Wow! I have not done the video series yet, but I am anxious to. I am a system administrator for an ECE Department any you explained in the first video something that took a long time to figure out. I wish I had found this video previously and seen it 15 years ago..... I have since "worked" with (set up for use) PDKs from TSMC, IBM, INTEL (and signed NDAs) for researchers to use, but there as I am not an electrical engineer some things are still not precisely clear since I have not built a circuit. Again, looking forward to watching the video series.
FreePDK45 is a completely fictional process, so there isn't a foundry to which we can send the designs made in this PDK. "Real" PDKs by actual foundries usually require you to sign a very hefty non-disclosure agreement, which means I can't show the PDK in a video here on youtube. However, FreePDK45 is good enough for getting a first grasp of how Cadence works and basic schematic-/layout-based circuit design.
