Split the high voltage part of the mgmt_protect.v module into its own module called mgmt_protect_hv.v so that it can be synthesized separately into a hard macro, then included into the mgmt_protect.v block.
A template SoC for Google SKY130 free shuttles. It is still WIP. The current SoC architecture is given below.
The managment SoC runs firmware that can be used to:
The memory map of the management SoC can be found here
This is the user space. It has limited silicon area (TBD, about 3.1mm x 3.8mm) as well as a fixed number of I/O pads (37) and power pads (10). See the Caravel premliminary datasheet for details. The repository 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:
