Let’s take a back seat and appreciate the kind of amazing work done by @Praharsha on developing a basic mixed signal flow from scratch using efabless openlane pnr + google/sky130nm open-process

Praharsha had joined VSD Internship 7weeks back, with minimal clue about openlane/open-source/analog/IP’s. But she worked out, co-ordinated with experts and came up with a mixed signal PNR flow. The way she worked was in par with most of experienced people we work with.

The basic AMUX was built from scratch using transistors, then built double height layout and PNR using openlane. This flow will be helpful for anyone looking to PNR analog macros

Really thankful to @Mohamed Kaseem @Mohamed Shalan @Tim Edwards @Ahmed Ghazyfor helping @Praharsha at every stage of this experiment. Amazing experiment and documentation done here 👍👍

Read below Post for more details, and let’s take a moment to Congratulate her on LinkedIn. Your support will be really motivating for others to jump in and work on open-source VLSI.
