Hi everyone! I wanted to get some guidance around enabling mixed signal support/analog design in my chip design. I do not see any template for that in TT07. I have some digital and analog components. Any suggestions?

Depending on the balance or what you find easiest, you can either instanciate an analog macro inside a digital design or the other way around, build the digital logic separately and then instanciate it as a sub block into a larger analog design and wire it up.

Greetings, I did the b) version of what Sylvain's talking about for TT06 and you can see a bit more on that project here: https://github.com/psychogenic/tt06-analog-wowa/blob/main/docs/info.md The tricky part was that taking the .mag file for the openlane digital blob and sticking it in my analog design wound up in a situation where magic was munging my standard cells. The solution is described, without tons of detail, here: https://github.com/psychogenic/tt06-analog-wowa/blob/main/openlane/README.md Also, you'd best constrain your digital design die size--otherwise mods to it may cause all the pads to jiggle around leading to lots of rewiring (which happened to me and was fun).
