◆ allowNoMatch
| bool circt::synth::CutRewriterOptions::allowNoMatch = false |
Fail if there is a root operation that has no matching pattern.

◆ attachDebugTiming
| bool circt::synth::CutRewriterOptions::attachDebugTiming = false |
Put arrival times to rewritten operations.

◆ maxCutInputSize
| unsigned circt::synth::CutRewriterOptions::maxCutInputSize |
Maximum number of inputs allowed for any cut.
Larger cuts provide more optimization opportunities but increase computational complexity exponentially.

◆ maxCutSizePerRoot
| unsigned circt::synth::CutRewriterOptions::maxCutSizePerRoot |
Maximum number of cuts to maintain per logic node.
The priority cuts algorithm keeps only the most promising cuts to prevent exponential explosion.
