Another way to actually solve this issue is to not make the clk signal in the ISERDESes CLKB pin inverted. This will invert the clock signal using logic cells, which...

@mithro Yeah, I think that we need to: - [Generate a PAT](https://github.com/settings/tokens) for https://github.com/symbiflow-robot - Add the generated PAT as a secret to symbiflow-arch-defs - Use it as a `gh_access_token`...

> Does this test something in arch-defs that we have a coverage gap on? Actually no, I'll move this into examples (and tool-perf) as you suggested, as this design does...

I am unsure as well here actually. I don't think there is a way to specify the frontend for each single file in the list of input files. Another solution...

Hi @the-centry, can you please provide an example of the tile that causes the behaviour you are seeing?

@litghost Yep, I have thought that maybe, we exceed in the production of the `tiles.json5` temporary files. Meaning that we could use an ROI to shrink the data produced, being...

@litghost Right, I'll start to profile run-time in a more detailed way to get where exactly is the bottleneck of the process.

@litghost I think I have identified what the problem is and where is the bottleneck. By disabling the pip loop that extracts all pips related to a tile, run-time dropped...

@litghost That was the right call, run-time is now `~13 minutes` for the tiles job ``` Tiles Job start time: 2020-01-28 17:47:59.772677 Tiles Job end time 2020-01-28 18:00:31.769572 ```

Hi @benglines, thanks for this PR. There is now a conflict in the README after merging https://github.com/SymbiFlow/prjxray/pull/1678, and this would require a rebase.
