ابتدا(Ibtida) SoC - Google SKY130 Shuttle

An Soc designed to be included inside the Caravel, a template SoC for Google SKY130 free shuttles.

ابتدا means the start of something. This is a minimal SoC built around a RISC-V based 5 stage pipelined core Buraq-Mini. Both the SoC and the core are made from scratch using CHISEL HDL. The CHISEL source code as well as the emitted verilog are provided in the relvant folders. It is still Work In Progress (WIP). The current SoC architecture is given below.

Design hierarchy

Chisel source code is available here:
