This video updates my previous video on a mini-SoC for the Tang Nano 9K built using the PicoRV32 core. Now the SRAM is created by inference, and its size can be changed easily. In addition, it shows the Gowan Analysis Oscilloscope (GAO) working with this project.

The inferred-SRAM version is on a branch. To get it:
git clone https://github.com/grughuhler/picorv3...
cd picorv32
git checkout -b infer_sram remotes/origin/infer_sram
But also consider https://github.com/grughuhler/picorv3... for a later and better maintained version of the Mini-SoC with features described in later videos.
