Extract bit range

Extracts a contiguous bit range from an unsigned 32-bit word.

Behavior

y = (word >> first_bit) AND ((1 << count) − 1). The worked example connects this operation to signals in Lemonergy Studio.

Original Lemonergy interface view. Lines identify ports; they are not a completed simulation circuit.

Ports and observed outputs
Name	Direction	Unit	Meaning
`in0`	input	1	Word; u32 scalar.
`out0`	output	1	Result; u32 scalar.

Defaults are initial model values. Select values for your own model and operating conditions.

Configuration fields
Parameter	Unit	Default	Meaning and limits
First bit `params[0]`	1	2	Zero-based, least significant first.
Bit count `params[1]`	1	3	Configured finite numerical parameter.

Word = 44. Result at 0 s = 3.

Numerical checks for the bundled synthetic example
Output	Time (s)	Expected value	Unit	Absolute tolerance
Result `out0`	0	`3`	1	1e-08

Extracts a contiguous bit range from an unsigned 32-bit word.

Extract bit range: y = (word >> first_bit) AND ((1 << count) − 1). The worked example connects this operation to signals in Lemonergy Studio.
- Use the block reference for settings and connections.
- Implementation tested locally; public release pending.

Shapes and element types are explicit. Values must be finite; automatic reshaping and unit conversion are not performed.

This software operation and its numerical conventions are defined by the public contract and worked example; no external research result is claimed.

This reference follows the public interface and locally verified numerical checks for an upcoming release.
