The fabs are using the EDA companies the same way PC manufacturers used Microsoft in the 1990s. There is only really one company for each particular piece of the EDA toolchain -- Cadence and Synopsys don't really compete directly now that they've run everybody else out of business (or bought them up). "Using" here is in the symbiotic sense.
I think Siemens deserves to be on the list but your main point remains. They all really excel at one step or another in the EDA chain. Even they do compete generally across the all broad scopes it sometimes feels like it is not a serious effort. Sometime I wonder which is cause and which is effect, is the reason some fabs simply don't provide PDK support for all options with each company because the tools are lacking or are the tools lacking because the fab does not want to provide support.
That's because the x-axis is "pairwise allele-sharing distance" ie: we munged the data every which way to find something that we could use k-means clustering to write a paper.
A better graph would be a "pairwise interracial-fucking distance" with the y axis
the percentage of healthy babies born. That would be just one cluster.
3. Come to a complete halt in a tunnel with busy high speed traffic for no apparent reason.
And the excuse that the driver should have been ready to take over within fractions of a second
of the Tesla making a mistake while in FSD is absurd expectations on human reflexes and attention.
Merging works great. Drag multiple files to the main window. A dialog pops up to allow you to select the order of the files. Then merge and a new merged file is created.
