Speed up the autoname pass by 3x. (#3945) 
* Speed up the autoname pass by 2x. This is accomplished by only constructing IdString objects for plain strings that have a higher score.

* Defer creating IdStrings even further. This increases the speedup to 3x.

Ethan Mahintorabi aa06809d64 rtlil: Speeds up Yosys by 17% 
This PR speeds up by roughly 17% across a wide spectrum of designs
tested at Google. Particularly for the mux generation pass.

Rasmus Munk Larsen e0042bdff7 Speed up TopoSort. The main sorting algorithm implementation in TopoSort::sort_worker is 11-12x faster. Overall, the complete sequence of building the graph and sorting is about 2.5-3x faster. The overall impact in e.g. the replace_const_cells optimization pass is a ~25% speedup. End-to-end impact on our synthesis flow is about 3%. 2023-09-20 15:49:05 -07:00

Jannis Harder 62b4df4989 dft_tag: Implement `$overwrite_tag` and `$original_tag` 
This does not correctly handle an `$overwrite_tag` on a module output,
but since we currently require the user to flatten the design for
cross-module dft, this cannot be observed from within the design, only
by manually inspecting the signals in the design.

Jannis Harder 7a0c37b62d Initial dft_tag implementation 
This is still missing a mode to rewrite $overwrite_tag and $original_tag
by injecting $set_tag and $get_tag in the right places. It's also
missing bit-precise propagation models for shifts and arithmetic and
requires the design to be flattened.

Fix mistaking the read-port and write-port indices for each other when
we are adding the partial transparency emulation to be able to merge two
write ports.
