AFT-X04

Goal: AFT-X04 is an attempt at creating a simple microcontroller centered around a RISC-V core.  
It features a richer set of peripherals than AFT-X03 and includes interrupts.

Status:

AFT-X04 is currently under design and verification.

AFT-X03

Goal: AFT-X03's main focus was to create an SoC with basic functionality.  The only supported
peripheral is GPIO. This was the team's first attempt at on-chip SRAM.  The simplicity of the
chip allows us to focus on establishing a team design flow before moving onto more complex designs.

Status:

AFT-X03 is taped out and is currently under bring-up.

AFT-X01/AFT-X02

Goal: AFT-X01 and AFT-X02 wwere the team's first attempt at designing and taping-out an SoC.  
Both chips have the same architecture. The bus structure of this chip was adopted by all of
our current SoCs.

Status:

AFT-X01 had an error in the power distribution and could not successfully be powered up.

AFT-X02 was successfully powered on during bring-up. We were able to communicate with the debugger through UART.
