In particular, the standard placement flow in nextpnr is a modified [HeAP](https://ieeexplore.ieee.org/document/6339278) followed by simulated annealing for refinement; routing is performed based on [CRoute](https://ieeexplore.ieee.org/document/8735564).

You could perhaps use the limited Synopsis Design Constraint support with `--sdc`. - `create_clock`: supported - `set_false_path`: parsed; requires YosysHQ/nextpnr#1372 - `set_multicycle_path`: requires YosysHQ/nextpnr#1372 The others have no present implementation...

Most nextpnr architectures have an attribute that amounts to "place this flop in I/O". We could probably have one for GateMate too.

No, there physically aren't enough outputs for 4xLUT4.

Micko is on holiday for a few weeks, so questions should be directed to me for now. I'll go take a look at the design and then report my findings.
