount.

Parameters:: amount (int) – Amount to rotate by.
Return type:: Value
Returns:: Value – If the amount is positive, the input rotated left. Otherwise, the input rotated right.

rotate_right(amount: int) → Value¶

Rotate right by constant amount.

Parameters:: amount (int) – Amount to rotate by.
Return type:: Value
Returns:: Value – If the amount is positive, the input rotated right. Otherwise, the input rotated right.

shift_left(amount: int) → Value¶

Shift left by constant amount.

Parameters:: amount (int) – Amount to shift by.
Return type:: Value
Returns:: Value – If the amount is positive, the input shifted left. Otherwise, the input shifted right.

shift_right(amount: int) → Value¶

Shift right by constant amount.

Parameters:: amount (int) – Amount to shift by.
Return type:: Value
Returns:: Value – If the amount is positive, the input shifted right. Otherwise, the input shifted left.

word_select(offset: Value | int, width: int) → Value¶

Part-select with word granularity.

Selects a constant width but variable offset part of a Value, such that successive parts do not overlap.

Parameters:

offset (Value | int) – Index of first selected word.
width (int) – Number of selected bits.

Return type:

Value

Returns:

Part – Selected part of the Value

xor() → Operator¶

Compute pairwise exclusive-or of every bit.

Return type:: Operator
Returns:: Operator – 1 if an odd number of bits are set, 0 if an even number of bits are set.
