Detailed Description
Identify a specific subfield (or the whole) of an SSA value using the HW field ID scheme.
fieldID == 0 means the whole value.

Member Data Documentation
◆ bitID
| uint64_t circt::llhd::deseq::ValueField::bitID = 0 |
Optional bit/slice projection within the selected field.
0 means the whole field, otherwise this is lowBit + 1 of a comb.extract applied to the field (and can be chained by addition).

◆ bitWidth
| uint64_t circt::llhd::deseq::ValueField::bitWidth = 0 |
Width (in bits) of the final extracted slice.
0 means no explicit slice width is tracked.

◆ fieldID
| uint64_t circt::llhd::deseq::ValueField::fieldID = 0 |
The HW field ID describing which subfield is referenced.
0 means the whole value.

◆ projection
| Value circt::llhd::deseq::ValueField::projection |
An optional SSA value that already materializes this specific subfield.
For non-projection values, this is identical to value.

◆ value
| Value circt::llhd::deseq::ValueField::value |
The root SSA value being accessed (e.g. the full struct or array).
