Design the Project with ARM-M3 Core

Design the Project with ARM-M3 Core

1. The best part of Digilent Arty S7 can be prototype platform for Cortex DesignStart  Project. That is to customized one ARM-core MCU with Xilinx FPGA as simulation Platform. Here is the development flow.

2 Download the AT426-BU-98000-r0p1-00rel0.tgz from ARM website and decompress the archive.

3 Start Vivado and open tcl  console

image

run "exec subst V: ." to set virtual disk V: for installation directory, then add the ARM_IP in settings

image

open the hardware project

image

ignore the warning message concerning test-bench for simulation.

Here is the block design for ARM-M3 core

All the ARM_IP under the directory is imported through IP-integer , then synthesis and implement the project after execute "source make_mmi_files.tcl"

image

export the hardware file in .xsa

4 The arm-m3 hardware is ready to be coded with Keil MDK.

    This is so-called Design Start Project by ARM, offer free ARM-M0 core to start-ups based on FPGA platform. The Keil Essential is part of the bundle.

    The only problem is the Official Guide with Vivado 2018 use Xilinx XSDK, now part of Vitis after 2019.2. If strictly follow the guide, I need to downgrade my Vivado version. I am finding what fit best for new Vivado Version and Other out of the boundle IDE like Keil Community version.

    Microblaze is similar in principle , but more user-friendly and free to use for Xilinx chips. 

    But ARM is more versatile and scalable, it worth the time and effort to try.

    In fact , RISC-V core is supported as well. It is mixture of both ARM core and Microblaze, free license, scalable softcore stacks, but too fragmental and with little documentary and hard to grasp.

  • I was pondering too if I'd try an ARM soft core. 

    I see you're using Keil. I thought that Vitis supported Microblaze and ARM soft cores (and ARM real cores in SoCs like the Zynq)?
