Decomposition after router missing #492

Open jvansomeren opened 1 year ago

jvansomeren commented 1 year ago

The optional decomposition to primitives after the router has been omitted during the merge. This leads to changes in the golden output files of the tests such as:

The only change is that there are 17 non-decomposed swaps now versus decomposed ones before. That is about 3 cycles for each swap more cycles on a duration of a swap of 10 cycles. That could explain it. Because a non-decomposed swap reserves all resources (and there are several) for the full 10 cycles, while a decomposed swap only does that for the durations of the individual primitives.

Adding a decomposition pass after the router would prevent this.
