Aside: the press release is a bit more specific than all ECAD software, the language it uses is "Electronic Computer-Aided Design (ECAD) software specially designed for the development of integrated circuits with Gate-All-Around Field-Effect Transistor (GAAFET) structure".[1]

I'm not all that clued up on the latest in chip manufacturing, but GAAFET seems like a fairly cutting edge thing used only in high-end modern chips, and I wouldn't be surprised if many ECAD softare packages are unaffected (but again, this is not my field, so could be 100% wrong there, which I am sure people will point out).
