Testbench simulations are now all working correctly with the pre-release version of sky130_fd_io.
A template SoC for Google SKY130 free shuttles. It is still WIP. The current SoC architecture is given below.
The managment SoC runs firmware taht can be used to:
The memory map of the management SoC is given below
This is the user space. It has limitted silicon area (???) as well as a fixed number of I/O pads (???). The repoo contains a sample mega project that contains a binary 32-bit up counter.
The firmware running on the Management Area SoC, configures the I/O pads used by the counter and uses the logic probes to observe/control the counter. Three firmware examples are provided:
