Update README.md
In order to get the caravel_fulgor_opamp project running several tools and files need to be installed. To simplify the installation and to make sure you fullfill all the pre-requisites an install_pdk.sh script is provided. To run the script just type on the console:
./install_pdk.sh
This script does the following:
This project is a test chip, which contains several two stages operationals amplifiers with Miller compensation. This is an all analog desing implemented on the Google-Skywater 130nm Open Source PDK. It is an Open Source project under[Apache License 2.0] (LICENSE).
The OpAmp desing is located in an Open Source SoC Harness obtained from the efabless Caravel Project.
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:
